  • Leveraging Race Conditions
    This attack targets a race condition occurring when multiple processes access and manipulate the same resource concurrently and the outcome of the execution depends on the particular order in which the access takes place. The attacker can leverage a race condition by "running the race", modifying the resource and modifying the normal execution flow. For instance a race condition can occur while accessing a file, the attacker can trick the system by replacing the original file with his version and cause the system to read the malicious file.
  • Leveraging Time-of-Check and Time-of-Use (TOCTOU) Race Conditions
    This attack targets a race condition occurring between the time of check (state) for a resource and the time of use of a resource. The typical example is the file access. The attacker can leverage a file access race condition by "running the race", meaning that he would modify the resource between the first time the target program accesses the file and the time the target program uses the file. During that period of time, the attacker could do something such as replace the file and cause an escalation of privilege.

    description This update fixes the CVEs described below. CVE-2016-3857 Chiachih Wu reported two bugs in the ARM OABI compatibility layer that can be used by local users for privilege escalation. The OABI compatibility layer is enabled in all kernel flavours for armel and armhf. CVE-2016-4470 Wade Mealing of the Red Hat Product Security Team reported that in some error cases the KEYS subsystem will dereference an uninitialised pointer. A local user can use the keyctl() system call for denial of service (crash) or possibly for privilege escalation. CVE-2016-5696 Yue Cao, Zhiyun Qian, Zhongjie Wang, Tuan Dao, and Srikanth V. Krishnamurthy of the University of California, Riverside; and Lisa M. Marvel of the United States Army Research Laboratory discovered that Linux's implementation of the TCP Challenge ACK feature results in a side channel that can be used to find TCP connections between specific IP addresses, and to inject messages into those connections. Where a service is made available through TCP, this may allow remote attackers to impersonate another connected user to the server or to impersonate the server to another connected user. In case the service uses a protocol with message authentication (e.g. TLS or SSH), this vulnerability only allows denial of service (connection failure). An attack takes tens of seconds, so short-lived TCP connections are also unlikely to be vulnerable. This may be mitigated by increasing the rate limit for TCP Challenge ACKs so that it is never exceeded: sysctl net.ipv4.tcp_challenge_ack_limit=1000000000 CVE-2016-5829 Several heap-based buffer overflow vulnerabilities were found in the hiddev driver, allowing a local user with access to a HID device to cause a denial of service or potentially escalate their privileges. CVE-2016-6136 Pengfei Wang discovered that the audit subsystem has a 'double-fetch' or 'TOCTTOU' bug in its handling of special characters in the name of an executable. Where audit logging of execve() is enabled, this allows a local user to generate misleading log messages. CVE-2016-6480 Pengfei Wang discovered that the aacraid driver for Adaptec RAID controllers has a 'double-fetch' or 'TOCTTOU' bug in its validation of 'FIB' messages passed through the ioctl() system call. This has no practical security impact in current Debian releases. CVE-2016-6828 Marco Grassi reported a 'use-after-free' bug in the TCP implementation, which can be triggered by local users. The security impact is unclear, but might include denial of service or privilege escalation. CVE-2016-7118 Marcin Szewczyk reported that calling fcntl() on a file descriptor for a directory on an aufs filesystem would result in am 'oops'. This allows local users to cause a denial of service. This is a Debian-specific regression introduced in version 3.2.81-1. For Debian 7 'Wheezy', these problems have been fixed in version 3.2.81-2. This version also fixes a build failure (bug #827561) for custom kernels with CONFIG_MODULES disabled, a regression in version 3.2.81-1. It also updates the PREEMPT_RT featureset to version 3.2.81-rt117. For Debian 8 'Jessie', CVE-2016-3857 has no impact; CVE-2016-4470 and CVE-2016-5829 were fixed in linux version 3.16.7-ckt25-2+deb8u3 or earlier; and the remaining issues are fixed in version 3.16.36-1+deb8u1. 