Ubuntu 10.04 LTS / 10.10 / 11.04 : qemu-kvm vulnerability (USN-1177-1)

low Nessus Plugin ID 55717

Language:

Synopsis

The remote Ubuntu host is missing one or more security-related patches.

Description

Andrew Griffiths discovered that QEMU did not correctly drop privileges when using the 'runas' argument. Under certain circumstances a local attacker could exploit this to escalate privileges.

Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Solution

Update the affected qemu-kvm, qemu-kvm-extras and / or qemu-kvm-extras-static packages.
