[slackware-security] Sendmail buffer overflow fixed (NEW)
The sendmail packages in Slackware 8.0, 8.1, and 9.0 have been patched
to fix a security problem. Note that this vulnerablity is NOT the same
one that was announced on March 3rd and requires a new fix.
All sites running sendmail should upgrade.
More information on the problem can be found here:
http://www.sendmail.org/8.12.9.html
Here are the details from the Slackware 9.0 ChangeLog:
+--------------------------+
Sat Mar 29 13:46:36 PST 2003
patches/packages/sendmail-8.12.9-i386-1.tgz: Upgraded to sendmail-8.12.9.
From sendmail's RELEASE_NOTES:
8.12.9/8.12.9 2003/03/29
SECURITY: Fix a buffer overflow in address parsing due to
a char to int conversion problem which is potentially
remotely exploitable. Problem found by Michal Zalewski.
Note: an MTA that is not patched might be vulnerable to
data that it receives from untrusted sources, which
includes DNS.
(* Security fix *)
