Linux kernel vulnerabilities

Releases

• Ubuntu 7.04

Details

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:

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)
