sendmail - remote exploit

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.

DSA-257-2: Updated sendmail-wide packages are available in package
version 8.9.3+3.2W-24 for Debian 2.2 (potato) and
version 8.12.3+3.5Wbeta-5.2 for Debian 3.0 (woody).
