Security Fixes
- CVE-2012-4558
- Cross-site scripting (XSS) flaws were found in the mod_proxy_balancer module's manager web interface. If a remote attacker could trick a user, who was logged into the manager web interface, into visiting a specially-crafted URL, it would lead to arbitrary web script execution in the context of the user's manager interface session.
- CVE-2013-1862
- It was found that mod_rewrite did not filter terminal escape sequences from its log file. If mod_rewrite was configured with the RewriteLog directive, a remote attacker could use specially-crafted HTTP requests to inject terminal escape sequences into the mod_rewrite log file. If a victim viewed the log file with a terminal emulator, it could result in arbitrary command execution with the privileges of that user.
- CVE-2012-3499
- Cross-site scripting (XSS) flaws were found in the mod_info, mod_status, mod_imagemap, mod_ldap, and mod_proxy_ftp modules. An attacker could possibly use these flaws to perform XSS attacks if they were able to make the victim's browser generate an HTTP request with a specially-crafted Host header.

Bug Fix
- BZ#974162
- Due to a bug in the mod_mem_cache module, child processes sometimes terminated unexpectedly with a segmentation fault while using the threaded "worker" Multi-Processing Modules (MPM) (/usr/sbin/httpd.worker). This update fixes mod_mem_cache to repair thread-safety issues, and crashes no longer occur in the described scenario.
Users of httpd are advised to upgrade to these updated packages, which fix this bug. After installing the updated packages, the httpd daemon will be restarted automatically.
