Category:	Ubuntu Local Security Checks
Title:	Ubuntu: Security Advisory (USN-1651-1)
Summary:	The remote host is missing an update for the 'linux' package(s) announced via the USN-1651-1 advisory.
Description:	Summary: The remote host is missing an update for the 'linux' package(s) announced via the USN-1651-1 advisory. Vulnerability Insight: 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 an information leak in the Linux kernel's TUN/TAP device driver. A local user could exploit this flaw to examine part of the kernel's stack memory. (CVE-2012-6547) Denys Fedoryshchenko discovered a flaw in the Linux kernel's TCP receive processing for IPv4. A remote attacker could exploit this flaw to cause a denial of service (kernel resource consumption) via a flood of SYN+FIN TCP packets. (CVE-2012-6638) A flaw was discovered in the requeuing of futexes in the Linux kernel. A local user could exploit this flaw to cause a denial of service (system crash) or possibly have other unspecified impact. (CVE-2012-6647) A flaw was found in Linux kernel's validation of CIPSO (Common IP Security Option) options set from userspace. A local user that can set a socket's CIPSO options could exploit this flaw to cause a denial of service (crash the system). (CVE-2013-0310) Mathias Krause discover an error in Linux kernel's Datagram Congestion Control Protocol (DCCP) Congestion Control Identifier (CCID) use. A local attack could exploit this flaw to cause a denial of service (crash) and potentially escalate privileges if the user can mmap page 0. (CVE-2013-1827) Affected Software/OS: 'linux' package(s) on Ubuntu 10.04. Solution: Please install the updated package(s). CVSS Score: 7.8 CVSS Vector: AV:N/AC:L/Au:N/C:N/I:N/A:C
