CONECTIVA LINUX SECURITY ANNOUNCEMENT 
- --------------------------------------------------------------------------

PACKAGE   : sendmail
SUMMARY   : Local vulnerability
DATE      : 2002-10-16 15:49:00
ID        : CLA-2002:532
RELEVANT
RELEASES  : 6.0, 7.0, 8

DESCRIPTION
 Sendmail is a widely used Mail Transfer Agent (MTA). "smrsh" is an
 application intended as a replacement for the sh shell for use with
 Sendmail. It imposes some restrictions to what programs can be
 executed when parsing ~/.forward and system wide mail aliases.
 
 Zen-parse and Pedram Amini found two ways[1] to exploit smrsh in
 order to make it execute any program on the system. The first one is
 by inserting specially formatted commands in the .forward file
 located in the user's home directory. The second one is by directly
 calling smrsh with special parameters.
 
 By exploiting this vulnerability, users who have no shell account or
 are not allowed to execute some programs can use smrsh to bypass such
 restrictions.
 
 The Common Vulnerabilities and Exposures project (cve.mitre.org) has
 assigned the name CAN-2002-1165 to this issue[2].


SOLUTION
 All sendmail users should upgrade.
