Description


Some security issues have been reported in the Linux Kernel, which can be exploited by malicious, local users to cause a DoS (Denial of Service).

1) A security issue is caused due to the KVM implementation allowing a guest machine direct access to host port 80h and can be exploited to hang the host system.

NOTE: The security issue only affects certain AMD platforms.

2) A security issue is caused due to a locking error within the implementation of the "splice()" system call, which can be exploited to e.g. deadlock other applications.

The security issues are reported in versions prior to 2.6.29.4.


Solution:
Update to version 2.6.29.4.

Provided and/or discovered by:
1) Piotr Jaroszynski
2) Miklos Szeredi
