Vulnerability Assessment Details

RHSA-2004-342: httpd

Vulnerability Assessment Summary
Check for the version of the httpd packages

Detailed Explanation for this Vulnerability Assessment

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 ( has assigned the name
CVE-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 permited 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 ( has assigned the name CVE-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.