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 The openSUSE 13.1 kernel was updated to 3.12.67 to receive various security and bugfixes. The following security bugs were fixed : - CVE-2013-5634: arch/arm/kvm/arm.c in the Linux kernel on the ARM platform, when KVM is used, allowed host OS users to cause a denial of service (NULL pointer dereference, OOPS, and host OS crash) or possibly have unspecified other impact by omitting vCPU initialization before a KVM_GET_REG_LIST ioctl call. (bsc#994758) - CVE-2016-2069: Race condition in arch/x86/mm/tlb.c in the Linux kernel allowed local users to gain privileges by triggering access to a paging structure by a different CPU (bnc#963767). - CVE-2016-7042: The proc_keys_show function in security/keys/proc.c in the Linux kernel used an incorrect buffer size for certain timeout data, which allowed local users to cause a denial of service (stack memory corruption and panic) by reading the /proc/keys file (bnc#1004517). - CVE-2016-7097: The filesystem implementation in the Linux kernel preserved the setgid bit during a setxattr call, which allowed local users to gain group privileges by leveraging the existence of a setgid program with restrictions on execute permissions (bnc#995968). - CVE-2015-8956: The rfcomm_sock_bind function in net/bluetooth/rfcomm/sock.c in the Linux kernel allowed local users to obtain sensitive information or cause a denial of service (NULL pointer dereference) via vectors involving a bind system call on a Bluetooth RFCOMM socket (bnc#1003925). - CVE-2016-8658: Stack-based buffer overflow in the brcmf_cfg80211_start_ap function in drivers/net/wireless/broadcom/brcm80211/brcmfmac/cfg8021 1.c in the Linux kernel allowed local users to cause a denial of service (system crash) or possibly have unspecified other impact via a long SSID Information Element in a command to a Netlink socket (bnc#1004462). - CVE-2016-7425: The arcmsr_iop_message_xfer function in drivers/scsi/arcmsr/arcmsr_hba.c in the Linux kernel did not restrict a certain length field, which allowed local users to gain privileges or cause a denial of service (heap-based buffer overflow) via an ARCMSR_MESSAGE_WRITE_WQBUFFER control code (bnc#999932). - CVE-2016-6327: drivers/infiniband/ulp/srpt/ib_srpt.c in the Linux kernel allowed local users to cause a denial of service (NULL pointer dereference and system crash) by using an ABORT_TASK command to abort a device write operation (bnc#994748). - CVE-2016-6828: The tcp_check_send_head function in include/net/tcp.h in the Linux kernel did not properly maintain certain SACK state after a failed data copy, which allowed local users to cause a denial of service (tcp_xmit_retransmit_queue use-after-free and system crash) via a crafted SACK option (bnc#994296). - CVE-2016-5696: net/ipv4/tcp_input.c in the Linux kernel did not properly determine the rate of challenge ACK segments, which made it easier for remote attackers to hijack TCP sessions via a blind in-window attack (bnc#989152). - CVE-2016-6130: Race condition in the sclp_ctl_ioctl_sccb function in drivers/s390/char/sclp_ctl.c in the Linux kernel allowed local users to obtain sensitive information from kernel memory by changing a certain length value, aka a 'double fetch' vulnerability (bnc#987542). - CVE-2016-6480: Race condition in the ioctl_send_fib function in drivers/scsi/aacraid/commctrl.c in the Linux kernel allowed local users to cause a denial of service (out-of-bounds access or system crash) by changing a certain size value, aka a 'double fetch' vulnerability (bnc#991608).

    title openSUSE Security Update : the Linux Kernel (openSUSE-2016-1410)
  • NASL family SuSE Local Security Checks
    NASL id SUSE_SU-2016-2912-1.NASL
    description The SUSE Linux Enterprise 12 kernel was updated to 3.12.67 to receive various security and bugfixes. The following security bugs were fixed : - CVE-2016-7042: The proc_keys_show function in security/keys/proc.c in the Linux kernel used an incorrect buffer size for certain timeout data, which allowed local users to cause a denial of service (stack memory corruption and panic) by reading the /proc/keys file (bsc#1004517). - CVE-2016-7097: The filesystem implementation in the Linux kernel preserved the setgid bit during a setxattr call, which allowed local users to gain group privileges by leveraging the existence of a setgid program with restrictions on execute permissions (bsc#995968). - CVE-2015-8956: The rfcomm_sock_bind function in net/bluetooth/rfcomm/sock.c in the Linux kernel allowed local users to obtain sensitive information or cause a denial of service (NULL pointer dereference) via vectors involving a bind system call on a Bluetooth RFCOMM socket (bnc#1003925). - CVE-2016-5696: net/ipv4/tcp_input.c in the Linux kernel did not properly determine the rate of challenge ACK segments, which made it easier for man-in-the-middle attackers to hijack TCP sessions via a blind in-window attack (bnc#989152). - CVE-2016-6130: Race condition in the sclp_ctl_ioctl_sccb function in drivers/s390/char/sclp_ctl.c in the Linux kernel allowed local users to obtain sensitive information from kernel