    description The openSUSE Leap 42.3 kernel was updated to 4.4.114 to receive various security and bugfixes. The following security bugs were fixed : - CVE-2017-5715: Systems with microprocessors utilizing speculative execution and indirect branch prediction may allow unauthorized disclosure of information to an attacker with local user access via a side-channel analysis (bnc#1068032). The previous fix using CPU Microcode has been complemented by building the Linux Kernel with return trampolines aka 'retpolines'. - CVE-2018-5333: In the Linux kernel the rds_cmsg_atomic function in net/rds/rdma.c mishandled cases where page pinning fails or an invalid address is supplied, leading to an rds_atomic_free_op NULL pointer dereference (bnc#1075617). - CVE-2018-5332: In the Linux kernel the rds_message_alloc_sgs() function did not validate a value that is used during DMA page allocation, leading to a heap-based out-of-bounds write (related to the rds_rdma_extra_size function in net/rds/rdma.c) (bnc#1075621). - CVE-2017-17862: kernel/bpf/verifier.c in the Linux kernel ignores unreachable code, even though it would still be processed by JIT compilers. This behavior, also considered an improper branch-pruning logic issue, could possibly be used by local users for denial of service (bnc#1073928). - CVE-2017-17864: kernel/bpf/verifier.c in the Linux kernel mishandled states_equal comparisons between the pointer data type and the UNKNOWN_VALUE data type, which allowed local users to obtain potentially sensitive address information, aka a 'pointer leak (bnc#1073928). - CVE-2017-17712: The raw_sendmsg() function in net/ipv4/raw.c in the Linux kernel had a race condition in inet->hdrincl that lead to uninitialized stack pointer usage; this allowed a local user to execute code and gain privileges (bnc#1073229 1073230). - CVE-2017-15129: A use-after-free vulnerability was found in network namespaces code affecting the Linux kernel The function get_net_ns_by_id() in net/core/net_namespace.c did not check for the net::count value after it has found a peer network in netns_ids idr, which could lead to double free and memory corruption. This vulnerability could allow an unprivileged local user to induce kernel memory corruption on the system, leading to a crash. Due to the nature of the flaw, privilege escalation cannot be fully ruled out, although it is thought to be unlikely (bnc#1074839). - CVE-2017-18017: The tcpmss_mangle_packet function in net/netfilter/xt_TCPMSS.c in the Linux kernel allowed remote attackers to cause a denial of service (use-after-free and memory corruption) or possibly have unspecified other impact by leveraging the presence of xt_TCPMSS in an iptables action (bnc#1074488). - CVE-2018-1000004: In the Linux kernel versions a race condition vulnerability existed in the sound system, this can lead to a deadlock and denial of service condition (bnc#1076017). The following non-security bugs were fixed : - 509: fix printing uninitialized stack memory when OID is empty (bsc#1075078). - 8021q: fix a memory leak for VLAN 0 device (bnc#1012382). - acpi / scan: Prefer devices without _HID/_CID for _ADR matching (bnc#1012382). -

    title openSUSE Security Update : the Linux Kernel (openSUSE-2018-153) (Spectre)
  • NASL family SuSE Local Security Checks
    NASL id SUSE_SU-2018-0383-1.NASL
    description The SUSE Linux Enterprise 12 SP3 kernel was updated to 4.4.114 to receive various security and bugfixes. The following security bugs were fixed : - CVE-2017-5715: Systems with microprocessors utilizing speculative execution and indirect branch prediction may allow unauthorized disclosure of information to an attacker with local user access via a side-channel analysis (bnc#1068032). The previous fix using CPU Microcode has been complemented by building the Linux Kernel with return trampolines aka 'retpolines'. - CVE-2017-15129: A use-after-free vulnerability was found in network namespaces code affecting the Linux kernel in the function get_net_ns_by_id() in net/core/net_namespace.c did not check for the net::count value after it has found a peer network in netns_ids idr, which could lead to double free and memory corruption. This vulnerability could allow an unprivileged local user to induce kernel memory corruption on the system, leading to a crash. Due to the nature of the flaw, privilege escalation cannot be fully ruled out, although it is thought to be unlikely (bnc#1074839). - CVE-2017-17712: The raw_sendmsg() function in net/ipv4/raw.c in the Linux kernel has a race condition in inet->hdrincl that leads to uninitialized stack pointer usage; this allowed a local user to execute code and gain privileges (bnc#1073229). - CVE-2017-17862: kernel/bpf/verifier.c in the Linux kernel ignored unreachable code, even though it would still be processed by JIT compilers. This behavior, also considered an improper branch-pruning logic issue, could possibly be used by local users for denial of service (bnc#1073928). - CVE-2017-17864: kernel/bpf/verifier.c in the Linux kernel mishandled states_equal comparisons between the pointer data type and the UNKNOWN_VALUE data type, which allowed local users to obtain potentially sensitive address information, aka a 'pointer leak (bnc#1073928). - CVE-2017-18017: The tcpmss_mangle_packet function in net/netfilter/xt_TCPMSS.c in the Linux kernel allowed remote attackers to cause a denial of service (use-after-free and memory corruption) or possibly have unspecified other impact by leveraging the presence of xt_TCPMSS in an iptables action (bnc#1074488). - CVE-2018-5332: In the Linux kernel the rds_message_alloc_sgs() function did not validate a value that is used during DMA page allocation, leading to a heap-based out-of-bounds write (related to the rds_rdma_extra_size function in net/rds/rdma.c) (bnc#1075621). - CVE-2018-5333: In the Linux kernel the rds_cmsg_atomic function in net/rds/rdma.c mishandled cases where page pinning fails or an invalid address is supplied, leading to an rds_atomic_free_op NULL pointer dereference (bnc#1075617). - CVE-2018-1000004: In the Linux kernel a race condition vulnerability existed in the sound system, this can lead to a deadlock and denial of service condition (bnc#1076017). The update package also includes non-security fixes. See advisory for details. Note that Tenable Network Security has extracted the preceding description block directly from the SUSE security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

