Description

This update fixes several security issues in the Apache2 webserver.

  • This update also includes several fixes for a mod_proxy reverse exposure via RewriteRule or ProxyPassMatch directives. (CVE-2011-3639 / CVE-2011-3368 / CVE-2011-4317)

  • Fixed the SSL renegotiation DoS by disabling renegotiation by default. (CVE-2011-1473)

  • Integer overflow in ap_pregsub function resulting in a heap-based buffer overflow could potentially allow local attackers to gain privileges. (CVE-2011-3607)

Also a non-security bug was fixed :

  • httpd-2.2.x-bnc727071-mod_authnz_ldap-utf8.diff: make non-ascii eg UTF8 passwords work with mod_authnz_ldap. [bnc#727071]
