CONECTIVA LINUX SECURITY ANNOUNCEMENT 
- --------------------------------------------------------------------------

PACKAGE   : sendmail
SUMMARY   : Remote vulnerability
DATE      : 2003-09-18 15:56:00
ID        : CLA-2003:742
RELEVANT
RELEASES  : 7.0, 8, 9

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

DESCRIPTION
 Sendmail[1] is a widely used Mail Transfer Agent (MTA).
 
 Michal Zalewski reported[2] a remote vulnerability[3] in sendmail
 versions 8.12.9 and earlier. The problem resides in the address
 parsing code and can be exploited to execute arbitrary code in the
 context of the server. The Common Vulnerabilities and Exposures
 project (cve.mitre.org) has assigned the name CAN-2003-0694 to this
 issue[4].
 
 The sendmail authors have released a new version[5], 8.12.10, which
 fixes this vulnerability. They have also made available a patch[6]
 for older versions, which the packages provided via this announcement
 contain.
 
 This update also includes fixes for a buffer overflow vulnerability
 in the ruleset parsing code. This vulnerability is not exploitable in
 the default configuration and requires the use of non-standard
 rulesets recipients. The Common Vulnerabilities and Exposures project
 (cve.mitre.org) has assigned the name CAN-2003-0681 to this
 issue[7].
 
 Starting with Conectiva Linux 7.0, sendmail is no longer the default
 mail server and has been replaced with Postfix (but sendmail is still
 shipped with all Conectiva Linux versions).


SOLUTION
 All sendmail users should upgrade immediately. If the service is
 already active, it should be restarted after the upgrade in order to
 close the vulnerability. To do so, execute the following command as
 root:
 
 /sbin/service sendmail restart
