Package        : roundcube
Version        : 0.3.1-6+deb6u1
CVE ID         : CVE-2015-8770

High-Tech Bridge Security Research Lab discovered a path traversal 
vulnerability in a popular webmail client Roundcube. Vulnerability can be 
exploited to gain access to sensitive information and under certain 
circumstances to execute arbitrary code and totally compromise the 
vulnerable server.

The vulnerability exists due to insufficient sanitization of "_skin" HTTP 
POST parameter in "/index.php" script when changing between different 
skins of the web application. A remote authenticated attacker can use path 
traversal sequences (e.g. "../../") to load a new skin from arbitrary 
location on the system, readable by the webserver.



(sorry for first uploading a package with a wrong version 0.3.1-6+dab6u1)
