  • NASL family SuSE Local Security Checks
    NASL id OPENSUSE-2016-1015.NASL
    description The openSUSE 13.2 kernel was updated to fix various bugs and security issues. The following security bugs were fixed : - CVE-2016-1583: Prevent the usage of mmap when the lower file system does not allow it. This could have lead to local privilege escalation when ecryptfs-utils was installed and /sbin/mount.ecryptfs_private was setuid (bsc#983143). - CVE-2016-4913: The get_rock_ridge_filename function in fs/isofs/rock.c in the Linux kernel mishandles NM (aka alternate name) entries containing \0 characters, which allowed local users to obtain sensitive information from kernel memory or possibly have unspecified other impact via a crafted isofs filesystem (bnc#980725). - CVE-2016-4580: The x25_negotiate_facilities function in net/x25/x25_facilities.c in the Linux kernel did not properly initialize a certain data structure, which allowed attackers to obtain sensitive information from kernel stack memory via an X.25 Call Request (bnc#981267). - CVE-2016-0758: Tags with indefinite length could have corrupted pointers in asn1_find_indefinite_length (bsc#979867). - CVE-2016-2053: The asn1_ber_decoder function in lib/asn1_decoder.c in the Linux kernel allowed attackers to cause a denial of service (panic) via an ASN.1 BER file that lacks a public key, leading to mishandling by the public_key_verify_signature function in crypto/asymmetric_keys/public_key.c (bnc#963762). - CVE-2016-2187: The gtco_probe function in drivers/input/tablet/gtco.c in the Linux kernel allowed physically proximate attackers to cause a denial of service (NULL pointer dereference and system crash) via a crafted endpoints value in a USB device descriptor (bnc#971919 971944). - CVE-2016-4482: The proc_connectinfo function in drivers/usb/core/devio.c in the Linux kernel did not initialize a certain data structure, which allowed local users to obtain sensitive information from kernel stack memory via a crafted USBDEVFS_CONNECTINFO ioctl call (bnc#978401 bsc#978445). - CVE-2016-4565: The InfiniBand (aka IB) stack in the Linux kernel incorrectly relies on the write system call, which allowed local users to cause a denial of service (kernel memory write operation) or possibly have unspecified other impact via a uAPI interface (bnc#979548 bsc#980363). - CVE-2016-3672: The arch_pick_mmap_layout function in arch/x86/mm/mmap.c in the Linux kernel did not properly randomize the legacy base address, which made it easier for local users to defeat the intended restrictions on the ADDR_NO_RANDOMIZE flag, and bypass the ASLR protection mechanism for a setuid or setgid program, by disabling stack-consumption resource limits (bnc#974308). - CVE-2016-4581: fs/pnode.c in the Linux kernel did not properly traverse a mount propagation tree in a certain case involving a slave mount, which allowed local users to cause a denial of service (NULL pointer dereference and OOPS) via a crafted series of mount system calls (bnc#979913). - CVE-2016-4485: The llc_cmsg_rcv function in net/llc/af_llc.c in the Linux kernel did not initialize a certain data structure, which allowed attackers to obtain sensitive information from kernel stack memory by reading a message (bnc#978821). - CVE-2015-3288: A security flaw was found in the Linux kernel that there was a way to arbitrary change zero page memory. (bnc#979021). - CVE-2016-4578: sound/core/timer.c in the Linux kernel did not initialize certain r1 data structures, which allowed local users to obtain sensitive information from kernel stack memory via crafted use of the ALSA timer interface, related to the (1) snd_timer_user_ccallback and (2) snd_timer_user_tinterrupt functions (bnc#979879). - CVE-2016-3134: The netfilter subsystem in the Linux kernel did not validate certain offset fields, which allowed local users to gain privileges or cause a denial of service (heap memory corruption) via an IPT_SO_SET_REPLACE setsockopt call (bnc#971126). - CVE-2016-4486: The rtnl_fill_link_ifmap function in net/core/rtnetlink.c in the Linux kernel did not initialize a certain data structure, which allowed local users to obtain sensitive information from kernel stack memory by reading a Netlink message (bnc#978822). - CVE-2013-7446: Use-after-free vulnerability in net/unix/af_unix.c in the Linux kernel allowed local users to bypass intended AF_UNIX socket permissions or cause a denial of service (panic) via crafted epoll_ctl calls (bnc#955654). - CVE-2016-4569: The snd_timer_user_params function in sound/core/timer.c in the Linux kernel did not initialize a certain data structure, which allowed local users to obtain sensitive information from kernel stack memory via crafted use of the ALSA timer interface (bnc#979213). - CVE-2016-2847: fs/pipe.c in the Linux kernel did not limit the amount of unread data in pipes, which allowed local users to cause a denial of service (memory consumption) by creating many pipes with non-default sizes (bnc#970948 974646). - CVE-2016-3136: The mct_u232_msr_to_state function in drivers/usb/serial/mct_u232.c in the Linux kernel allowed physically proximate attackers to cause a denial of service (NULL pointer dereference and system crash) via a crafted USB device without two interrupt-in endpoint descriptors (bnc#970955). - CVE-2016-2188: The iowarrior_probe function in drivers/usb/misc/iowarrior.c in the Linux kernel allowed physically proximate attackers to cause a denial of service (NULL pointer dereference and system crash) via a crafted endpoints value in a USB device descriptor (bnc#970956). - CVE-2016-3138: The acm_probe function in drivers/usb/class/cdc-acm.c in the Linux kernel allowed physically proximate attackers to cause a denial of service (NULL pointer dereference and system crash) via a USB device without both a control and a data endpoint descriptor (bnc#970911). - CVE-2016-3137: drivers/usb/serial/cypress_m8.c in the Linux kernel allowed physically proximate attackers to cause a denial of service (NULL pointer dereference and system crash) via a USB device without both an interrupt-in and an interrupt-out endpoint descriptor, related to the cypress_generic_port_probe and cypress_open functions (bnc#970970). -

    title openSUSE Security Update : the Linux Kernel (openSUSE-2016-1015)
  • NASL family Oracle Linux Local Security Checks
    NASL id ORACLELINUX_ELSA-2018-1854.NASL
    description From Red Hat Security Advisory 2018:1854 : An update for kernel is now available for Red Hat Enterprise Linux 6. 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, PowerPC) * kernel: net/packet: overflow in check for priv area size (CVE-2017-7308) * kernel: AIO interface didn't use rw_verify_area() for checking mandatory locking on files and size of access (CVE-2012-6701) * kernel: AIO write triggers integer overflow in some protocols (CVE-2015-8830) * kernel: NULL pointer dereference via keyctl (CVE-2016-8650) * kernel: ping socket / AF_LLC connect() sin_family race (CVE-2017-2671) * kernel: Race condition between multiple sys_perf_event_open() calls (CVE-2017-6001) * kernel: Incorrect error handling in the set_mempolicy and mbind compat syscalls in mm/mempolicy.c (CVE-2017-7616) * kernel: mm subsystem does not properly enforce the CONFIG_STRICT_DEVMEM protection mechanism (CVE-2017-7889) * kernel: Double free in the inet_csk_clone_lock function in net/ipv4/ inet_connection_sock.c (CVE-2017-8890) * kernel: net: sctp_v6_create_accept_sk function mishandles inheritance (CVE-2017-9075) * kernel: net: IPv6 DCCP implementation mishandles inheritance (CVE-2017-9076) * kernel: net: tcp_v6_syn_recv_sock function mishandles inheritance (CVE-2017-9077) * kernel: memory leak when merging buffers in SCSI IO vectors (CVE-2017-12190) * kernel: vfs: BUG in truncate_inode_pages_range() and fuse client (CVE-2017-15121) * kernel: Race condition in drivers/md/dm.c:dm_get_from_kobject() allows local users to cause a denial of service (CVE-2017-18203) * kernel: a NULL pointer dereference in net/dccp/output.c:dccp_write_xmit() leads to a system crash (CVE-2018-1130) * kernel: Missing length check of payload in net/sctp/ sm_make_chunk.c:_sctp_make_chunk() function allows denial of service (CVE-2018-5803) 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; Vitaly Mayatskih for reporting CVE-2017-12190; and Evgenii Shatokhin (Virtuozzo Team) for reporting CVE-2018-1130. The CVE-2017-15121 issue was discovered by Miklos Szeredi (Red Hat).

