Title: SGI IRIX Mail Core Dump Vulnerability

Severity: MODERATE

Description:

IRIX is the Unix derivative operating system distributed and maintained by SGI.

A problem has been discovered in IRIX that may potentially lead to elevated privileges. The problem is in the mail program.

Under some circumstances, it may be possible for a local user to force the mail program to core dump. This problem is likely due to a buffer overflow. As the mail program is typically a setgid mail executable, this could lead to a local privilege elevation.

This problem may make it possible for a local user to gain read access to member's email, including that of root.
