Conectiva Linux Advisory: sendmail

CONECTIVA LINUX SECURITY ANNOUNCEMENT

DESCRIPTION
Sendmail[1] is a widely used Mail Transfer Agent (MTA).

Sendmail versions 8.12.8 and before (but only of the 8.12.x
branch) have a remote vulnerability[2] related to DNS maps. If such
maps are being used, invalid DNS responses will make sendmail
attempt to free incorrect memory areas, usually resulting in a
crash. It has not been determined whether this vulnerability can be
used to execute remote commands or not.

The packages supplied via this update contain a patch[3] to fix
this vulnerability.

SOLUTION
It is recommended that all sendmail users upgrade their packages.
After the upgrade, the sendmail service will automatically be
restarted if it was already running before.
