RHEL 3 : httpd (RHSA-2004:342)

Synopsis :

The remote Red Hat host is missing one or more security updates.

Description :

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-based 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 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 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 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.
