Releases

• Ubuntu 12.10

Packages

• linux-ti-omap4 - Linux kernel for OMAP4

Details

Brad Spengler discovered a flaw in the Linux kernel’s uname system call. An
unprivileged user could exploit this flaw to read kernel stack memory.
(CVE-2012-0957)

Rodrigo Freire discovered a flaw in the Linux kernel’s TCP illinois
congestion control algorithm. A local attacker could use this to cause a
denial of service. (CVE-2012-4565)

Mathias Krause discovered a flaw in the Linux kernel’s XFRM netlink
interface. A local user with the NET_ADMIN capability could exploit this
flaw to leak the contents of kernel memory. (CVE-2012-6536)

Mathias Krause discovered several errors in the Linux kernel’s xfrm_user
implementation. A local attacker could exploit these flaws to examine parts
of kernel memory. (CVE-2012-6537)

Mathias Krause discovered an information leak in the Linux kernel’s
xfrm_user copy_to_user_auth function. A local user could exploit this flaw
to examine parts of kernel heap memory. (CVE-2012-6538)

A flaw was discovered in the Linux kernels handling of memory ranges with
PROT_NONE when transparent hugepages are in use. An unprivileged local user
could exploit this flaw to cause a denial of service (crash the system).
(CVE-2013-0309)

Mathias Krause discovered a flaw in xfrm_user in the Linux kernel. A local
attacker with NET_ADMIN capability could potentially exploit this flaw to
escalate privileges. (CVE-2013-1826)
