Mandrake Linux Security Update Advisory
________________________________________________________
Package name: sendmail
Advisory ID: MDKSA-2002:083
Date: November 28th, 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.
