RHSA-2009:1075: Moderate: httpd security update
The Apache HTTP Server is a popular and freely-available Web server.A flaw was found in the handling of compression structures between modssland OpenSSL. If too many connections were opened in a short period of time,all system memory and swap space would be consumed by httpd, negativelyimpacting other processes, or causing a system crash. (CVE-2008-1678)Note: The CVE-2008-1678 issue did not affect Red Hat Enterprise Linux 5prior to 5.3. The problem was introduced via the RHBA-2009:0181 errata inRed Hat Enterprise Linux 5.3, which upgraded OpenSSL to the newer 0.9.8eversion.A flaw was found in the handling of the "Options" and "AllowOverride"directives. In configurations using the "AllowOverride" directive withcertain "Options=" arguments, local users were not restricted fromexecuting commands from a Server-Side-Include script as intended.(CVE-2009-1195)All httpd users should upgrade to these updated packages, which containbackported patches to resolve these issues.
