  - CVE-2012-3499
    The modules mod_info, mod_status, mod_imagemap,
    mod_ldap, and mod_proxy_ftp did not properly escape
    hostnames and URIs in HTML output, causing cross site
    scripting vulnerabilities.

  - CVE-2012-4558
    Mod_proxy_balancer did not properly escape hostnames and
    URIs in its balancer-manager interface, causing a cross
    site scripting vulnerability.

  - CVE-2013-1048
    Hayawardh Vijayakumar noticed that the apache2ctl script
    created the lock directory in an unsafe manner, allowing
    a local attacker to gain elevated privileges via a
    symlink attack. This is a Debian specific issue."
