Ubuntu 10.04 LTS : linux-lts-backport-oneiric vulnerabilities (USN-1384-1)

high Nessus Plugin ID 58265

Synopsis

The remote Ubuntu host is missing one or more security-related patches.

Description

A bug was discovered in the Linux kernel's calculation of OOM (Out of memory) scores, that would result in the wrong process being killed. A user could use this to kill the process with the highest OOM score, even if that process belongs to another user or the system.
(CVE-2011-4097)

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)

Andy Whitcroft discovered a that the Overlayfs filesystem was not doing the extended permission checks needed by cgroups and Linux Security Modules (LSMs). A local user could exploit this to by-pass security policy and access files that should not be accessible.
(CVE-2012-0055)

A flaw was found in the linux kernels IPv4 IGMP query processing. A remote attacker could exploit this to cause a denial of service.
(CVE-2012-0207)

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).

Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
