Ubuntu 10.04 LTS : linux-lts-backport-maverick vulnerabilities (USN-1205-1)

Ubuntu Security Notice (C) 2011-2014 Canonical, Inc. / NASL script (C) 2011-2014 Tenable Network Security, Inc.


Synopsis :

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

Description :

It was discovered that the /proc filesystem did not correctly handle
permission changes when programs executed. A local attacker could hold
open files to examine details about programs running with higher
privileges, potentially increasing the chances of exploiting
additional vulnerabilities. (CVE-2011-1020)

Dan Rosenberg discovered that the X.25 Rose network stack did not
correctly handle certain fields. If a system was running with Rose
enabled, a remote attacker could send specially crafted traffic to
gain root privileges. (CVE-2011-1493)

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)

Vasiliy Kulikov discovered that taskstats listeners were not correctly
handled. A local attacker could exploit this to exhaust memory and CPU
resources, leading to a denial of service. (CVE-2011-2484)

It was discovered that Bluetooth l2cap and rfcomm did not correctly
initialize structures. A local attacker could exploit this to read
portions of the kernel stack, leading to a loss of privacy.
(CVE-2011-2492).

Solution :

Update the affected packages.

Risk factor :

High / CVSS Base Score : 7.8