memory by changing a certain length value, aka a 'double fetch' vulnerability (bnc#987542). - CVE-2016-6327: drivers/infiniband/ulp/srpt/ib_srpt.c in the Linux kernel allowed local users to cause a denial of service (NULL pointer dereference and system crash) by using an ABORT_TASK command to abort a device write operation (bnc#994748). - CVE-2016-6480: Race condition in the ioctl_send_fib function in drivers/scsi/aacraid/commctrl.c in the Linux kernel allowed local users to cause a denial of service (out-of-bounds access or system crash) by changing a certain size value, aka a 'double fetch' vulnerability (bnc#991608). - CVE-2016-6828: The tcp_check_send_head function in include/net/tcp.h in the Linux kernel did not properly maintain certain SACK state after a failed data copy, which allowed local users to cause a denial of service (tcp_xmit_retransmit_queue use-after-free and system crash) via a crafted SACK option (bnc#994296). - CVE-2016-7425: The arcmsr_iop_message_xfer function in drivers/scsi/arcmsr/arcmsr_hba.c in the Linux kernel did not restrict a certain length field, which allowed local users to gain privileges or cause a denial of service (heap-based buffer overflow) via an ARCMSR_MESSAGE_WRITE_WQBUFFER control code (bnc#999932). - CVE-2016-8658: Stack-based buffer overflow in the brcmf_cfg80211_start_ap function in drivers/net/wireless/broadcom/brcm80211/brcmfmac/cfg8021 1.c in the Linux kernel allowed local users to cause a denial of service (system crash) or possibly have unspecified other impact via a long SSID Information Element in a command to a Netlink socket (bnc#1004462). - CVE-2016-8666: The IP stack in the Linux kernel allowed remote attackers to cause a denial of service (stack consumption and panic) or possibly have unspecified other impact by triggering use of the GRO path for packets with tunnel stacking, as demonstrated by interleaved IPv4 headers and GRE headers, a related issue to CVE-2016-7039 (bsc#1001486). 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 openSUSE Security Update : the Linux Kernel (openSUSE-2016-1227) (Dirty COW)
  • NASL family Virtuozzo Local Security Checks
    NASL id VIRTUOZZO_VZA-2017-025.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 : - A flaw was found in the Linux kernel's handling of packets with the URG flag. Applications using the splice() and tcp_splice_read() functionality can allow a remote attacker to force the kernel to enter a condition in which it can loop indefinitely. - It was discovered that a remote attacker could leverage the generation of IPv6 atomic fragments to trigger the use of fragmentation in an arbitrary IPv6 flow (in scenarios in which actual fragmentation of packets is not needed) and could subsequently perform any type of a fragmentation-based attack against legacy IPv6 nodes that do not implement RFC6946. - It was found that the blk_rq_map_user_iov() function in the Linux kernel's block device implementation did not properly restrict the type of iterator, which could allow a local attacker to read or write to arbitrary kernel memory locations or cause a denial of service (use-after-free) by leveraging write access to a /dev/sg device. - A flaw was found in the Linux kernel's implementation of the SCTP protocol. A remote attacker could trigger an out-of-bounds read with an offset of up to 64kB potentially causing the system to crash. - A flaw was found in the Linux networking subsystem where a local attacker with CAP_NET_ADMIN capabilities could cause an out-of-bounds memory access by creating a smaller-than-expected ICMP header and sending to its destination via sendto(). - It was found that when file permissions were modified via chmod and the user modifying them was not in the owning group or capable of CAP_FSETID, the setgid bit would be cleared. Setting a POSIX ACL via setxattr sets the file permissions as well as the new ACL, but doesn't clear the setgid bit in a similar way. This could allow a local user to gain group privileges via certain setgid applications. - It was found that when the gcc stack protector was enabled, reading the /proc/keys file could cause a panic in the Linux kernel due to stack corruption. This happened because an incorrect buffer size was used to hold a 64-bit timeout value rendered as weeks. - A race condition flaw was found in the ioctl_send_fib() function in the Linux kernel's aacraid implementation. A local attacker could use this flaw to cause a denial of service (out-of-bounds access or system crash) by changing a certain size value. - When creating audit records for parameters to executed children processes, an attacker can convince the Linux kernel audit subsystem can create corrupt records which may allow an attacker to misrepresent or evade logging of executing commands. - A flaw was