    description Several vulnerabilities have been discovered in the Linux kernel that may lead to a privilege escalation, denial of service, information leak or data loss. - CVE-2013-4312, CVE-2016-2847 Tetsuo Handa discovered that users can use pipes queued on local (Unix) sockets to allocate an unfair share of kernel memory, leading to denial-of-service (resource exhaustion). This issue was previously mitigated for the stable suite by limiting the total number of files queued by each user on local sockets. The new kernel version in both suites includes that mitigation plus limits on the total size of pipe buffers allocated for each user. - CVE-2015-7566 Ralf Spenneberg of OpenSource Security reported that the visor driver crashes when a specially crafted USB device without bulk-out endpoint is detected. - CVE-2015-8767 An SCTP denial-of-service was discovered which can be triggered by a local attacker during a heartbeat timeout event after the 4-way handshake. - CVE-2015-8785 It was discovered that local users permitted to write to a file on a FUSE filesystem could cause a denial of service (unkillable loop in the kernel). - CVE-2015-8812 A flaw was found in the iw_cxgb3 Infiniband driver. Whenever it could not send a packet because the network was congested, it would free the packet buffer but later attempt to send the packet again. This use-after-free could result in a denial of service (crash or hang), data loss or privilege escalation. - CVE-2015-8816 A use-after-free vulnerability was discovered in the USB hub driver. This may be used by a physically present user for privilege escalation. - CVE-2015-8830 Ben Hawkes of Google Project Zero reported that the AIO interface permitted reading or writing 2 GiB of data or more in a single chunk, which could lead to an integer overflow when applied to certain filesystems, socket or device types. The full security impact has not been evaluated. - CVE-2016-0723 A use-after-free vulnerability was discovered in the TIOCGETD ioctl. A local attacker could use this flaw for denial-of-service. - CVE-2016-0774 It was found that the fix for CVE-2015-1805 in kernel versions older than Linux 3.16 did not correctly handle the case of a partially failed atomic read. A local, unprivileged user could use this flaw to crash the system or leak kernel memory to user space. - CVE-2016-2069 Andy Lutomirski discovered a race condition in flushing of the TLB when switching tasks on an x86 system. On an SMP system this could possibly lead to a crash, information leak or privilege escalation. - CVE-2016-2384 Andrey Konovalov found that a crafted USB MIDI device with an invalid USB descriptor could trigger a double-free. This may be used by a physically present user for privilege escalation. - CVE-2016-2543 Dmitry Vyukov found that the core sound sequencer driver (snd-seq) lacked a necessary check for a NULL pointer, allowing a user with access to a sound sequencer device to cause a denial-of service (crash). - CVE-2016-2544, CVE-2016-2546, CVE-2016-2547, CVE-2016-2548 Dmitry Vyukov found various race conditions in the sound subsystem (ALSA)'s management of timers. A user with access to sound devices could use these to cause a denial-of-service (crash or hang) or possibly for privilege escalation. - CVE-2016-2545 Dmitry Vyukov found a flaw in list manipulation in the sound subsystem (ALSA)'s management of timers. A user with access to sound devices could use this to cause a denial-of-service (crash or hang) or possibly for privilege escalation. - CVE-2016-2549 Dmitry Vyukov found a potential deadlock in the sound subsystem (ALSA)'s use of high resolution timers. A user with access to sound devices could use this to cause a denial-of-service (hang). - CVE-2016-2550 The original mitigation of CVE-2013-4312, limiting the total number of files a user could queue on local sockets, was flawed. A user given a local socket opened by another user, for example through the systemd socket activation mechanism, could make use of the other user's quota, again leading to a denial-of-service (resource exhaustion). This is fixed by accounting queued files to the sender rather than the socket opener.

    description An update for kernel is now available for Red Hat Enterprise Linux 6. 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, PowerPC) * kernel: net/packet: overflow in check for priv area size (CVE-2017-7308) * kernel: AIO interface didn't use rw_verify_area() for checking mandatory locking on files and size of access (CVE-2012-6701) * kernel: AIO write triggers integer overflow in some protocols (CVE-2015-8830) * kernel: NULL pointer dereference via keyctl (CVE-2016-8650) * kernel: ping socket / AF_LLC connect() sin_family race (CVE-2017-2671) * kernel: Race condition between multiple sys_perf_event_open() calls (CVE-2017-6001) * kernel: Incorrect error handling in the set_mempolicy and mbind compat syscalls in mm/mempolicy.c (CVE-2017-7616) * kernel: mm subsystem does not properly enforce the CONFIG_STRICT_DEVMEM protection mechanism (CVE-2017-7889) * kernel: Double free in the inet_csk_clone_lock function in net/ipv4/ inet_connection_sock.c (CVE-2017-8890) * kernel: net: sctp_v6_create_accept_sk function mishandles inheritance (CVE-2017-9075) * kernel: net: IPv6 DCCP implementation mishandles inheritance (CVE-2017-9076) * kernel: net: tcp_v6_syn_recv_sock function mishandles inheritance (CVE-2017-9077) * kernel: memory leak when merging buffers in SCSI IO vectors (CVE-2017-12190) * kernel: vfs: BUG in truncate_inode_pages_range() and fuse client (CVE-2017-15121) * kernel: Race condition in drivers/md/dm.c:dm_get_from_kobject() allows local users to cause a denial of service (CVE-2017-18203) * kernel: a NULL pointer dereference in net/dccp/output.c:dccp_write_xmit() leads to a system crash (CVE-2018-1130) * kernel: Missing length check of payload in net/sctp/ sm_make_chunk.c:_sctp_make_chunk() function allows denial of service (CVE-2018-5803) 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; Vitaly Mayatskih for reporting CVE-2017-12190; and Evgenii Shatokhin (Virtuozzo Team) for reporting CVE-2018-1130.

