Detail

Problem Description:

Updated httpd packages that fix two security issues and add an enhancement are now available for Red Hat Enterprise Linux 5.

The Red Hat Security Response Team has rated this update as having moderate security impact. Common Vulnerability Scoring System (CVSS) base scores, which give detailed severity ratings, are available for each vulnerability from the CVE links in the References section.

2. Relevant releases/architectures:

RHEL Desktop Workstation (v. 5 client) - i386, x86_64 Red Hat Enterprise Linux (v. 5 server) - i386, ia64, ppc, s390x, x86_64 Red Hat Enterprise Linux Desktop (v. 5 client) - i386, x86_64

3. Description:

The Apache HTTP Server is a popular web server.

It was discovered that mod_proxy_ajp incorrectly returned an "Internal Server Error" response when processing certain malformed requests, which caused the back-end server to be marked as failed in configurations where mod_proxy is used in load balancer mode. A remote attacker could cause mod_proxy to not send requests to back-end AJP (Apache JServ Protocol) servers for the retry timeout period (60 seconds by default) by sending specially-crafted requests. (CVE-2010-0408)

A use-after-free flaw was discovered in the way the Apache HTTP Server handled request headers in subrequests. In configurations where subrequests are used, a multithreaded MPM (Multi-Processing Module) could possibly leak information from other requests in request replies. (CVE-2010-0434)

This update also adds the following enhancement:

* with the updated openssl packages from RHSA-2010:0162 installed, mod_ssl will refuse to renegotiate a TLS/SSL connection with an unpatched client that does not support RFC 574

Title: USN-908-1 -- apache2 vulnerabilities
Description: It was discovered that mod_proxy_ajp did not properly handle errors when a client doesn�t send a request body. A remote attacker could exploit this with a crafted request and cause a denial of service. This issue affected Ubuntu 8.04 LTS, 8.10, 9.04 and 9.10. It was discovered that Apache did not properly handle headers in subrequests under certain conditions. A remote attacker could exploit this with a crafted request and possibly obtain sensitive information from previous requests

Title: DSA-2035-1 apache2 -- multiple issues
Description: Two issues have been found in the Apache HTTPD web server: CVE-2010-0408 mod_proxy_ajp would return the wrong status code if it encountered an error, causing a backend server to be put into an error state until the retry timeout expired. A remote attacker could send malicious requests to trigger this issue, resulting in denial of service. CVE-2010-0434 A flaw in the core subrequest process code was found, which could lead to a daemon crash or disclosure of sensitive information if the headers of a subrequest were modified by modules such as mod_headers. For the stable distribution, these problems have been fixed in version 2.2.9-10+lenny7. For the testing distribution and the unstable distribution, these problems have been fixed in version 2.2.15-1. This advisory also provides updated apache2-mpm-itk packages which have been recompiled against the new apache2 packages. We recommend that you upgrade your apache2 and apache2-mpm-itk packages.
