Description

Sasha Levin reported a flaw in the Linux kernel’s point-to-point protocol (PPP) when used with the Layer Two Tunneling Protocol (L2TP). A local user could exploit this flaw to gain administrative privileges. (CVE-2014-4943)

Michael S. Tsirkin discovered an information leak in the Linux kernel’s segmentation of skbs when using the zerocopy feature of vhost-net. A local attacker could exploit this flaw to gain potentially sensitive information from kernel memory. (CVE-2014-0131)

Salva Peiró discovered an information leak in the Linux kernel’s media- device driver. A local attacker could exploit this flaw to obtain sensitive information from kernel memory. (CVE-2014-1739)

A bounds check error was discovered in the socket filter subsystem of the Linux kernel. A local user could exploit this flaw to cause a denial of service (system crash) via crafted BPF instructions. (CVE-2014-3144)

A remainder calculation error was discovered in the socket filter subsystem of the Linux kernel. A local user could exploit this flaw to cause a denial of service (system crash) via crafted BPF instructions. (CVE-2014-3145)

An flaw was discovered in the Linux kernel’s audit subsystem when auditing certain syscalls. A local attacker could exploit this flaw to obtain potentially sensitive single-bit values from kernel memory or cause a denial of service (OOPS). (CVE-2014-3917)

A flaw was discovered in the Linux kernel’s implementation of user namespaces with respect to inode permissions. A local user could exploit this flaw by creating a user namespace to gain administrative privileges. (CVE-2014-4014)

Don Bailey discovered a flaw in the LZO decompress algorithm used by the Linux kernel. An attacker could exploit this flaw to cause a denial of service (memory corruption or OOPS). (CVE-2014-4608)