discovered in the way the Linux kernel dealt with paging structures. When the kernel invalidated a paging structure that was not in use locally, it could, in principle, race against another CPU that is switching to a process that uses the paging structure in question. A local user could use a thread running with a stale cached virtual->physical translation to potentially escalate their privileges if the translation in question were writable and the physical page got reused for something critical (for example, a page table). - A flaw was found in the USB-MIDI Linux kernel driver: a double-free error could be triggered for the 'umidi' object. An attacker with physical access to the system could use this flaw to escalate their privileges. 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 The SUSE Linux Enterprise 11 SP4 kernel was updated to receive various security and bugfixes. For the PowerPC64 a new 'bigmem' flavor has been added to support big Power machines. (FATE#319026) The following security bugs were fixed : - CVE-2016-7042: The proc_keys_show function in security/keys/proc.c in the Linux kernel, when the GNU Compiler Collection (gcc) stack protector is enabled, uses an incorrect buffer size for certain timeout data, which allowed local users to cause a denial of service (stack memory corruption and panic) by reading the /proc/keys file (bnc#1004517). - CVE-2016-7097: The filesystem implementation in the Linux kernel preserves the setgid bit during a setxattr call, which allowed local users to gain group privileges by leveraging the existence of a setgid program with restrictions on execute permissions (bnc#995968). - CVE-2015-8956: The rfcomm_sock_bind function in net/bluetooth/rfcomm/sock.c in the Linux kernel allowed local users to obtain sensitive information or cause a denial of service (NULL pointer dereference) via vectors involving a bind system call on a Bluetooth RFCOMM socket (bnc#1003925). - CVE-2016-7117: Use-after-free vulnerability in the __sys_recvmmsg function in net/socket.c in the Linux kernel allowed remote attackers to execute arbitrary code via vectors involving a recvmmsg system call that is mishandled during error processing (bnc#1003077). - CVE-2016-0823: The pagemap_open function in fs/proc/task_mmu.c in the Linux kernel allowed local users to obtain sensitive physical-address information by reading a pagemap file, aka Android internal bug 25739721 (bnc#994759). - CVE-2016-7425: The arcmsr_iop_message_xfer function in drivers/scsi/arcmsr/arcmsr_hba.c in the Linux kernel did not restrict a certain length field, which allowed local users to gain privileges or cause a denial of service (heap-based buffer overflow) via an ARCMSR_MESSAGE_WRITE_WQBUFFER control code (bnc#999932). - CVE-2016-3841: The IPv6 stack in the Linux kernel mishandled options data, which allowed local users to gain privileges or cause a denial of service (use-after-free and system crash) via a crafted sendmsg system call (bnc#992566). - CVE-2016-6828: The tcp_check_send_head function in include/net/tcp.h in the Linux kernel did not properly maintain certain SACK state after a failed data copy, which allowed local users to cause a denial of service (tcp_xmit_retransmit_queue use-after-free and system crash) via a crafted SACK option (bnc#994296). - CVE-2016-5696: net/ipv4/tcp_input.c in the Linux kernel did not properly determine the rate of challenge ACK segments, which made it easier for remote attackers to hijack TCP sessions via a blind in-window attack (bnc#989152). - CVE-2016-6480: Race condition in the ioctl_send_fib function in drivers/scsi/aacraid/commctrl.c in the Linux kernel allowed local users to cause a denial of service (out-of-bounds access or system crash) by changing a certain size value, aka a 'double fetch' vulnerability (bnc#991608). - CVE-2016-4998: The IPT_SO_SET_REPLACE setsockopt implementation in the netfilter subsystem in the Linux kernel allowed local users to cause a denial of service (out-of-bounds read) or possibly obtain sensitive information from kernel heap memory by leveraging in-container root access to provide a crafted offset value that leads to crossing a ruleset blob boundary (bnc#986365). - CVE-2015-7513: arch/x86/kvm/x86.c in the Linux kernel did not reset the PIT counter values during state restoration, which allowed guest OS users to cause a denial of service (divide-by-zero error and host OS crash) via a zero value, related to the kvm_vm_ioctl_set_pit and kvm_vm_ioctl_set_pit2 functions (bnc#960689). - CVE-2013-4312: The Linux kernel allowed local users to bypass file-descriptor limits and cause a denial of service (memory consumption) by sending each descriptor over a UNIX socket before closing it, related to net/unix/af_unix.c and net/unix/garbage.c (bnc#839104 bsc#922947 bsc#968014).

