[USN-1935-1] Linux kernel vulnerabilities

Severity High

CVEs 6

Several security issues were fixed in the kernel.

Chanam Park reported a Null pointer flaw in the Linux kernel's Ceph client.
A remote attacker could exploit this flaw to cause a denial of service
(system crash). (CVE-2013-1059)

An information leak was discovered in the Linux kernel's fanotify
interface. A local user could exploit this flaw to obtain sensitive
information from kernel memory. (CVE-2013-2148)

Jonathan Salwan discovered an information leak in the Linux kernel's cdrom
driver. A local user can exploit this leak to obtain sensitive information
from kernel memory if the CD-ROM drive is malfunctioning. (CVE-2013-2164)

Kees Cook discovered a format string vulnerability in the Linux kernel's
disk block layer. A local user with administrator privileges could exploit
this flaw to gain kernel privileges. (CVE-2013-2851)

Hannes Frederic Sowa discovered that the Linux kernel's IPv6 stack does not
correctly handle Router Advertisement (RA) message in some cases. A remote
attacker could exploit this flaw to cause a denial of service (system
crash). (CVE-2013-4125)

A vulnerability was discovered in the Linux kernel's vhost net driver. A
local user could cause a denial of service (system crash) by powering on a
virtual machine. (CVE-2013-4127)
