Linux VServer Project CHRoot Breakout Vulnerability

VServer is reported prone to a breakout vulnerability that allows a malicious user to escape from the context of the chrooted root directory of the virtual server. This issue is due to the VServer application failing to secure itself against a "chroot-again" style vulnerability. Successful exploitation of this issue may allow an attacker to gain access to the filesystem outside of the chrooted root directory.
