Summary

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.
