MDKSA-2002:083 - Updated sendmail packages fix smrsh insecurities

by Nikola Strahija on November 29th, 2002 Affected versions: 7.2, 8.0, 8.1, 8.2, 9.0


Problem Description:

A vulnerability was discovered by zen-parse and Pedram Amini in the
sendmail MTA. They found two ways to exploit smrsh, an application
intended as a replacement for the sh shell for use with sendmail; the
first by inserting specially formatted commands in the ~/.forward file
and secondly by calling smrsh directly with special options. These
can be exploited to give users with no shell account, or those not
permitted to execute certain programs or commands, the ability to bypass
these restrictions.
