TITLE:
Linux Kernel KVM Port 80h Denial of Service Security Issue

SECUNIA ADVISORY ID:
SA35127

VERIFY ADVISORY:
http://secunia.com/advisories/35127/

DESCRIPTION:
A security issue has been reported in the Linux Kernel, which can be
exploited by malicious, local users to cause a DoS (Denial of
Service).

The 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.

The security issue is reported in versions prior to 2.6.30-rc6.

SOLUTION:
Fixed in 2.6.30-rc6.