    description According to the versions of the kernel packages installed, the EulerOS installation on the remote host is affected by the following vulnerabilities : - The hid_input_field function in drivers/hid/hid-core.c in the Linux kernel before 4.6 allows physically proximate attackers to obtain sensitive information from kernel memory or cause a denial of service (out-of-bounds read) by connecting a device, as demonstrated by a Logitech DJ receiver.(CVE-2016-7915) - In the Linux kernel through 4.14.13, drivers/block/loop.c mishandles lo_release serialization, which allows attackers to cause a denial of service (__lock_acquire use-after-free) or possibly have unspecified other impact.(CVE-2018-5344) - In the Linux kernel through 4.14.13, the rds_cmsg_atomic() function in 'net/rds/rdma.c' mishandles cases where page pinning fails or an invalid address is supplied by a user. This can lead to a NULL pointer dereference in rds_atomic_free_op() and thus to a system panic.(CVE-2018-5333) - In the Linux kernel through 4.14.13, the rds_message_alloc_sgs() function does not validate a value that is used during DMA page allocation, leading to a heap-based out-of-bounds write (related to the rds_rdma_extra_size() function in 'net/rds/rdma.c') and thus to a system panic. Due to the nature of the flaw, privilege escalation cannot be fully ruled out, although we believe it is unlikely.(CVE-2018-5332) - A flaw was found in the upstream kernel Skcipher component. This vulnerability affects the skcipher_recvmsg function of the component Skcipher. The manipulation with an unknown input leads to a privilege escalation vulnerability.(CVE-2017-13215) - The tcpmss_mangle_packet function in net/netfilter/xt_TCPMSS.c in the Linux kernel before 4.11, and 4.9.x before 4.9.36, allows remote attackers to cause a denial of service (use-after-free and memory corruption) or possibly have unspecified other impact by leveraging the presence of xt_TCPMSS in an iptables action.(CVE-2017-18017) - The Salsa20 encryption algorithm in the Linux kernel before 4.14.8 does not correctly handle zero-length inputs, allowing a local attacker able to use the AF_ALG-based skcipher interface (CONFIG_CRYPTO_USER_API_SKCIPHER) to cause a denial of service (uninitialized-memory free and kernel crash) or have unspecified other impact by executing a crafted sequence of system calls that use the blkcipher_walk API. Both the generic implementation (crypto/salsa20_generic.c) and x86 implementation (arch/x86/crypto/salsa20_glue.c) of Salsa20 were vulnerable.(CVE-2017-17805) - The HMAC implementation (crypto/hmac.c) in the Linux kernel before 4.14.8 does not validate that the underlying cryptographic hash algorithm is unkeyed, allowing a local attacker able to use the AF_ALG-based hash interface (CONFIG_CRYPTO_USER_API_HASH) and the SHA-3 hash algorithm (CONFIG_CRYPTO_SHA3) to cause a kernel stack buffer overflow by executing a crafted sequence of system calls that encounter a missing SHA-3 initialization.(CVE-2017-17806) - he KEYS subsystem in the Linux kernel before 4.14.6 omitted an access-control check when adding a key to the current task's 'default request-key keyring' via the request_key() system call, allowing a local user to use a sequence of crafted system calls to add keys to a keyring with only Search permission (not Write permission) to that keyring, related to construct_get_dest_keyring() in security/keys/request_key.c.(CVE-2017-17807) - The Linux Kernel 2.6.32 and later are affected by a denial of service, by flooding the diagnostic port 0x80 an exception can be triggered leading to a kernel panic.(CVE-2017-1000407) - The XFRM dump policy implementation in net/xfrm/xfrm_user.c in the Linux kernel before 4.13.11 allows local users to gain privileges or cause a denial of service (use-after-free) via a crafted SO_RCVBUF setsockopt system call in conjunction with XFRM_MSG_GETPOLICY Netlink messages.(CVE-2017-16939) - The dccp_disconnect function in net/dccp/proto.c in the Linux kernel through 4.14.3 allows local users to gain privileges or cause a denial of service (use-after-free) via an AF_UNSPEC connect system call during the DCCP_LISTEN state.(CVE-2017-8824) - net/netfilter/nfnetlink_cthelper.c in the Linux kernel through 4.14.4 does not require the CAP_NET_ADMIN capability for new, get, and del operations, which allows local users to bypass intended access restrictions because the nfnl_cthelper_list data structure is shared across all net namespaces.(CVE-2017-17448) - Use-after-free vulnerability in the snd_pcm_info function in the ALSA subsystem in the Linux kernel allows attackers to gain privileges via unspecified vectors.(CVE-2017-0861) - The usb_destroy_configuration function in drivers/usb/core/config.c in the USB core subsystem in the Linux kernel through 4.14.5 does not consider the maximum number of configurations and interfaces before attempting to release resources, which allows local users to cause a denial of service (out-of-bounds write access) or possibly have unspecified other impact via a crafted USB device.(CVE-2017-17558) - The __netlink_deliver_tap_skb function in net/netlink/af_netlink.c in the Linux kernel through 4.14.4, when CONFIG_NLMON is enabled, does not restrict observations of Netlink messages to a single net namespace, which allows local users to obtain sensitive information by leveraging the CAP_NET_ADMIN capability to sniff an nlmon interface for all Netlink activity on the system.(CVE-2017-17449) - net/netfilter/xt_osf.c in the Linux kernel through 4.14.4 does not require the CAP_NET_ADMIN capability for add_callback and remove_callback operations, which allows local users to bypass intended access restrictions because the xt_osf_fingers data structure is shared across all net namespaces.(CVE-2017-17450) - The bnep_add_connection function in net/bluetooth/bnep/core.c in the Linux kernel before 3.19 does not ensure that an l2cap socket is available, which allows local users to gain privileges via a crafted application.(CVE-2017-15868) - The einj_error_inject function in drivers/acpi/apei/einj.c in the Linux kernel allows local users to simulate hardware errors and consequently cause a denial of service by leveraging failure to disable APEI error injection through EINJ when securelevel is set.(CVE-2016-3695) Note that Tenable Network Security has extracted the preceding description block directly from the EulerOS security advisory.

