CWE CWE-119
CAPEC
  • Buffer Overflow via Environment Variables
    This attack pattern involves causing a buffer overflow through manipulation of environment variables. Once the attacker finds that they can modify an environment variable, they may try to overflow associated buffers. This attack leverages implicit trust often placed in environment variables.
  • Overflow Buffers
    Buffer Overflow attacks target improper or missing bounds checking on buffer operations, typically triggered by input injected by an attacker. As a consequence, an attacker is able to write past the boundaries of allocated buffer regions in memory, causing a program crash or potentially redirection of execution as per the attackers' choice.
  • Client-side Injection-induced Buffer Overflow
    This type of attack exploits a buffer overflow vulnerability in targeted client software through injection of malicious content from a custom-built hostile service.
  • Filter Failure through Buffer Overflow
    In this attack, the idea is to cause an active filter to fail by causing an oversized transaction. An attacker may try to feed overly long input strings to the program in an attempt to overwhelm the filter (by causing a buffer overflow) and hoping that the filter does not fail securely (i.e. the user input is let into the system unfiltered).
  • MIME Conversion
    An attacker exploits a weakness in the MIME conversion routine to cause a buffer overflow and gain control over the mail server machine. The MIME system is designed to allow various different information formats to be interpreted and sent via e-mail. Attack points exist when data are converted to MIME compatible format and back.
  • Overflow Binary Resource File
    An attack of this type exploits a buffer overflow vulnerability in the handling of binary resources. Binary resources may include music files like MP3, image files like JPEG files, and any other binary file. These attacks may pass unnoticed to the client machine through normal usage of files, such as a browser loading a seemingly innocent JPEG file. This can allow the attacker access to the execution stack and execute arbitrary code in the target process. This attack pattern is a variant of standard buffer overflow attacks using an unexpected vector (binary files) to wrap its attack and open up a new attack vector. The attacker is required to either directly serve the binary content to the victim, or place it in a locale like a MP3 sharing application, for the victim to download. The attacker then is notified upon the download or otherwise locates the vulnerability opened up by the buffer overflow.
  • Buffer Overflow via Symbolic Links
    This type of attack leverages the use of symbolic links to cause buffer overflows. An attacker can try to create or manipulate a symbolic link file such that its contents result in out of bounds data. When the target software processes the symbolic link file, it could potentially overflow internal buffers with insufficient bounds checking.
  • Overflow Variables and Tags
    This type of attack leverages the use of tags or variables from a formatted configuration data to cause buffer overflow. The attacker crafts a malicious HTML page or configuration file that includes oversized strings, thus causing an overflow.
  • Buffer Overflow via Parameter Expansion
    In this attack, the target software is given input that the attacker knows will be modified and expanded in size during processing. This attack relies on the target software failing to anticipate that the expanded data may exceed some internal limit, thereby creating a buffer overflow.
  • Buffer Overflow in an API Call
    This attack targets libraries or shared code modules which are vulnerable to buffer overflow attacks. An attacker who has access to an API may try to embed malicious code in the API function call and exploit a buffer overflow vulnerability in the function's implementation. All clients that make use of the code library thus become vulnerable by association. This has a very broad effect on security across a system, usually affecting more than one software process.
  • Buffer Overflow in Local Command-Line Utilities
    This attack targets command-line utilities available in a number of shells. An attacker can leverage a vulnerability found in a command-line utility to escalate privilege to root.

