Security Fix
- CVE-2011-3368
- It was discovered that the Apache HTTP Server did not properly validate the request URI for proxied requests. In certain configurations, if a reverse proxy used the ProxyPassMatch directive, or if it used the RewriteRule directive with the proxy flag, a remote attacker could make the proxy connect to an arbitrary server, possibly disclosing sensitive information from internal web servers not directly accessible to the attacker.
Red Hat would like to thank Context Information Security for reporting this issue.
Bug Fix
- BZ#736593, BZ#736594
- The fix for CVE-2011-3192 provided by the RHSA-2011:1245 update introduced regressions in the way httpd handled certain Range HTTP header values. This update corrects those regressions.
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.
Updated httpd packages that fix one security issue are now available for Red Hat Enterprise Linux 4, 5, and 6.

Security Fix
- CVE-2011-3192
- A flaw was found in the way the Apache HTTP Server handled Range HTTP headers. A remote attacker could use this flaw to cause httpd to use an excessive amount of memory and CPU time via HTTP requests with a specially-crafted Range header.
All httpd users should upgrade to these updated packages, which contain a backported patch to correct this issue. After installing the updated packages, the httpd daemon must be restarted for the update to take effect.
Updated httpd packages that fix several bugs and add various enhancements are now available for Red Hat Enterprise Linux 5.
The Apache HTTP Server ("httpd") is the namesake project of The Apache Software Foundation.
Bug Fixes
- BZ#700322
- In situations when httpd could not allocate memory, httpd sometimes terminated unexpectedly with a segmentation fault rather than terminating the process with an error message. With this update, a patch has been applied to correct this bug and httpd no longer crashes in the scenario described.
- BZ#767990
- When the "SSLCryptoDevice" config variable in "ssl.conf" was set to an unknown or invalid value, the httpd daemon would terminate unexpectedly with a segmentation fault at startup. With this update the code has been corrected, httpd no longer crashes, and httpd issues an appropriate error message in this scenario.
Enhacements
- BZ#677279
- The rotatelogs program now provides a new "rotatelogs -c" option to create log files for each set interval, even if empty.
- BZ#677288
