RHSA-2010:0175 - Low: httpd security, bug fix, and enhancement update

Synopsis

Low: httpd security, bug fix, and enhancement update

Type/Severity

Security Advisory Low

Topic

Updated httpd packages that fix one security issue, a bug, and add an enhancement are now available for Red Hat Enterprise Linux 4.

The Red Hat Security Response Team has rated this update as having low security impact. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available from the CVE link in the References section.

Description

The Apache HTTP Server is a popular web server.

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 fixes the following bug:

  • a bug was found in the mod_dav module. If a PUT request for an existing file failed, that file would be unexpectedly deleted and a "Could not get next bucket brigade" error logged. With this update, failed PUT requests no longer cause mod_dav to delete files, which resolves this issue. (BZ#572932)

As well, this update adds the following enhancement:

  • with the updated openssl packages from RHSA-2010:0163 installed, mod_ssl will refuse to renegotiate a TLS/SSL connection with an unpatched client that does not support RFC 5746. This update adds the "SSLInsecureRenegotiation" configuration directive. If this directive is enabled, mod_ssl will renegotiate insecurely with unpatched clients. (BZ#575805)

Refer to the following Red Hat Knowledgebase article for more details about the changed mod_ssl behavior: http://kbase.redhat.com/faq/docs/DOC-20491

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