CVE-2009-3525 Information

Description

The pyGrub boot loader in Xen 3.0.3 3.3.0 and Xen-3.3.1 does not support the password option in grub.conf for para-virtualized guests which allows attackers with access to the para-virtualized guest console to boot the guest or modify the guest’s kernel boot parameters without providing the expected password.
