Ubuntu 10.04 LTS : linux-ec2 vulnerabilities (USN-1161-1)

high Nessus Plugin ID 55590

Language:

Synopsis

The remote Ubuntu host is missing a security-related patch.

Description

Vasiliy Kulikov discovered that kvm did not correctly clear memory. A local attacker could exploit this to read portions of the kernel stack, leading to a loss of privacy. (CVE-2010-3881)

Timo Warns discovered that the LDM disk partition handling code did not correctly handle certain values. By inserting a specially crafted disk device, a local attacker could exploit this to gain root privileges. (CVE-2011-1017)

Neil Horman discovered that NFSv4 did not correctly handle certain orders of operation with ACL data. A remote attacker with access to an NFSv4 mount could exploit this to crash the system, leading to a denial of service. (CVE-2011-1090)

Timo Warns discovered that OSF partition parsing routines did not correctly clear memory. A local attacker with physical access could plug in a specially crafted block device to read kernel memory, leading to a loss of privacy. (CVE-2011-1163)

Dan Rosenberg discovered that MPT devices did not correctly validate certain values in ioctl calls. If these drivers were loaded, a local attacker could exploit this to read arbitrary kernel memory, leading to a loss of privacy. (CVE-2011-1494, CVE-2011-1495)

Tavis Ormandy discovered that the pidmap function did not correctly handle large requests. A local attacker could exploit this to crash the system, leading to a denial of service. (CVE-2011-1593)

Oliver Hartkopp and Dave Jones discovered that the CAN network driver did not correctly validate certain socket structures. If this driver was loaded, a local attacker could crash the system, leading to a denial of service. (CVE-2011-1598, CVE-2011-1748)

Vasiliy Kulikov discovered that the AGP driver did not check certain ioctl values. A local attacker with access to the video subsystem could exploit this to crash the system, leading to a denial of service, or possibly gain root privileges. (CVE-2011-1745, CVE-2011-2022)

Vasiliy Kulikov discovered that the AGP driver did not check the size of certain memory allocations. A local attacker with access to the video subsystem could exploit this to run the system out of memory, leading to a denial of service. (CVE-2011-1746)

Dan Rosenberg reported an error in the old ABI compatibility layer of ARM kernels. A local attacker could exploit this flaw to cause a denial of service or gain root privileges. (CVE-2011-1759)

Dan Rosenberg discovered that the DCCP stack did not correctly handle certain packet structures. A remote attacker could exploit this to crash the system, leading to a denial of service. (CVE-2011-1770)

Timo Warns discovered that the EFI GUID partition table was not correctly parsed. A physically local attacker that could insert mountable devices could exploit this to crash the system or possibly gain root privileges. (CVE-2011-1776)

Yogesh Sharma discovered that CIFS did not correctly handle UNCs that had no prefixpaths. A local attacker with access to a CIFS partition could exploit this to crash the system, leading to a denial of service. (CVE-2011-3363).

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.

Solution

Update the affected linux-image-2.6-ec2 package.
