(RHSA-2013:0815) Moderate: httpd security update

The Apache HTTP Server is a popular web server.

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-2012-4558)

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-2013-1862)

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. (CVE-2012-3499)

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 will be restarted automatically.
