Disclosure Date


A local overflow exists in SCO UnixWare. UnixWare fails to check the boundary of arguments supplied to the "Xsco" command, resulting in a buffer overflow. By passing an overly long argument (argv[1]) to Xsco, an local attacker can cause a buffer overflow and gain superuser privileges, resulting in a loss of integrity.


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


Currently, there are no known workarounds or upgrades to correct this issue. However, SCO has released a patch to address this vulnerability.
