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)

Salva Peiro 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)

A flaw was discovered in the Linux kernel's handling of hugetlb entries. A local user could exploit this flaw to cause a denial service (memory corruption or system crash). (CVE-2014-3940)

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)

Don Bailey and Ludvig Strigeus discovered an integer overflow in the Linux kernel's implementation of the LZ4 decompression algorithm, when used by code not complying with API limitations. An attacker could exploit this flaw to cause a denial of service (memory corruption) or possibly other unspecified impact. (CVE-2014-4611).

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.
