RHSA-2009:1075 - Moderate: httpd security update

Synopsis

Moderate: httpd security update

Type/Severity

Security Advisory Moderate

Topic

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

This update has been rated as having moderate security impact by the Red Hat Security Response Team.

Description

The Apache HTTP Server is a popular and freely-available Web server.

A flaw was found in the handling of compression structures between mod_ssl and OpenSSL. If too many connections were opened in a short period of time, all system memory and swap space would be consumed by httpd, negatively impacting other processes, or causing a system crash. (CVE-2008-1678)

Note: The CVE-2008-1678 issue did not affect Red Hat Enterprise Linux 5 prior to 5.3. The problem was introduced via the RHBA-2009:0181 errata in Red Hat Enterprise Linux 5.3, which upgraded OpenSSL to the newer 0.9.8e version.

A flaw was found in the handling of the "Options" and "AllowOverride" directives. In configurations using the "AllowOverride" directive with certain "Options=" arguments, local users were not restricted from executing commands from a Server-Side-Include script as intended. (CVE-2009-1195)

All httpd users should upgrade to these updated packages, which contain backported patches to resolve these issues. Users must restart httpd for this update to take effect.

Solution

Before applying this update, make sure that all previously-released errata relevant to your system have been applied.

This update is available via Red Hat Network. Details on how to use the Red Hat Network to apply this update are available at This content is not included.http://kbase.redhat.com/faq/docs/DOC-11259
