| Description: | Description:
The remote host is missing updates announced in
advisory CLA-2003:614.
Sendmail[1] is a widely used Mail Transfer Agent (MTA).
Michal Zalewski reported[6] a remote vulnerability[5] in sendmail
versions 8.12.8 and below. The vulnerability lies in the address
parser which performs insufficient bounds checking in certain
conditions due to a char to int conversion.
It is believed to be possible for remote attackers to cause a Denial
of Service condition and to even execute arbitrary commands with the
same permissions under which the sendmail daemon runs, which is
root.
The sendmail authors have released a new version[2], 8.12.9, which
fixes this vulnerability. They have also made available patches[3]
for older versions, which the packages provided via this announcement
contain.
Starting with Conectiva Linux 7.0, sendmail is no longer the default
mail server and has been replaced with Postfix. But sendmail is still
shipped in all Conectiva Linux versions.
Solution:
The apt tool can be used to perform RPM package upgrades
by running 'apt-get update' followed by 'apt-get upgrade'
