[slackware-security]  mod_ssl (SSA:2004-154-01)

New mod_ssl packages are available for Slackware 8.1, 9.0, 9.1, and -current
to fix a security issue.  The packages were upgraded to mod_ssl-2.8.18-1.3.31
fixing a buffer overflow that may allow remote attackers to execute arbitrary
code via a client certificate with a long subject DN, if mod_ssl is
configured to trust the issuing CA.  Web sites running mod_ssl should upgrade
to the new set of apache and mod_ssl packages.  There are new PHP packages as
well to fix a Slackware-specific local denial-of-service issue (an additional
Slackware advisory SSA:2004-154-02 has been issued for PHP).

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

Here are the details from the Slackware 9.1 ChangeLog:
+--------------------------+
Wed Jun  2 11:28:17 PDT 2004
patches/packages/mod_ssl-2.8.18_1.3.31-i486-1.tgz:  Upgraded to
  mod_ssl-2.8.18-1.3.31.  This fixes a buffer overflow that may allow remote
  attackers to execute arbitrary code via a client certificate with a long
  subject DN, if mod_ssl is configured to trust the issuing CA:
    *) Fix buffer overflow in "SSLOptions +FakeBasicAuth" implementation
      if the Subject-DN in the client certificate exceeds 6KB in length.
  For more details, see:
    http://cve.mitre.org/cgi-bin/cvename.cgi?name=CAN-2004-0488
  (* Security fix *)
  Other changes:  Make the sample keys .new so as not to overwrite existing
  server keys.  However, any existing mod_ssl package will have these listed
  as non-config files, and will still remove and replace these upon upgrade.
  You'll have to save your config files one more time... sorry).

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

First, stop apache:

# apachectl stop

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

Next, upgrade these packages as root:

# upgradepkg apache-1.3.31-i486-1.tgz
# upgradepkg mod_ssl-2.8.18_1.3.31-i486-1.tgz
# upgradepkg php-4.3.6-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