  • NASL family Mandriva Local Security Checks
    NASL id MANDRIVA_MDVSA-2015-027.NASL
    description Multiple vulnerabilities has been found and corrected in the Linux kernel : The SCTP implementation in the Linux kernel before 3.17.4 allows remote attackers to cause a denial of service (memory consumption) by triggering a large number of chunks in an association's output queue, as demonstrated by ASCONF probes, related to net/sctp/inqueue.c and net/sctp/sm_statefuns.c (CVE-2014-3688=. Buffer overflow in net/ceph/auth_x.c in Ceph, as used in the Linux kernel before 3.16.3, allows remote attackers to cause a denial of service (memory corruption and panic) or possibly have unspecified other impact via a long unencrypted auth ticket (CVE-2014-6416). net/ceph/auth_x.c in Ceph, as used in the Linux kernel before 3.16.3, does not properly consider the possibility of kmalloc failure, which allows remote attackers to cause a denial of service (system crash) or possibly have unspecified other impact via a long unencrypted auth ticket (CVE-2014-6417). net/ceph/auth_x.c in Ceph, as used in the Linux kernel before 3.16.3, does not properly validate auth replies, which allows remote attackers to cause a denial of service (system crash) or possibly have unspecified other impact via crafted data from the IP address of a Ceph Monitor (CVE-2014-6418). The sctp_process_param function in net/sctp/sm_make_chunk.c in the SCTP implementation in the Linux kernel before 3.17.4, when ASCONF is used, allows remote attackers to cause a denial of service (NULL pointer dereference and system crash) via a malformed INIT chunk (CVE-2014-7841). Race condition in arch/x86/kvm/x86.c in the Linux kernel before 3.17.4 allows guest OS users to cause a denial of service (guest OS crash) via a crafted application that performs an MMIO transaction or a PIO transaction to trigger a guest userspace emulation error report, a similar issue to CVE-2010-5313 (CVE-2014-7842). arch/x86/kernel/tls.c in the Thread Local Storage (TLS) implementation in the Linux kernel through 3.18.1 allows local users to bypass the espfix protection mechanism, and consequently makes it easier for local users to bypass the ASLR protection mechanism, via a crafted application that makes a set_thread_area system call and later reads a 16-bit value (CVE-2014-8133). Stack-based buffer overflow in the ttusbdecfe_dvbs_diseqc_send_master_cmd function in drivers/media/usb/ttusb-dec/ttusbdecfe.c in the Linux kernel before 3.17.4 allows local users to cause a denial of service (system crash) or possibly gain privileges via a large message length in an ioctl call (CVE-2014-8884). The do_double_fault function in arch/x86/kernel/traps.c in the Linux kernel through 3.17.4 does not properly handle faults associated with the Stack Segment (SS) segment register, which allows local users to cause a denial of service (panic) via a modify_ldt system call, as demonstrated by sigreturn_32 in the linux-clock-tests test suite (CVE-2014-9090). arch/x86/kernel/entry_64.S in the Linux kernel before 3.17.5 does not properly handle faults associated with the Stack Segment (SS) segment register, which allows local users to gain privileges by triggering an IRET instruction that leads to access to a GS Base address from the wrong space (CVE-2014-9322). The __switch_to function in arch/x86/kernel/process_64.c in the Linux kernel through 3.18.1 does not ensure that Thread Local Storage (TLS) descriptors are loaded before proceeding with other steps, which makes it easier for local users to bypass the ASLR protection mechanism via a crafted application that reads a TLS base address (CVE-2014-9419). The rock_continue function in fs/isofs/rock.c in the Linux kernel through 3.18.1 does not restrict the number of Rock Ridge continuation entries, which allows local users to cause a denial of service (infinite loop, and system crash or hang) via a crafted iso9660 image (CVE-2014-9420). Race condition in the key_gc_unused_keys function in security/keys/gc.c in the Linux kernel through 3.18.2 allows local users to cause a denial of service (memory corruption or panic) or possibly have unspecified other impact via keyctl commands that trigger access to a key structure member during garbage collection of a key (CVE-2014-9529). The parse_rock_ridge_inode_internal function in fs/isofs/rock.c in the Linux kernel before 3.18.2 does not validate a length value in the Extensions Reference (ER) System Use Field, which allows local users to obtain sensitive information from kernel memory via a crafted iso9660 image (CVE-2014-9584). The vdso_addr function in arch/x86/vdso/vma.c in the Linux kernel through 3.18.2 does not properly choose memory locations for the vDSO area, which makes it easier for local users to bypass the ASLR protection mechanism by guessing a location at the end of a PMD (CVE-2014-9585). The updated packages provides a solution for these security issues.

(bnc#896392). (CVE-2014-3186) - The kvm_iommu_map_pages function in virt/kvm/iommu.c in the Linux kernel through 3.16.1 miscalculated the number of pages during the handling of a mapping failure, which allowed guest OS users to (1) cause a denial of service (host OS memory corruption) or possibly have unspecified other impact by triggering a large gfn value or (2) cause a denial of service (host OS memory consumption) by triggering a small gfn value that leads to permanently pinned pages. (bnc#892782). (CVE-2014-3601) - The WRMSR processing functionality in the KVM subsystem in the Linux kernel through 3.17.2 did not properly handle the writing of a non-canonical address to a model-specific register, which allowed guest OS users to cause a denial of service (host OS crash) by leveraging guest OS privileges, related to the wrmsr_interception function in arch/x86/kvm/svm.c and the handle_wrmsr function in arch/x86/kvm/vmx.c.

