Ubuntu 7.04 : linux-source-2.6.20 vulnerabilities (USN-470-1)

medium Nessus Plugin ID 28071

Synopsis

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

Description

USN-464-1 fixed several vulnerabilities in the Linux kernel. Some additional code changes were accidentally included in the Feisty update which caused trouble for some people who were not using UUID-based filesystem mounts. These changes have been reverted. We apologize for the inconvenience. For more information see:
https://launchpad.net/bugs/117314 https://wiki.ubuntu.com/UsingUUID

Ilja van Sprundel discovered that Bluetooth setsockopt calls could leak kernel memory contents via an uninitialized stack buffer. A local attacker could exploit this flaw to view sensitive kernel information.
(CVE-2007-1353)

The GEODE-AES driver did not correctly initialize its encryption key.
Any data encrypted using this type of device would be easily compromised. (CVE-2007-2451)

The random number generator was hashing a subset of the available entropy, leading to slightly less random numbers. Additionally, systems without an entropy source would be seeded with the same inputs at boot time, leading to a repeatable series of random numbers.
(CVE-2007-2453).

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 packages.
