[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). +--------------------------+

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