  • NASL family Debian Local Security Checks
    NASL id DEBIAN_DSA-3659.NASL
    description Several vulnerabilities have been discovered in the Linux kernel that may lead to a privilege escalation, denial of service or have other impacts. - CVE-2016-5696 Yue Cao, Zhiyun Qian, Zhongjie Wang, Tuan Dao, and Srikanth V. Krishnamurthy of the University of California, Riverside; and Lisa M. Marvel of the United States Army Research Laboratory discovered that Linux's implementation of the TCP Challenge ACK feature results in a side channel that can be used to find TCP connections between specific IP addresses, and to inject messages into those connections. Where a service is made available through TCP, this may allow remote attackers to impersonate another connected user to the server or to impersonate the server to another connected user. In case the service uses a protocol with message authentication (e.g. TLS or SSH), this vulnerability only allows denial of service (connection failure). An attack takes tens of seconds, so short-lived TCP connections are also unlikely to be vulnerable. This may be mitigated by increasing the rate limit for TCP Challenge ACKs so that it is never exceeded: sysctl net.ipv4.tcp_challenge_ack_limit=1000000000 - CVE-2016-6136 Pengfei Wang discovered that the audit subsystem has a 'double-fetch' or 'TOCTTOU' bug in its handling of special characters in the name of an executable. Where audit logging of execve() is enabled, this allows a local user to generate misleading log messages. - CVE-2016-6480 Pengfei Wang discovered that the aacraid driver for Adaptec RAID controllers has a 'double-fetch' or 'TOCTTOU' bug in its validation of 'FIB' messages passed through the ioctl() system call. This has no practical security impact in current Debian releases. - CVE-2016-6828 Marco Grassi reported a 'use-after-free' bug in the TCP implementation, which can be triggered by local users. The security impact is unclear, but might include denial of service or privilege escalation.

  • NASL family SuSE Local Security Checks
    NASL id SUSE_SU-2017-0471-1.NASL
    description The SUSE Linux Enterprise 12 GA LTSS kernel was updated to 3.12.61 to receive various security and bugfixes. The following feature was implemented : - The ext2 filesystem got reenabled and supported to allow support for 'XIP' (Execute In Place) (FATE#320805). The following security bugs were fixed : - CVE-2017-5551: The tmpfs filesystem implementation in the Linux kernel preserved the setgid bit during a setxattr call, which allowed local users to gain group privileges by leveraging the existence of a setgid program with restrictions on execute permissions (bsc#1021258). - CVE-2016-7097: The filesystem implementation in the Linux kernel preserved the setgid bit during a setxattr call, which allowed local users to gain group privileges by leveraging the existence of a setgid program with restrictions on execute permissions (bnc#995968). - CVE-2017-2583: A Linux kernel built with the Kernel-based Virtual Machine (CONFIG_KVM) support was vulnerable to an incorrect segment selector(SS) value error. A user/process inside guest could have used this flaw to crash the guest resulting in DoS or potentially escalate their privileges inside guest. (bsc#1020602). - CVE-2017-2584: arch/x86/kvm/emulate.c in the Linux kernel allowed local users to obtain sensitive information from kernel memory or cause a denial of service (use-after-free) via a crafted application that leverages instruction emulation for fxrstor, fxsave, sgdt, and sidt (bnc#1019851). - CVE-2016-10088: The sg implementation in the Linux kernel did not properly restrict write operations in situations where the KERNEL_DS option is set, which allowed local users to read or write to arbitrary kernel memory locations or cause a denial of service (use-after-free) by leveraging access to a /dev/sg device, related to block/bsg.c and drivers/scsi/sg.c. NOTE: this vulnerability exists because of an incomplete fix for CVE-2016-9576 (bnc#1017710). - CVE-2016-8645: The TCP stack in the Linux kernel mishandled skb truncation, which allowed local users to cause a denial of service (system crash) via a crafted application that made sendto system calls, related to net/ipv4/tcp_ipv4.c and net/ipv6/tcp_ipv6.c (bnc#1009969). - CVE-2016-8399: An elevation of privilege vulnerability in the kernel networking subsystem could enable a local malicious application to execute arbitrary code within the context of the kernel. This issue is rated as Moderate because it first requires compromising a privileged process and current compiler optimizations restrict access to the vulnerable code. Product: Android. Versions: Kernel-3.10, Kernel-3.18. Android ID: A-31349935 (bnc#1014746). - CVE-2016-9806: Race condition in the netlink_dump function in net/netlink/af_netlink.c in the Linux kernel allowed local users to cause a denial of service (double free) or possibly have unspecified other impact via a crafted application that made sendmsg system calls, leading to a free operation associated with a new dump that started earlier than anticipated (bnc#1013540). - CVE-2016-9756: arch/x86/kvm/emulate.c in the Linux kernel did not properly initialize Code Segment (CS) in certain error cases, which allowed local users to obtain sensitive information from kernel stack memory via a crafted application (bnc#1013038). -
