mod_ssl (SSA:2005-251-02)
Posted on: 09/09/2005 05:48 AM

New mod_ssl packages are available for Slackware 8.1, 9.0, 9.1, 10.0, 10.1, and -current to fix a security issue. If "SSLVerifyClient optional" was configured in the global section of the config file, it could improperly override "SSLVerifyClient require" in a per-location section.

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

Here are the details from the Slackware 10.1 ChangeLog:
patches/packages/mod_ssl-2.8.24_1.3.33-i486-1.tgz: Upgraded to

Fix a security issue (CAN-2005-2700) where "SSLVerifyClient require" was
not enforced in per-location context if "SSLVerifyClient optional" was

# upgradepkg mod_ssl-2.8.24_1.3.33-i486-1.tgz

If necessary, restore any mod_ssl config files.

Finally, restart apache:

# apachectl startssl
