--- Issue Specifics ---

login is a program that local and remote connection mechanisms often
invoke to facilitate logging into a Unix system.

A vulnerability has been discovered in the login program for many
System V-derived Unix implementations that allows unauthorized root
access. More details can be found in CERT advisory CA-2001-34:

Silicon Graphics has investigated the issue and finds that IRIX 3.x may
have had this issue, as mentioned in the CERT advisory. Any versions of
IRIX that are more current than IRIX 3.x, including IRIX 4.x, IRIX 5.x,
and IRIX 6.x, do NOT have this login vulnerability, and no further action
is required.