    title SuSE 11.3 Security Update : Linux kernel (SAT Patch Number 10103)
  • NASL family Oracle Linux Local Security Checks
    NASL id ORACLELINUX_ELSA-2015-0864.NASL
    description From Red Hat Security Advisory 2015:0864 : Updated kernel packages that fix multiple security issues and several bugs are now available for Red Hat Enterprise Linux 6. Red Hat Product Security has rated this update as having Important security impact. Common Vulnerability Scoring System (CVSS) base scores, which give detailed severity ratings, are available for each vulnerability from the CVE links in the References section. The kernel packages contain the Linux kernel, the core of any Linux operating system. * A flaw was found in the way seunshare, a utility for running executables under a different security context, used the capng_lock functionality of the libcap-ng library. The subsequent invocation of suid root binaries that relied on the fact that the setuid() system call, among others, also sets the saved set-user-ID when dropping the binaries' process privileges, could allow a local, unprivileged user to potentially escalate their privileges on the system. Note: the fix for this issue is the kernel part of the overall fix, and introduces the PR_SET_NO_NEW_PRIVS functionality and the related SELinux exec transitions support. (CVE-2014-3215, Important) * A use-after-free flaw was found in the way the Linux kernel's SCTP implementation handled authentication key reference counting during INIT collisions. A remote attacker could use this flaw to crash the system or, potentially, escalate their privileges on the system. (CVE-2015-1421, Important) * It was found that the Linux kernel's KVM implementation did not ensure that the host CR4 control register value remained unchanged across VM entries on the same virtual CPU. A local, unprivileged user could use this flaw to cause a denial of service on the system. (CVE-2014-3690, Moderate) * An out-of-bounds memory access flaw was found in the syscall tracing functionality of the Linux kernel's perf subsystem. A local, unprivileged user could use this flaw to crash the system. (CVE-2014-7825, Moderate) * An out-of-bounds memory access flaw was found in the syscall tracing functionality of the Linux kernel's ftrace subsystem. On a system with ftrace syscall tracing enabled, a local, unprivileged user could use this flaw to crash the system, or escalate their privileges. (CVE-2014-7826, Moderate) * It was found that the Linux kernel memory resource controller's (memcg) handling of OOM (out of memory) conditions could lead to deadlocks.

    title Oracle Linux 6 : kernel (ELSA-2015-0864)
  • NASL family Red Hat Local Security Checks
    NASL id REDHAT-RHSA-2015-0864.NASL
    description Updated kernel packages that fix multiple security issues and several bugs are now available for Red Hat Enterprise Linux 6. Red Hat Product Security has rated this update as having Important security impact. Common Vulnerability Scoring System (CVSS) base scores, which give detailed severity ratings, are available for each vulnerability from the CVE links in the References section. The kernel packages contain the Linux kernel, the core of any Linux operating system. * A flaw was found in the way seunshare, a utility for running executables under a different security context, used the capng_lock functionality of the libcap-ng library. The subsequent invocation of suid root binaries that relied on the fact that the setuid() system call, among others, also sets the saved set-user-ID when dropping the binaries' process privileges, could allow a local, unprivileged user to potentially escalate their privileges on the system. Note: the fix for this issue is the kernel part of the overall fix, and introduces the PR_SET_NO_NEW_PRIVS functionality and the related SELinux exec transitions support. (CVE-2014-3215, Important) * A use-after-free flaw was found in the way the Linux kernel's SCTP implementation handled authentication key reference counting during INIT collisions. A remote attacker could use this flaw to crash the system or, potentially, escalate their privileges on the system. (CVE-2015-1421, Important) * It was found that the Linux kernel's KVM implementation did not ensure that the host CR4 control register value remained unchanged across VM entries on the same virtual CPU. A local, unprivileged user could use this flaw to cause a denial of service on the system. (CVE-2014-3690, Moderate) * An out-of-bounds memory access flaw was found in the syscall tracing functionality of the Linux kernel's perf subsystem. A local, unprivileged user could use this flaw to crash the system. (CVE-2014-7825, Moderate) * An out-of-bounds memory access flaw was found in the syscall tracing functionality of the Linux kernel's ftrace subsystem. On a system with ftrace syscall tracing enabled, a local, unprivileged user could use this flaw to crash the system, or escalate their privileges. (CVE-2014-7826, Moderate) * It was found that the Linux kernel memory resource controller's (memcg) handling of OOM (out of memory) conditions could lead to deadlocks.