    title Scientific Linux Security Update : kernel on SL7.x x86_64 (Meltdown)
  • NASL family SuSE Local Security Checks
    NASL id SUSE_SU-2018-0834-1.NASL
    description The SUSE Linux Enterprise 12 kernel was updated to receive various security and bugfixes. The following security bugs were fixed : - CVE-2018-1068: Fixed flaw in the implementation of 32-bit syscall interface for bridging. This allowed a privileged user to arbitrarily write to a limited range of kernel memory (bnc#1085107). - CVE-2017-18221: The __munlock_pagevec function allowed local users to cause a denial of service (NR_MLOCK accounting corruption) via crafted use of mlockall and munlockall system calls (bnc#1084323). - CVE-2018-1066: Prevent NULL pointer dereference in fs/cifs/cifsencrypt.c:setup_ntlmv2_rsp() that allowed an attacker controlling a CIFS server to kernel panic a client that has this server mounted, because an empty TargetInfo field in an NTLMSSP setup negotiation response was mishandled during session recovery (bnc#1083640). - CVE-2017-13166: Prevent elevation of privilege vulnerability in the kernel v4l2 video driver (bnc#1072865). - CVE-2017-16911: The vhci_hcd driver allowed local attackers to disclose kernel memory addresses. Successful exploitation required that a USB device was attached over IP (bnc#1078674). - CVE-2017-15299: The KEYS subsystem mishandled use of add_key for a key that already exists but is uninstantiated, which allowed local users to cause a denial of service (NULL pointer dereference and system crash) or possibly have unspecified other impact via a crafted system call (bnc#1063416). - CVE-2017-18208: The madvise_willneed function kernel allowed local users to cause a denial of service (infinite loop) by triggering use of MADVISE_WILLNEED for a DAX mapping (bnc#1083494). - CVE-2018-7566: The ALSA sequencer core initializes the event pool on demand by invoking snd_seq_pool_init() when the first write happens and the pool is empty. A user could have reset the pool size manually via ioctl concurrently, which may have lead UAF or out-of-bound access (bsc#1083483). - CVE-2017-18204: The ocfs2_setattr function allowed local users to cause a denial of service (deadlock) via DIO requests (bnc#1083244). - CVE-2017-16644: The hdpvr_probe function allowed local users to cause a denial of service (improper error handling and system crash) or possibly have unspecified other impact via a crafted USB device (bnc#1067118). - CVE-2018-6927: The futex_requeue function allowed attackers to cause a denial of service (integer overflow) or possibly have unspecified other impact by triggering a negative wake or requeue value (bnc#1080757). - CVE-2017-16914: The 'stub_send_ret_submit()' function allowed attackers to cause a denial of service (NULL pointer dereference) via a specially crafted USB over IP packet (bnc#1078669). - CVE-2016-7915: The hid_input_field function allowed physically proximate attackers to obtain sensitive information from kernel memory or cause a denial of service (out-of-bounds read) by connecting a device (bnc#1010470). - CVE-2017-12190: The bio_map_user_iov and bio_unmap_user functions did unbalanced refcounting when a SCSI I/O vector had small consecutive buffers belonging to the same page. The bio_add_pc_page function merged them into one, but the page reference was never dropped. This caused a memory leak and possible system lockup (exploitable against the host OS by a guest OS user, if a SCSI disk is passed through to a virtual machine) due to an out-of-memory condition (bnc#1062568). - CVE-2017-16912: The 'get_pipe()' function allowed attackers to cause a denial of service (out-of-bounds read) via a specially crafted USB over IP packet (bnc#1078673). - CVE-2017-16913: The 'stub_recv_cmd_submit()' function when handling CMD_SUBMIT packets allowed attackers to cause a denial of service (arbitrary memory allocation) via a specially crafted USB over IP packet (bnc#1078672). - CVE-2018-5332: The rds_message_alloc_sgs() function did not validate a value that is used during DMA page allocation, leading to a heap-based out-of-bounds write (related to the rds_rdma_extra_size function in net/rds/rdma.c) (bnc#1075621). - CVE-2018-5333: The rds_cmsg_atomic function in net/rds/rdma.c mishandled cases where page pinning fails or an invalid address is supplied, leading to an rds_atomic_free_op NULL pointer dereference (bnc#1075617). - CVE-2017-18017: The tcpmss_mangle_packet function allowed remote attackers to cause a denial of service (use-after-free and memory corruption) or possibly have unspecified other impact by leveraging the presence of xt_TCPMSS in an iptables action (bnc#1074488). The update package also includes non-security fixes. See advisory for details. Note that Tenable Network Security has extracted the preceding description block directly from the SUSE security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

    title SUSE SLES12 Security Update : kernel (SUSE-SU-2018:0848-1)
  • NASL family Debian Local Security Checks
    NASL id DEBIAN_DSA-4187.NASL
    description Several vulnerabilities have been discovered in the Linux kernel that may lead to a privilege escalation, denial of service or information leaks. - CVE-2015-9016 Ming Lei reported a race condition in the multiqueue block layer (blk-mq). On a system with a driver using blk-mq (mtip32xx, null_blk, or virtio_blk), a local user might be able to use this for denial of service or possibly for privilege escalation. - CVE-2017-0861 Robb Glasser reported a potential use-after-free in the ALSA (sound) PCM core. We believe this was not possible in practice. - CVE-2017-5715 Multiple researchers have discovered a vulnerability in various processors supporting speculative execution, enabling an attacker controlling an unprivileged process to read memory from arbitrary addresses, including from the kernel and all other processes running on the system. This specific attack has been named Spectre variant 2 (branch target injection) and is mitigated for the x86 architecture (amd64 and i386) by using the 'retpoline' compiler feature which allows indirect branches to be isolated from speculative execution. - CVE-2017-5753 Multiple researchers have discovered a vulnerability in various processors supporting speculative execution, enabling an attacker controlling an unprivileged process to read memory from arbitrary addresses, including from the kernel and all other processes running on the system. This specific attack has been named Spectre variant 1 (bounds-check bypass) and is mitigated by identifying vulnerable code sections (array bounds checking followed by array access) and replacing the array access with the speculation-safe array_index_nospec() function. More use sites will be added over time. - CVE-2017-13166 A bug in the 32-bit compatibility layer of the v4l2 ioctl handling code has been found. Memory