Title: HP-UX SWVerify Buffer Overflow Vulnerability
Severity: HIGH
Description:
HP-UX is the UNIX Operating System variant distributed by Hewlett-Packard, available for use on systems of size varying from workgroup servers to enterprise systems.
A problem has been discovered in HP-UX that could allow a local user to gain elevated privileges. The vulnerability could result in complete system compromise.
The problem is due to a buffer overflow in swverify. By supplying a string of 6039 bytes, a buffer overflow occurs, allowing the user to overwrite stack variables, including the return address.
As the swverify program is setuid root, this makes it possible for the local user to gain an elevation of privileges to root.
Affected Products:
- HP HP-UX 11.0.0