    description Updated kernel packages that fix multiple security issues and several bugs are now available for Red Hat Enterprise Linux 6.5 Extended Update Support. Red Hat Product Security has rated this update as having Important security impact. Common Vulnerability Scoring System (CVSS) base scores, which give detailed severity ratings, are available for each vulnerability from the CVE links in the References section. The kernel packages contain the Linux kernel, the core of any Linux operating system. * It was found that the Linux kernel's Infiniband subsystem did not properly sanitize input parameters while registering memory regions from user space via the (u)verbs API. A local user with access to a /dev/infiniband/uverbsX device could use this flaw to crash the system or, potentially, escalate their privileges on the system. (CVE-2014-8159, Important) * A use-after-free flaw was found in the way the Linux kernel's SCTP implementation handled authentication key reference counting during INIT collisions. A remote attacker could use this flaw to crash the system or, potentially, escalate their privileges on the system. (CVE-2015-1421, Important) * An integer overflow flaw was found in the way the Linux kernel's Frame Buffer device implementation mapped kernel memory to user space via the mmap syscall. A local user able to access a frame buffer device file (/dev/fb*) could possibly use this flaw to escalate their privileges on the system. (CVE-2013-2596, Important) * It was found that the Linux kernel's KVM implementation did not ensure that the host CR4 control register value remained unchanged across VM entries on the same virtual CPU. A local, unprivileged user could use this flaw to cause a denial of service on the system. (CVE-2014-3690, Moderate) * It was found that the parse_rock_ridge_inode_internal() function of the Linux kernel's ISOFS implementation did not correctly check relocated directories when processing Rock Ridge child link (CL) tags. An attacker with physical access to the system could use a specially crafted ISO image to crash the system or, potentially, escalate their privileges on the system. (CVE-2014-5471, CVE-2014-5472, Low) * A stack-based buffer overflow flaw was found in the TechnoTrend/Hauppauge DEC USB device driver. A local user with write access to the corresponding device could use this flaw to crash the kernel or, potentially, elevate their privileges on the system. (CVE-2014-8884, Low) Red Hat would like to thank Mellanox for reporting CVE-2014-8159, and Andy Lutomirski for reporting CVE-2014-3690. The CVE-2015-1421 issue was discovered by Sun Baoliang of Red Hat. This update also fixes the following bugs : * Previously, a NULL pointer check that is needed to prevent an oops in the nfs_async_inode_return_delegation() function was removed. As a consequence, a NFS4 client could terminate unexpectedly. The missing NULL pointer check has been added back, and NFS4 client no longer crashes in this situation. (BZ#1187638) * Due to unbalanced multicast join and leave processing, the attempt to leave a multicast group that had not previously completed a join became unresponsive. This update resolves multiple locking issues in the IPoIB multicast code that allowed multicast groups to be left before the joining was entirely completed. Now, multicast join and leave failures or lockups no longer occur in the described situation. (BZ#1187663) * A failure to leave a multicast group which had previously been joined prevented the attempt to unregister from the 'sa' service. Multiple locking issues in the IPoIB multicast join and leave processing have been fixed so that leaving a group that has completed its join process is successful. As a result, attempts to unregister from the 'sa' service no longer lock up due to leaked resources. (BZ#1187665) * Due to a regression, when large reads which partially extended beyond the end of the underlying device were done, the raw driver returned the EIO error code instead of returning a short read covering the valid part of the device. The underlying source code has been patched, and the raw driver now returns a short read for the remainder of the device. (BZ#1195746) All kernel users are advised to upgrade to these updated packages, which contain backported patches to correct these issues. The system must be rebooted for this update to take effect.