protections ensuring user-provided buffers always point to userland memory were disabled, allowing destination addresses to be in kernel space. On a 64-bit kernel a local user with access to a suitable video device can exploit this to overwrite kernel memory, leading to privilege escalation. - CVE-2017-13220 Al Viro reported that the Bluetooth HIDP implementation could dereference a pointer before performing the necessary type check. A local user could use this to cause a denial of service. - CVE-2017-16526 Andrey Konovalov reported that the UWB subsystem may dereference an invalid pointer in an error case. A local user might be able to use this for denial of service. - CVE-2017-16911 Secunia Research reported that the USB/IP vhci_hcd driver exposed kernel heap addresses to local users. This information could aid the exploitation of other vulnerabilities. - CVE-2017-16912 Secunia Research reported that the USB/IP stub driver failed to perform a range check on a received packet header field, leading to an out-of-bounds read. A remote user able to connect to the USB/IP server could use this for denial of service. - CVE-2017-16913 Secunia Research reported that the USB/IP stub driver failed to perform a range check on a received packet header field, leading to excessive memory allocation. A remote user able to connect to the USB/IP server could use this for denial of service. - CVE-2017-16914 Secunia Research reported that the USB/IP stub driver failed to check for an invalid combination of fields in a received packet, leading to a NULL pointer dereference. A remote user able to connect to the USB/IP server could use this for denial of service. - CVE-2017-18017 Denys Fedoryshchenko reported that the netfilter xt_TCPMSS module failed to validate TCP header lengths, potentially leading to a use-after-free. If this module is loaded, it could be used by a remote attacker for denial of service or possibly for code execution. - CVE-2017-18203 Hou Tao reported that there was a race condition in creation and deletion of device-mapper (DM) devices. A local user could potentially use this for denial of service. - CVE-2017-18216 Alex Chen reported that the OCFS2 filesystem failed to hold a necessary lock during nodemanager sysfs file operations, potentially leading to a NULL pointer dereference. A local user could use this for denial of service. - CVE-2017-18232 Jason Yan reported a race condition in the SAS (Serial-Attached SCSI) subsystem, between probing and destroying a port. This could lead to a deadlock. A physically present attacker could use this to cause a denial of service. - CVE-2017-18241 Yunlei He reported that the f2fs implementation does not properly initialise its state if the 'noflush_merge' mount option is used. A local user with access to a filesystem mounted with this option could use this to cause a denial of service. - CVE-2018-1066 Dan Aloni reported to Red Hat that the CIFS client implementation would dereference a NULL pointer if the server sent an invalid response during NTLMSSP setup negotiation. This could be used by a malicious server for denial of service. - CVE-2018-1068 The syzkaller tool found that the 32-bit compatibility layer of ebtables did not sufficiently validate offset values. On a 64-bit kernel, a local user with the CAP_NET_ADMIN capability (in any user namespace) could use this to overwrite kernel memory, possibly leading to privilege escalation. Debian disables unprivileged user namespaces by default. - CVE-2018-1092 Wen Xu reported that a crafted ext4 filesystem image would trigger a null dereference when mounted. A local user able to mount arbitrary filesystems could use this for denial of service. - CVE-2018-5332 Mohamed Ghannam reported that the RDS protocol did not sufficiently validate RDMA requests, leading to an out-of-bounds write. A local attacker on a system with the rds module loaded could use this for denial of service or possibly for privilege escalation. - CVE-2018-5333 Mohamed Ghannam reported that the RDS protocol did not properly handle an error case, leading to a NULL pointer dereference. A local attacker on a system with the rds module loaded could possibly use this for denial of service. - CVE-2018-5750 Wang Qize reported that the ACPI sbshc driver logged a kernel heap address. This information could aid the exploitation of other vulnerabilities. - CVE-2018-5803 Alexey Kodanev reported that the SCTP protocol did not range-check the length of chunks to be created. A local or remote user could use this to cause a denial of service. - CVE-2018-6927 Li Jinyue reported that the FUTEX_REQUEUE operation on futexes did not check for negative parameter values, which might lead to a denial of service or other security impact. - CVE-2018-7492 The syzkaller tool found that the RDS protocol was lacking a null pointer check. A local attacker on a system with the rds module loaded could use this for denial of service. - CVE-2018-7566 Fan LongFei reported a race condition in the ALSA (sound) sequencer core, between write and ioctl operations. This could lead to an out-of-bounds access or use-after-free. A local user with access to a sequencer device could use this for denial of service or possibly for privilege escalation. - CVE-2018-7740 Nic Losby reported that the hugetlbfs filesystem's mmap operation did not properly range-check the file offset. A local user with access to files on a hugetlbfs filesystem could use this to cause a denial of service. - CVE-2018-7757 Jason Yan reported a memory leak in the SAS (Serial-Attached SCSI) subsystem. A local user on a system with SAS devices could use this to cause a denial of service. - CVE-2018-7995 Seunghun Han reported a race condition in the x86 MCE (Machine Check Exception) driver. This is unlikely to have any security impact. - CVE-2018-8781 Eyal Itkin reported that the udl (DisplayLink) driver's mmap operation did not properly range-check the file offset. A local user with access to a udl framebuffer device could exploit this to overwrite kernel memory, leading to privilege escalation. - CVE-2018-8822 Dr Silvio Cesare of InfoSect reported that the ncpfs client implementation did not validate reply lengths from the server. An ncpfs server could use this to cause a denial of service or remote code execution in the client. - CVE-2018-1000004 Luo Quan reported a race condition in the ALSA (sound) sequencer core, between multiple ioctl operations. This could lead to a deadlock or use-after-free. A local user with access to a sequencer device could use this for denial of service or possibly for privilege escalation. - CVE-2018-1000199 Andy Lutomirski discovered that the ptrace subsystem did not sufficiently validate hardware breakpoint settings. Local users can use this to cause a denial of service, or possibly for privilege escalation, on x86 (amd64 and i386) and possibly other architectures.

