RHSA-2010:0659 - Moderate: httpd security and bug fix update

Synopsis

Moderate: httpd security and bug fix update

Type/Severity

Security Advisory Moderate

Topic

Updated httpd packages that fix two security issues and multiple bugs 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.

Description

The Apache HTTP Server is a popular web server.

A flaw was discovered in the way the mod_proxy module of the Apache HTTP Server handled the timeouts of requests forwarded by a reverse proxy to the back-end server. If the proxy was configured to reuse existing back-end connections, it could return a response intended for another user under certain timeout conditions, possibly leading to information disclosure. (CVE-2010-2791)

A flaw was found in the way the mod_dav module of the Apache HTTP Server handled certain requests. If a remote attacker were to send a carefully crafted request to the server, it could cause the httpd child process to crash. (CVE-2010-1452)

This update also fixes the following bugs:

• numerous issues in the INFLATE filter provided by mod_deflate. "Inflate error -5 on flush" errors may have been logged. This update upgrades mod_deflate to the newer upstream version from Apache HTTP Server 2.2.15. (BZ#625435)

• the response would be corrupted if mod_filter applied the DEFLATE filter to a resource requiring a subrequest with an internal redirect. (BZ#625451)

• the OID() function used in the mod_ssl "SSLRequire" directive did not correctly evaluate extensions of an unknown type. (BZ#625452)

All httpd users should upgrade to these updated packages, which contain backported patches to correct these issues. After installing the updated packages, the httpd daemon must be restarted for the update to take effect.
