Detail

A security issue affects the following Ubuntu releases:

Ubuntu 7.04

This advisory also applies to the corresponding versions of Kubuntu, Edubuntu, and Xubuntu.

The problem can be corrected by upgrading your system to the following package versions:

Ubuntu 7.04:
linux-image-2.6.20-16-386 2.6.20-16.29
linux-image-2.6.20-16-generic 2.6.20-16.29
linux-image-2.6.20-16-hppa32 2.6.20-16.29
linux-image-2.6.20-16-hppa64 2.6.20-16.29
linux-image-2.6.20-16-itanium 2.6.20-16.29
linux-image-2.6.20-16-lowlatency 2.6.20-16.29
linux-image-2.6.20-16-mckinley 2.6.20-16.29
linux-image-2.6.20-16-powerpc 2.6.20-16.29
linux-image-2.6.20-16-powerpc-smp 2.6.20-16.29
linux-image-2.6.20-16-powerpc64-smp 2.6.20-16.29
linux-image-2.6.20-16-server 2.6.20-16.29
linux-image-2.6.20-16-server-bigiron 2.6.20-16.29
linux-image-2.6.20-16-sparc64 2.6.20-16.29
linux-image-2.6.20-16-sparc64-smp 2.6.20-16.29

After a standard system upgrade you need to reboot your computer to effect the necessary changes.

Details follow:

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://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)

Title: The setsockopt function in the L2CAP and HCI Bluetooth support in the Linux kernel before 2.4.34.3 allows context-dependent attackers to read kernel memory and obtain sensitive information via unspecified vectors involving the copy_from_user function accessing an uninitialized stack buffer.

Title: The random number feature in Linux kernel 2.6 before 2.6.20.13, and 2.6.21.x before 2.6.21.4, (1) does not properly seed pools when there is no entropy, or (2) uses an incorrect cast when extracting entropy, which might cause the random number generator to provide the same values after reboots on systems without an entropy source.
