RHSA-2004:342: httpd security update



Updated httpd packages that fix a buffer overflow in mod_ssl and a remotely triggerable memory leak are now available.

The Apache HTTP server is a powerful, full-featured, efficient, and freely-available Web server. A stack buffer overflow was discovered in mod_ssl that could be triggered if using the FakeBasicAuth option. If mod_ssl was sent a client certificate with a subject DN field longer than 6000 characters, a stack overflow occured if FakeBasicAuth had been enabled. In order to exploit this issue the carefully crafted malicious certificate would have had to be signed by a Certificate Authority which mod_ssl is configured to trust. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CAN-2004-0488 to this issue. A remotely triggered memory leak in the Apache HTTP Server earlier than version 2.0.50 was also discovered. This allowed a remote attacker to perform a denial of service attack against the server by forcing it to consume large amounts of memory. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CAN-2004-0493 to this issue. Users of the Apache HTTP server should upgrade to these updated packages, which contain backported patches that address these issues.