    description The SUSE Linux Enterprise 11 SP4 kernel was updated to receive various security and bugfixes. The following security bugs were fixed : - CVE-2017-5715: Systems with microprocessors utilizing speculative execution and indirect branch prediction may allow unauthorized disclosure of information to an attacker with local user access via a side-channel analysis (bnc#1068032). The previous fix using CPU Microcode has been complemented by building the Linux Kernel with return trampolines aka 'retpolines'. - CVE-2018-5332: In the Linux kernel the rds_message_alloc_sgs() function did not validate a value that is used during DMA page allocation, leading to a heap-based out-of-bounds write (related to the rds_rdma_extra_size function in net/rds/rdma.c) (bnc#1075621). - CVE-2018-5333: In the Linux kernel the rds_cmsg_atomic function in net/rds/rdma.c mishandled cases where page pinning fails or an invalid address is supplied, leading to an rds_atomic_free_op NULL pointer dereference (bnc#1075617). - CVE-2017-18017: The tcpmss_mangle_packet function in net/netfilter/xt_TCPMSS.c in the Linux kernel allowed remote attackers to cause a denial of service (use-after-free and memory corruption) or possibly have unspecified other impact by leveraging the presence of xt_TCPMSS in an iptables action (bnc#1074488). - CVE-2017-18079: drivers/input/serio/i8042.c in the Linux kernel allowed attackers to cause a denial of service (NULL pointer dereference and system crash) or possibly have unspecified other impact because the port->exists value can change after it is validated (bnc#1077922). - CVE-2015-1142857: On multiple SR-IOV cars it is possible for VF's assigned to guests to send ethernet flow control pause frames via the PF. (bnc#1077355). - CVE-2017-17741: The KVM implementation in the Linux kernel allowed attackers to obtain potentially sensitive information from kernel memory, aka a write_mmio stack-based out-of-bounds read, related to arch/x86/kvm/x86.c and include/trace/events/kvm.h (bnc#1073311). - CVE-2017-13215: A elevation of privilege vulnerability in the Upstream kernel skcipher. (bnc#1075908). - CVE-2018-1000004: In the Linux kernel a race condition vulnerability existed in the sound system, this can lead to a deadlock and denial of service condition (bnc#1076017).

The previous fix using CPU Microcode has been complemented by building the Linux Kernel with return trampolines aka 'retpolines'. - CVE-2018-5332: In the Linux kernel the rds_message_alloc_sgs() function did not validate a value that is used during DMA page allocation, leading to a heap-based out-of-bounds write (related to the rds_rdma_extra_size function in net/rds/rdma.c) (bnc#1075621). - CVE-2018-5333: In the Linux kernel the rds_cmsg_atomic function in net/rds/rdma.c mishandled cases where page pinning fails or an invalid address is supplied, leading to an rds_atomic_free_op NULL pointer dereference (bnc#1075617). - CVE-2017-18017: The tcpmss_mangle_packet function in net/netfilter/xt_TCPMSS.c in the Linux kernel allowed remote attackers to cause a denial of service (use-after-free and memory corruption) or possibly have unspecified other impact by leveraging the presence of xt_TCPMSS in an iptables action (bnc#1074488). - CVE-2017-18079: drivers/input/serio/i8042.c in the Linux kernel allowed attackers to cause a denial of service (NULL pointer dereference and system crash) or possibly have unspecified other impact because the port->exists value can change after it is validated (bnc#1077922). - CVE-2017-17741: The KVM implementation in the Linux kernel allowed attackers to obtain potentially sensitive information from kernel memory, aka a write_mmio stack-based out-of-bounds read, related to arch/x86/kvm/x86.c and include/trace/events/kvm.h (bnc#1073311). - CVE-2017-13215: A elevation of privilege vulnerability in the Upstream kernel skcipher. (bnc#1075908). - CVE-2018-1000004: In the Linux kernel a race condition vulnerability exists in the sound system, this can lead to a deadlock and denial of service condition (bnc#1076017). The update package also includes non-security fixes. See advisory for details. Note that Tenable Network Security has extracted the preceding description block directly from the SUSE security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

    description Several vulnerabilities have been discovered in the Linux kernel that may lead to a privilege escalation, denial of service or information leaks. CVE-2017-0861 Robb Glasser reported a potential use-after-free in the ALSA (sound) PCM core. We believe this was not possible in practice. CVE-2017-5715 Multiple researchers have discovered a vulnerability in various processors supporting speculative execution, enabling an attacker controlling an unprivileged process to read memory from arbitrary addresses, including from the kernel and all other processes running on the system. This specific attack has been named Spectre variant 2 (branch target injection) and is mitigated for the x86 architecture (amd64 and i386) by using the 'retpoline' compiler feature which allows indirect branches to be isolated from speculative execution. CVE-2017-13166 A bug in the 32-bit compatibility layer of the v4l2 ioctl handling code has been found. Memory protections ensuring user-provided buffers always point to userland memory were disabled, allowing destination addresses to be in kernel space. On a 64-bit kernel (amd64 flavour) a local user with access to a suitable video device can exploit this to overwrite kernel memory, leading to privilege escalation. CVE-2017-16526 Andrey Konovalov reported that the UWB subsystem may dereference an invalid pointer in an error case. A local user might be able to use this for denial of service. CVE-2017-16911 Secunia Research reported that the USB/IP vhci_hcd driver exposed kernel heap addresses to local users. This information could aid the exploitation of other