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:
 [link moved to references]
 (* 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).
