An attacker could use this to craft input that could cause a denial of service (application crash) or possibly execute arbitrary code. (CVE-2014-8485) Hanno Böck discovered that the bfdXXiswapaouthdrin function in libbfd in GNU binutils allowed out-of-bounds writes. An attacker could use this to craft input that could cause a denial of service (application crash) or possibly execute arbitrary code. (CVE-2014-8501) Hanno Böck discovered a heap-based buffer overflow in the peprintedata function in libbfd in GNU binutils. An attacker could use this to craft input that could cause a denial of service (application crash) or possibly execute arbitrary code. (CVE-2014-8502) Alexander Cherepanov discovered multiple directory traversal vulnerabilities in GNU binutils. An attacker could use this to craft input that could delete arbitrary files. (CVE-2014-8737) Alexander Cherepanov discovered the bfdslurpextendednametable function in libbfd in GNU binutils allowed invalid writes when handling extended name tables in an archive. An attacker could use this to craft input that could cause a denial of service (application crash) or possibly execute arbitrary code. (CVE-2014-8738) Hanno Böck discovered a stack-based buffer overflow in the ihexscan function in libbfd in GNU binutils. An attacker could use this to craft input that could cause a denial of service (application crash). (CVE-2014-8503) Michal Zalewski discovered a stack-based buffer overflow in the srecscan function in libbfd in GNU binutils. An attacker could use this to to craft input that could cause a denial of service (application crash); the GNU C library's Fortify Source printf protection should prevent the possibility of executing arbitrary code. (CVE-2014-8504) Michal Zalewski discovered that the srecscan function in libbfd in GNU binutils allowed out-of-bounds reads. An attacker could use this to craft input to cause a denial of service. This issue only affected Ubuntu 14.04 LTS, Ubuntu 12.04 LTS, and Ubuntu 10.04 LTS. (CVE-2014-8484) Sang Kil Cha discovered multiple integer overflows in the objallocalloc function and objallocalloc macro in binutils. This could allow an attacker to cause a denial of service (application crash). This issue only affected Ubuntu 12.04 LTS and Ubuntu 10.04 LTS. (CVE-2012-3509) Alexander Cherepanov and Hanno Böck discovered multiple additional out-of-bounds reads and writes in GNU binutils. An attacker could use these to craft input that could cause a denial of service (application crash) or possibly execute arbitrary code. A few of these issues may be limited in exposure to a denial of service (application abort) by the GNU C library's Fortify Source printf protection. The strings(1) utility in GNU binutils used libbfd by default when examining executable object files; unfortunately, libbfd was not originally developed with the expectation of hostile input. As a defensive measure, the behavior of strings has been changed to default to 'strings --all' behavior, which does not use libbfd; use the new argument to strings, '--data', to recreate the old behavior.

Andy Lutomirski discovered that the Linux kernel does not properly handle faults associated with the Stack Segment (SS) register in the x86 architecture. A local attacker could exploit this flaw to gain administrative privileges. (CVE-2014-9322) 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) Rabin Vincent, Robert Swiecki, Russell King discovered that the ftrace subsystem of the Linux kernel does not properly handle private syscall numbers. A local user could exploit this flaw to cause a denial of service (OOPS). (CVE-2014-7826) 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) Rabin Vincent, Robert Swiecki, Russell Kinglaw discovered a flaw in how the perf subsystem of the Linux kernel handles private systecall numbers.

(CVE-2014-7825) Andy Lutomirski discovered a flaw in how the Linux kernel handles pivotroot when used with a chroot directory. A local user could exploit this flaw to cause a denial of service (mount-tree loop). (CVE-2014-7970) Dmitry Monakhov discovered a race condition in the ext4filewriteiter function of the Linux kernel's ext4 filesystem. A local user could exploit this flaw to cause a denial of service (file unavailability). (CVE-2014-8086) The KVM (kernel virtual machine) subsystem of the Linux kernel miscalculates the number of memory pages during the handling of a mapping failure. A guest OS user could exploit this to cause a denial of service (host OS page unpinning) or possibly have unspecified other impact by leveraging guest OS privileges.

A flaw was discovered in how the Linux kernel's KVM (Kernel Virtual Machine) subsystem handles the CR4 control register at VM entry on Intel processors.

A local user could exploit this flaw to cause a denial of service (loss of writability). (CVE-2014-7975)

Nadav Amit reported that the KVM (Kernel Virtual Machine) mishandles noncanonical addresses when emulating instructions that change the rip (Instruction Pointer).
