[slackware-security]  apache+mod_ssl  (SSA:2004-305-01)

New apache packages are available for Slackware 8.1, 9.0, 9.1, 10.0,
and -current to fix a security issue.  Apache has been upgraded to
version 1.3.33 which fixes a buffer overflow which may allow local
users to execute arbitrary code as the apache user.

The mod_ssl package has also been upgraded to version 2.8.22_1.3.33.

More details about this issue may be found in the Common
Vulnerabilities and Exposures (CVE) database:

   http://cve.mitre.org/cgi-bin/cvename.cgi?name=CAN-2004-0940


Here are the details from the Slackware 10.0 ChangeLog:
+--------------------------+
patches/packages/apache-1.3.33-i486-1.tgz:  Upgraded to apache-1.3.33.
  This fixes one new security issue (the first issue, CAN-2004-0492, was fixed
  in apache-1.3.33).  The second bug fixed in 1.3.3 (CAN-2004-0940) allows a
  local user who can create SSI documents to become "nobody".  The amount of
  mischief they could cause as nobody seems low at first glance, but it might
  allow them to use kill or killall as nobody to try to create a DoS.
  Mention PHP's mhash dependency in httpd.conf (thanks to Jakub Jankowski).
  (* Security fix *)
patches/packages/mod_ssl-2.8.22_1.3.33-i486-1.tgz:  Upgraded to
  mod_ssl-2.8.22_1.3.33.

Installation instructions:
+------------------------+

First, stop apache:

# apachectl stop

Next, upgrade the Apache package as root:

# upgradepkg apache-1.3.33-i486-1.tgz

For mod_ssl users, IMPORTANT:  Backup any keys/certificates you wish
to save for mod_ssl (in /etc/apache/ssl.*), then upgrade mod_ssl:

# upgradepkg mod_ssl-2.8.22_1.3.33-i486-1.tgz

If necessary, restore any mod_ssl config files.

Finally, restart apache:

# apachectl start

Or, if you're running a secure server with mod_ssl:

# apachectl startssl
