Ubuntu 13.10 : linux vulnerabilities (USN-2289-1)

high Nessus Plugin ID 76568

Language:

Synopsis

The remote Ubuntu host is missing one or more security-related patches.

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)

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)

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.

Solution

Update the affected linux-image-3.11-generic and / or linux-image-3.11-generic-lpae packages.