vulnerabilities. CVE-2017-16912 Secunia Research reported that the USB/IP stub driver failed to perform a range check on a received packet header field, leading to an out-of-bounds read. A remote user able to connect to the USB/IP server could use this for denial of service. CVE-2017-16913 Secunia Research reported that the USB/IP stub driver failed to perform a range check on a received packet header field, leading to excessive memory allocation. A remote user able to connect to the USB/IP server could use this for denial of service. CVE-2017-16914 Secunia Research reported that the USB/IP stub driver failed to check for an invalid combination of fields in a recieved packet, leading to a NULL pointer dereference. A remote user able to connect to the USB/IP server could use this for denial of service. CVE-2017-18017 Denys Fedoryshchenko reported that the netfilter xt_TCPMSS module failed to validate TCP header lengths, potentially leading to a use-after-free. If this module is loaded, it could be used by a remote attacker for denial of service or possibly for code execution. CVE-2017-18203 Hou Tao reported that there was a race condition in creation and deletion of device-mapper (DM) devices. A local user could potentially use this for denial of service. CVE-2017-18216 Alex Chen reported that the OCFS2 filesystem failed to hold a necessary lock during nodemanager sysfs file operations, potentially leading to a NULL pointer dereference. A local user could use this for denial of service. CVE-2018-1068 The syzkaller tool found that the 32-bit compatibility layer of ebtables did not sufficiently validate offset values. On a 64-bit kernel (amd64 flavour), a local user with the CAP_NET_ADMIN capability could use this to overwrite kernel memory, possibly leading to privilege escalation. CVE-2018-1092 Wen Xu reported that a crafted ext4 filesystem image would trigger a null dereference when mounted. A local user able to mount arbitrary filesystems could use this for denial of service. CVE-2018-5332 Mohamed Ghannam reported that the RDS protocol did not sufficiently validate RDMA requests, leading to an out-of-bounds write. A local attacker on a system with the rds module loaded could use this for denial of service or possibly for privilege escalation. CVE-2018-5333 Mohamed Ghannam reported that the RDS protocol did not properly handle an error case, leading to a NULL pointer dereference. A local attacker on a system with the rds module loaded could possibly use this for denial of service. CVE-2018-5750 Wang Qize reported that the ACPI sbshc driver logged a kernel heap address. This information could aid the exploitation of other vulnerabilities. CVE-2018-5803 Alexey Kodanev reported that the SCTP protocol did not range-check the length of chunks to be created. A local or remote user could use this to cause a denial of service. CVE-2018-6927 Li Jinyue reported that the FUTEX_REQUEUE operation on futexes did not check for negative parameter values, which might lead to a denial of service or other security impact. CVE-2018-7492 The syzkaller tool found that the RDS protocol was lacking a NULL pointer check. A local attacker on a system with the rds module loaded could use this for denial of service. CVE-2018-7566 范龙飞 (Fan LongFei) reported a race condition in the ALSA (sound) sequencer core, between write and ioctl operations. This could lead to an out-of-bounds access or use-after-free. A local user with access to a sequencer device could use this for denial of service or possibly for privilege escalation. CVE-2018-7740 Nic Losby reported that the hugetlbfs filesystem's mmap operation did not properly range-check the file offset. A local user with access to files on a hugetlbfs filesystem could use this to cause a denial of service. CVE-2018-7757 Jason Yan reported a memory leak in the SAS (Serial-Attached SCSI) subsystem. A local user on a system with SAS devices could use this to cause a denial of service. CVE-2018-7995 Seunghun Han reported a race condition in the x86 MCE (Machine Check Exception) driver. This is unlikely to have any security impact. CVE-2018-8781 Eyal Itkin reported that the udl (DisplayLink) driver's mmap operation did not properly range-check the file offset. A local user with access to a udl framebuffer device could exploit this to overwrite kernel memory, leading to privilege escalation. CVE-2018-8822 Dr Silvio Cesare of InfoSect reported that the ncpfs client implementation did not validate reply lengths from the server. An ncpfs server could use this to cause a denial of service or remote code execution in the client. CVE-2018-1000004 Luo Quan reported a race condition in the ALSA (sound) sequencer core, between multiple ioctl operations. This could lead to a deadlock or use-after-free. A local user with access to a sequencer device could use this for denial of service or possibly for privilege escalation. CVE-2018-1000199 Andy Lutomirski discovered that the ptrace subsystem did not sufficiently validate hardware breakpoint settings. Local users can use this to cause a denial of service, or possibly for privilege escalation, on x86 (amd64 and i386) and possibly other architectures. Additionally, some mitigations for CVE-2017-5753 are included in this release : CVE-2017-5753 Multiple researchers have discovered a vulnerability in various processors supporting speculative execution, enabling an attacker controlling an unprivileged process to read memory from arbitrary addresses, including from the kernel and all other processes running on the system. This specific attack has been named Spectre variant 1 (bounds-check bypass) and is mitigated by identifying vulnerable code sections (array bounds checking followed by array access) and replacing the array access with the speculation-safe array_index_nospec() function. More use sites will be added over time. For Debian 7 'Wheezy', these problems have been fixed in version 3.2.101-1. This version also includes bug fixes from upstream versions up to and including 3.2.101. It also fixes a regression in the procfs hidepid option in the previous version (Debian bug #887106). We recommend that you upgrade your linux packages. NOTE: Tenable Network Security has extracted the preceding description block directly from the DLA security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

