Technical details

The chroot utility in Digital Ultrix versions 4.0 and 4.1 is improperly installed, leading to a privilege escalation vulnerability. While the specific mechanism (such as setuid bits or directory permissions) is not detailed in the legacy advisory, the flaw allows a local attacker to break out of restricted environments or manipulate the system to gain root access. This is a local attack requiring no special authentication beyond initial system access. The vulnerability was originally identified in 1991 and is addressed in subsequent vendor patches or version upgrades.
