Debian DSA-257-1 : sendmail - remote exploit

critical Nessus Plugin ID 15094


The remote Debian host is missing a security-related update.


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).