    description An update for kernel is now available for Red Hat Enterprise Linux 7.3 Extended Update Support. Red Hat Product Security has rated this update as having a security impact of Important. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section. The kernel packages contain the Linux kernel, the core of any Linux operating system. Security Fix(es) : * An industry-wide issue was found in the way many modern microprocessor designs have implemented speculative execution of Load & Store instructions (a commonly used performance optimization). It relies on the presence of a precisely-defined instruction sequence in the privileged code as well as the fact that memory read from address to which a recent memory write has occurred may see an older value and subsequently cause an update into the microprocessor's data cache even for speculatively executed instructions that never actually commit (retire). As a result, an unprivileged attacker could use this flaw to read privileged memory by conducting targeted cache side-channel attacks. (CVE-2018-3639) Note: This issue is present in hardware and cannot be fully fixed via software update. The updated kernel packages provide software side of the mitigation for this hardware issue. To be fully functional, up-to-date CPU microcode applied on the system might be required. Please refer to References section for further information about this issue, CPU microcode requirements and the potential performance impact. In this update, mitigation for PowerPC architecture is provided. * kernel: netfilter: use-after-free in tcpmss_mangle_packet function in net/ netfilter/xt_TCPMSS.c (CVE-2017-18017) For more details about the security issue(s), including the impact, a CVSS score, and other related information, refer to the CVE page(s) listed in the References section. Red Hat would like to thank Ken Johnson (Microsoft Security Response Center) and Jann Horn (Google Project Zero) for reporting CVE-2018-3639. Bug Fix(es) : These updated kernel packages include also numerous bug fixes. Space precludes documenting all of these bug fixes in this advisory.

    title RHEL 7 : kernel (RHSA-2018:1062)
  • NASL family Virtuozzo Local Security Checks
    NASL id VIRTUOZZO_VZA-2018-017.NASL
    description According to the versions of the parallels-server-bm-release / etc packages installed, the Virtuozzo installation on the remote host is affected by the following vulnerabilities : - In the Linux kernel through 4.14.13, the rds_message_alloc_sgs() function does not validate a value that is used during DMA page allocation, leading to a heap-based out-of-bounds write (related to the rds_rdma_extra_size() function in 'net/rds/rdma.c') and thus to a system panic. - The rds_cmsg_atomic() function in 'net/rds/rdma.c' mishandles cases where page pinning fails or an invalid address is supplied by a user. This can lead to a NULL pointer dereference in rds_atomic_free_op() and thus to a system panic. - The tcpmss_mangle_packet function in net/netfilter/xt_TCPMSS.c allows remote attackers to cause a denial of service (use-after-free and memory corruption) or possibly have unspecified other impact by leveraging the presence of xt_TCPMSS in an iptables action. Note that Tenable Network Security has extracted the preceding description block directly from the Virtuozzo security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

  • NASL family Virtuozzo Local Security Checks
    NASL id VIRTUOZZO_VZA-2018-004.NASL
    description According to the version of the vzkernel package and the readykernel-patch installed, the Virtuozzo installation on the remote host is affected by the following vulnerabilities : - A vulnerability was found in DCCP socket handling code. dccp_disconnect() set the socket state to DCCP_CLOSED but did not properly free some of the resources associated with that socket. This could result in a use-after-free and could potentially allow an attacker to escalate their privileges. - The Linux kernel is vulnerable to a use-after-free issue. It could occur while closing a xfrm netlink socket, in xfrm_dump_policy_done. A user/process could use this flaw to potentially escalate their privileges on a system. - The function get_net_ns_by_id() does not check the net.count value when processing a peer network, which could lead to double free and memory corruption. An unprivileged local user could use this vulnerability to crash the system. - If the system uses iptables and there are iptables rules with TCPMSS action there, a remote attacker could cause a denial of service (use-after-free in tcpmss_mangle_packet function leading to memory corruption) or possibly have unspecified other impact by sending specially crafted network packets. - A flaw was found in the patches used to fix the 'Dirty COW' vulnerability (CVE-2016-5195). An attacker, able to run local code, could exploit a race condition in transparent huge pages to modify usually read-only huge pages. Note that Tenable Network Security has extracted the preceding description block directly from the Virtuozzo security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

    description An update for kernel-rt is now available for Red Hat Enterprise MRG 2. Red Hat Product Security has rated this update as having a security impact of Important. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section. The kernel-rt packages provide the Real Time Linux Kernel, which enables fine-tuning for systems with extremely high determinism requirements.