  • NASL family CentOS Local Security Checks
    NASL id CENTOS_RHSA-2015-0864.NASL
    description Updated kernel packages that fix multiple security issues and several bugs are now available for Red Hat Enterprise Linux 6. Red Hat Product Security has rated this update as having Important security impact. Common Vulnerability Scoring System (CVSS) base scores, which give detailed severity ratings, are available for each vulnerability from the CVE links in the References section. The kernel packages contain the Linux kernel, the core of any Linux operating system. * A flaw was found in the way seunshare, a utility for running executables under a different security context, used the capng_lock functionality of the libcap-ng library. The subsequent invocation of suid root binaries that relied on the fact that the setuid() system call, among others, also sets the saved set-user-ID when dropping the binaries' process privileges, could allow a local, unprivileged user to potentially escalate their privileges on the system. Note: the fix for this issue is the kernel part of the overall fix, and introduces the PR_SET_NO_NEW_PRIVS functionality and the related SELinux exec transitions support. (CVE-2014-3215, Important) * A use-after-free flaw was found in the way the Linux kernel's SCTP implementation handled authentication key reference counting during INIT collisions. A remote attacker could use this flaw to crash the system or, potentially, escalate their privileges on the system. (CVE-2015-1421, Important) * It was found that the Linux kernel's KVM implementation did not ensure that the host CR4 control register value remained unchanged across VM entries on the same virtual CPU. A local, unprivileged user could use this flaw to cause a denial of service on the system. (CVE-2014-3690, Moderate) * An out-of-bounds memory access flaw was found in the syscall tracing functionality of the Linux kernel's perf subsystem. A local, unprivileged user could use this flaw to crash the system. (CVE-2014-7825, Moderate) * An out-of-bounds memory access flaw was found in the syscall tracing functionality of the Linux kernel's ftrace subsystem. On a system with ftrace syscall tracing enabled, a local, unprivileged user could use this flaw to crash the system, or escalate their privileges. (CVE-2014-7826, Moderate) * It was found that the Linux kernel memory resource controller's (memcg) handling of OOM (out of memory) conditions could lead to deadlocks. An attacker able to continuously spawn new processes within a single memory-constrained cgroup during an OOM event could use this flaw to lock up the system. (CVE-2014-8171, Moderate) * A race condition flaw was found in the way the Linux kernel keys management subsystem performed key garbage collection. A local attacker could attempt accessing a key while it was being garbage collected, which would cause the system to crash. (CVE-2014-9529, Moderate) * A stack-based buffer overflow flaw was found in the TechnoTrend/Hauppauge DEC USB device driver. A local user with write access to the corresponding device could use this flaw to crash the kernel or, potentially, elevate their privileges on the system. (CVE-2014-8884, Low) * An information leak flaw was found in the way the Linux kernel's ISO9660 file system implementation accessed data on an ISO9660 image with RockRidge Extension Reference (ER) records. An attacker with physical access to the system could use this flaw to disclose up to 255 bytes of kernel memory. (CVE-2014-9584, Low) Red Hat would like to thank Andy Lutomirski for reporting CVE-2014-3215 and CVE-2014-3690, Robert Swiecki for reporting CVE-2014-7825 and CVE-2014-7826, and Carl Henrik Lunde for reporting CVE-2014-9584. The CVE-2015-1421 issue was discovered by Sun Baoliang of Red Hat. This update also fixes several bugs. Documentation for these changes is available from the Technical Notes document linked to in the References section. All kernel users are advised to upgrade to these updated packages, which contain backported patches to correct these issues. The system must be rebooted for this update to take effect.

