Title:	Ubuntu: Security Advisory (USN-1389-1)
Summary:	The remote host is missing an update for the 'linux' package(s) announced via the USN-1389-1 advisory.
Description:	Summary: The remote host is missing an update for the 'linux' package(s) announced via the USN-1389-1 advisory. Vulnerability Insight: Paolo Bonzini discovered a flaw in Linux's handling of the SG_IO ioctl command. A local user, or user in a VM could exploit this flaw to bypass restrictions and gain read/write access to all data on the affected block device. (CVE-2011-4127) A flaw was found in KVM's Programmable Interval Timer (PIT). When a virtual interrupt control is not available a local user could use this to cause a denial of service by starting a timer. (CVE-2011-4622) A flaw was discovered in the XFS filesystem. If a local user mounts a specially crafted XFS image it could potential execute arbitrary code on the system. (CVE-2012-0038) A flaw was found in the Linux kernel's ext4 file system when mounting a corrupt filesystem. A user-assisted remote attacker could exploit this flaw to cause a denial of service. (CVE-2012-2100) Affected Software/OS: 'linux' package(s) on Ubuntu 10.04. Solution: Please install the updated package(s). CVSS Score: 7.1 CVSS Vector: AV:N/AC:M/Au:N/C:N/I:N/A:C