Red Hat would like to thank Mohamed Ghannam for reporting CVE-2017-8824 and Armis Labs for reporting CVE-2017-1000410. Bug Fix(es) : * The kernel-rt packages have been upgraded to version 3.10.0-693.25.2.rt56.612, which provides a number of security and bug fixes over the previous version. (BZ#1549731) * Intel Core X-Series (Skylake) processors use a hard-coded Time Stamp Counter (TSC) frequency of 25 MHz. In some cases this can be imprecise and lead to timing-related problems such as time drift, timers being triggered early, or TSC clock instability. This update mitigates these problems by no longer using the 'native_calibrate_tsc()' function to define the TSC frequency. Refined calibration is now used to update the clock rate accordingly in these cases. (BZ#1547854)

    NASL id EULEROS_SA-2018-1234.NASL
    description According to the versions of the kernel packages installed, the EulerOS Virtualization installation on the remote host is affected by the following vulnerabilities : - A use-after-free vulnerability was found in network namespaces code affecting the Linux kernel before 4.14.11. The function get_net_ns_by_id() in net/core/net_namespace.c does not check for the net::count value after it has found a peer network in netns_ids idr, which could lead to double free and memory corruption. This vulnerability could allow an unprivileged local user to induce kernel memory corruption on the system, leading to a crash. Due to the nature of the flaw, privilege escalation cannot be fully ruled out, although it is thought to be unlikely.(CVE-2017-15129) - The tcpmss_mangle_packet function in net/netfilter/xt_TCPMSS.c in the Linux kernel before 4.11, and 4.9.x before 4.9.36, allows remote attackers to cause a denial of service (use-after-free and memory corruption) or possibly have unspecified other impact by leveraging the presence of xt_TCPMSS in an iptables action.(CVE-2017-18017) - A flaw was found in the upstream kernel Skcipher component. This vulnerability affects the skcipher_recvmsg function of the component Skcipher. The manipulation with an unknown input leads to a privilege escalation vulnerability.(CVE-2017-13215) - In the Linux kernel through 4.14.13, the rds_message_alloc_sgs() function does not validate a value that is used during DMA page allocation, leading to a heap-based out-of-bounds write (related to the rds_rdma_extra_size() function in 'net/rds/rdma.c') and thus to a system panic. Due to the nature of the flaw, privilege escalation cannot be fully ruled out, although we believe it is unlikely.(CVE-2018-5332) - In the Linux kernel through 4.14.13, the rds_cmsg_atomic() function in 'net/rds/rdma.c' mishandles cases where page pinning fails or an invalid address is supplied by a user. This can lead to a NULL pointer dereference in rds_atomic_free_op() and thus to a system panic.(CVE-2018-5333) - drivers/input/serio/i8042.c in the Linux kernel before 4.12.4 allows attackers to cause a denial of service (NULL pointer dereference and system crash) or possibly have unspecified other impact because the port->exists value can change after it is validated.(CVE-2017-18079) Note that Tenable Network Security has extracted the preceding description block directly from the EulerOS security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

  • NASL family SuSE Local Security Checks
    NASL id SUSE_SU-2018-0416-1.NASL
    description The SUSE Linux Enterprise 12 SP2 kernel was updated to 4.4.114 to receive various security and bugfixes. The following security bugs were fixed : - CVE-2017-5715: Systems with microprocessors utilizing speculative execution and indirect branch prediction may allow unauthorized disclosure of information to an attacker with local user access via a side-channel analysis (bnc#1068032). The previous fix using CPU Microcode has been complemented by building the Linux Kernel with return trampolines aka 'retpolines'. - CVE-2017-15129: A use-after-free vulnerability was found in network namespaces code affecting the Linux kernel The function get_net_ns_by_id() in net/core/net_namespace.c did not check for the net::count value after it has found a peer network in netns_ids idr, which could lead to double free and memory corruption. This vulnerability could allow an unprivileged local user to induce kernel memory corruption on the system, leading to a crash. Due to the nature of the flaw, privilege escalation cannot be fully ruled out, although it is thought to be unlikely (bnc#1074839). - CVE-2017-17712: The raw_sendmsg() function in net/ipv4/raw.c in the Linux kernel has a race condition in inet->hdrincl that leads to uninitialized stack pointer usage; this allowed a local user to execute code and gain privileges (bnc#1073229). - CVE-2017-17862: kernel/bpf/verifier.c in the Linux kernel ignored unreachable code, even though it would still be processed by JIT compilers. This behavior, also considered an improper branch-pruning logic issue, could possibly be used by local users for denial of service (bnc#1073928). - CVE-2017-17864: kernel/bpf/verifier.c in the Linux kernel mishandled states_equal comparisons between the pointer data type and the UNKNOWN_VALUE data type, which allowed local users to obtain potentially sensitive address information, aka a 'pointer leak (bnc#1073928). - CVE-2017-18017: The tcpmss_mangle_packet function in net/netfilter/xt_TCPMSS.c in the Linux kernel allowed remote attackers to cause a denial of service (use-after-free and memory corruption) or possibly have unspecified other impact by leveraging the presence of xt_TCPMSS in an iptables action (bnc#1074488). - CVE-2018-1000004: In the Linux kernel a race condition vulnerability existed in the sound system, this can lead to a deadlock and denial of service condition (bnc#1076017). - CVE-2018-5332: In the Linux kernel the rds_message_alloc_sgs() function did not validate a value that is used during DMA page allocation, leading to a heap-based out-of-bounds write (related to the rds_rdma_extra_size function in net/rds/rdma.c) (bnc#1075621). - CVE-2018-5333: In the Linux kernel the rds_cmsg_atomic function in net/rds/rdma.c mishandled cases where page pinning fails or an invalid address is supplied, leading to an rds_atomic_free_op NULL pointer dereference (bnc#1075617). The update package also includes non-security fixes. See advisory for details. Note that Tenable Network Security has extracted the preceding description block directly from the SUSE security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
