Technical details

A buffer overflow vulnerability exists within the 'passwd' executable in HP-UX. The flaw is triggered by providing an overly long or malformed string to a specific command-line option, which fails to perform adequate bounds checking. Because the 'passwd' utility typically runs with elevated (SetUID root) privileges to modify system authentication files, a successful exploit allows a local, unprivileged attacker to execute arbitrary code with root authority. This is a classic local privilege escalation (LPE) vulnerability. HP released advisory HPSBUX9701-045 to address this issue.
