Debian Security Advisory DSA-257-1                   security@debian.org

Package        : sendmail
Problem type   : remote exploit
Debian-specific: no

Mark Dowd of ISS X-Force found a bug in the header parsing routines
of sendmail: it could overflow a buffer overflow when encountering
addresses with very long comments. Since sendmail also parses headers 
when forwarding emails this vulnerability can hit mail-servers which do
not deliver the email as well.

This has been fixed in upstream release 8.12.8, version 8.12.3-5 of
the package for Debian GNU/Linux 3.0/woody and version 8.9.3-25 of the
package for Debian GNU/Linux 2.2/potato.

------------------------------------------------------------------------

Obtaining updates:

  By hand:
    wget URL
        will fetch the file for you.
    dpkg -i FILENAME.deb
        will install the fetched file.

  With apt:
    deb http://security.debian.org/ stable/updates main
        added to /etc/apt/sources.list will provide security updates

Additional information can be found on the Debian security webpages
at http://www.debian.org/security/
