Mandriva Linux Security Update Advisory
_______________________________________________________________________

Package name: masqmail
Advisory ID: MDKSA-2005:168
Date: September 20th, 2005

Affected versions: Multi Network Firewall 2.0
______________________________________________________________________

Problem Description:

Jens Steube discovered two vulnerabilities in masqmail:

When sending failed mail messages, the address was not properly
sanitized which could allow a local attacker to execute arbitrary
commands as the mail user (CAN-2005-2662).

When opening the log file, masqmail did not relinquish privileges,
which could allow a local attacker to overwrite arbitrary files via a
symlink attack (CAN-2005-2663).

The updated packages have been patched to address these issues.
