Description

UNIX-V6 contains a flaw that may allow a local attacker to gain increased privileges. The flaw occurs when an attacker intentionally exhausts all file descriptors before executing the 'su' program. In such a case, 'su' would invoke a super-user shell instead of failing to execute.

Classification

Location: Local Access Required
Attack Type: Input Manipulation
Impact: Loss of Integrity
Exploit: Exploit Public