CVE-2014-5206: The do_remount function in fs/namespace.c in the Linux kernel did not maintain the MNT_LOCK_READONLY bit across a remount of a bind mount, which allowed local users to bypass an intended read-only restriction and defeat certain sandbox protection mechanisms via a 'mount -o remount' command within a user namespace. CVE-2014-5207: fs/namespace.c in the Linux kernel did not properly restrict clearing MNT_NODEV, MNT_NOSUID, and MNT_NOEXEC and changing MNT_ATIME_MASK during a remount of a bind mount, which allowed local users to gain privileges, interfere with backups and auditing on systems that had atime enabled, or cause a denial of service (excessive filesystem updating) on systems that had atime disabled via a 'mount -o remount' command within a user namespace. CVE-2014-1739: The media_device_enum_entities function in drivers/media/media-device.c in the Linux kernel did not initialize a certain data structure, which allowed local users to obtain sensitive information from kernel memory by leveraging /dev/media0 read access for a MEDIA_IOC_ENUM_ENTITIES ioctl call. CVE-2014-4943: The PPPoL2TP feature in net/l2tp/l2tp_ppp.c in the Linux kernel allowed local users to gain privileges by leveraging data-structure differences between an l2tp socket and an inet socket. CVE-2014-4508: arch/x86/kernel/entry_32.S in the Linux kernel on 32-bit x86 platforms, when syscall auditing is enabled and the sep CPU feature flag is set, allowed local users to cause a denial of service (OOPS and system crash) via an invalid syscall number, as demonstrated by number 1000. CVE-2014-5077: The sctp_assoc_update function in net/sctp/associola.c in the Linux kernel, when SCTP authentication is enabled, allowed remote attackers to cause a denial of service (NULL pointer dereference and OOPS) by starting to establish an association between two endpoints immediately after an exchange of INIT and INIT ACK chunks to establish an earlier association between these endpoints in the opposite direction. CVE-2014-4171: mm/shmem.c in the Linux kernel did not properly implement the interaction between range notification and hole punching, which allowed local users to cause a denial of service (i_mutex hold) by using the mmap system call to access a hole, as demonstrated by interfering with intended shmem activity by blocking completion of (1) an MADV_REMOVE madvise call or (2) an FALLOC_FL_PUNCH_HOLE fallocate call. Also the following bugs were fixed : - KEYS: Fix stale key registration at error path (bnc#908163). - parport: parport_pc, do not remove parent devices early (bnc#856659). - xfs: fix directory hash ordering bug. - xfs: mark all internal workqueues as freezable (bnc#899785). - [media] uvc: Fix destruction order in uvc_delete() (bnc#897736). - cfq-iosched: Fix wrong children_weight calculation (bnc#893429). - target/rd: Refactor rd_build_device_space + rd_release_device_space (bnc#882639). - Btrfs: Fix memory corruption by ulist_add_merge() on 32bit arch (bnc#887046). - usb: pci-quirks: Prevent Sony VAIO t-series from switching usb ports (bnc#864375). - xhci: Switch only Intel Lynx Point-LP ports to EHCI on shutdown (bnc#864375). - xhci: Switch Intel Lynx Point ports to EHCI on shutdown (bnc#864375). - ALSA: hda - Fix broken PM due to incomplete i915 initialization (bnc#890114). - netbk: Don't destroy the netdev until the vif is shut down (bnc#881008). - swiotlb: don't assume PA 0 is invalid (bnc#865882). - PM / sleep: Fix request_firmware() error at resume (bnc#873790). - usbcore: don't log on consecutive debounce failures of the same port (bnc#818966).

    description An information leak in the Linux kernel was discovered that could leak the high 16 bits of the kernel stack address on 32-bit Kernel Virtual Machine (KVM) paravirt guests. A user in the guest OS could exploit this leak to obtain information that could potentially be used to aid in attacking the kernel. (CVE-2014-8134) A flaw in the handling of malformed ASCONF chunks by SCTP (Stream Control Transmission Protocol) implementation in the Linux kernel was discovered. A remote attacker could exploit this flaw to cause a denial of service (system crash). (CVE-2014-3673) A flaw in the handling of duplicate ASCONF chunks by SCTP (Stream Control Transmission Protocol) implementation in the Linux kernel was discovered. A remote attacker could exploit this flaw to cause a denial of service (panic). (CVE-2014-3687) It was discovered that excessive queuing by SCTP (Stream Control Transmission Protocol) implementation in the Linux kernel can cause memory pressure. A remote attacker could exploit this flaw to cause a denial of service. (CVE-2014-3688) A NULL pointer dereference flaw was discovered in the the Linux kernel's SCTP implementation when ASCONF is used. A remote attacker could exploit this flaw to cause a denial of service (system crash) via a malformed INIT chunk. (CVE-2014-7841) Jouni Malinen reported a flaw in the handling of fragmentation in the mac8Linux subsystem of the kernel. A remote attacker could exploit this flaw to obtain potential sensitive cleartext information by reading packets. (CVE-2014-8709) A stack buffer overflow was discovered in the ioctl command handling for the Technotrend/Hauppauge USB DEC devices driver. A local user could exploit this flaw to cause a denial of service (system crash) or possibly gain privileges. (CVE-2014-8884) Andy Lutomirski discovered that the Linux kernel does not properly handle faults associated with the Stack Segment (SS) register on the x86 architecture. A local attacker could exploit this flaw to cause a denial of service (panic). (CVE-2014-9090). Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