  • NASL family Virtuozzo Local Security Checks
    NASL id VIRTUOZZO_VZA-2018-041.NASL
    description According to the versions of the parallels-server-bm-release / vzkernel / etc packages installed, the Virtuozzo installation on the remote host is affected by the following vulnerabilities : - The do_get_mempolicy() function in 'mm/mempolicy.c' in the Linux kernel allows local users to hit a use-after-free bug via crafted system calls and thus cause a denial of service (DoS) or possibly have unspecified other impact. Due to the nature of the flaw, privilege escalation cannot be fully ruled out. - It was found that AIO interface didn't use the proper rw_verify_area() helper function with extended functionality, for example, mandatory locking on the file. Also rw_verify_area() makes extended checks, for example, that the size of the access doesn't cause overflow of the provided offset limits. This integer overflow in fs/aio.c in the Linux kernel before 3.4.1 allows local users to cause a denial of service or possibly have unspecified other impact via a large AIO iovec. - Integer overflow in the aio_setup_single_vector function in fs/aio.c in the Linux kernel 4.0 allows local users to cause a denial of service or possibly have unspecified other impact via a large AIO iovec. NOTE: this vulnerability exists because of a CVE-2012-6701 regression. - A flaw was found in the Linux kernel key management subsystem in which a local attacker could crash the kernel or corrupt the stack and additional memory (denial of service) by supplying a specially crafted RSA key. This flaw panics the machine during the verification of the RSA key. - A race condition leading to a NULL pointer dereference was found in the Linux kernel's Link Layer Control implementation. A local attacker with access to ping sockets could use this flaw to crash the system. - It was found that the original fix for CVE-2016-6786 was incomplete. There exist a race between two concurrent sys_perf_event_open() calls when both try and move the same pre-existing software group into a hardware context. - Incorrect error handling in the set_mempolicy() and mbind() compat syscalls in 'mm/mempolicy.c' in the Linux kernel allows local users to obtain sensitive information from uninitialized stack data by triggering failure of a certain bitmap operation. - The mm subsystem in the Linux kernel through 4.10.10 does not properly enforce the CONFIG_STRICT_DEVMEM protection mechanism, which allows local users to read or write to kernel memory locations in the first megabyte (and bypass slab-allocation access restrictions) via an application that opens the /dev/mem file, related to arch/x86/mm/init.c and drivers/char/mem.c. - It was found that in the Linux kernel through v4.14-rc5, bio_map_user_iov() and bio_unmap_user() in 'block/bio.c' do unbalanced pages refcounting if IO vector has small consecutive buffers belonging to the same page. bio_add_pc_page() merges them into one, but the page reference is never dropped, causing a memory leak and possible system lockup due to out-of-memory condition. - The Linux kernel, before version 4.14.3, is vulnerable to a denial of service in drivers/md/dm.c:dm_get_from_kobject() which can be caused by local users leveraging a race condition with __dm_destroy() during creation and removal of DM devices. Only privileged local users (with CAP_SYS_ADMIN capability) can directly perform the ioctl operations for dm device creation and removal and this would typically be outside the direct control of the unprivileged attacker. - An error in the '_sctp_make_chunk()' function (net/sctp/sm_make_chunk.c) when handling SCTP, packet length can be exploited by a malicious local user to cause a kernel crash and a DoS. - Memory leak in the sas_smp_get_phy_events function in drivers/scsi/libsas/sas_expander.c in the Linux kernel allows local users to cause a denial of service (kernel memory exhaustion) via multiple read accesses to files in the /sys/class/sas_phy directory. 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.
