[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.
