  Ubuntu Security Notice USN-1368-1

  Posted: February 16th, 2012, 6:34pm PST

  Tags:  ubuntu proxy security apache-http-server external-exposure proxy-module  

  Ubuntu Security Notice 1368-1 - It was discovered that the Apache HTTP Server incorrectly handled the SetEnvIf .htaccess file directive. An attacker having write access to a .htaccess file may exploit this to possibly execute arbitrary code. Prutha Parikh discovered that the mod_proxy module did not properly interact with the RewriteRule and ProxyPassMatch pattern matches in the configuration of a reverse proxy. This could allow remote attackers to contact internal webservers behind the proxy that were not intended for external exposure. Various other issues were also addressed.
