DESCRIPTION:
Red Hat has issued an update for the kernel. This fixes two
weaknesses and multiple vulnerabilities, which can be exploited by
malicious, local users to disclose potentially sensitive information,
conduct session hijacking attacks, and cause a DoS (Denial of
Service), by malicious, local users in a guest virtual machine to
cause a DoS, and by malicious people to cause a DoS.

overflow by inserting a malicious USB device.
