Category:	Ubuntu Local Security Checks
Title:	Ubuntu: Security Advisory (USN-1646-1)
Summary:	The remote host is missing an update for the 'linux' package(s) announced via the USN-1646-1 advisory.
Description:	Summary: The remote host is missing an update for the 'linux' package(s) announced via the USN-1646-1 advisory. Vulnerability Insight: 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) Affected Software/OS: 'linux' package(s) on Ubuntu 12.10. Solution: Please install the updated package(s). CVSS Score: 6.2 CVSS Vector: AV:L/AC:H/Au:N/C:C/I:C/A:C
