Debian DLA-392-1 : roundcube security update

high Nessus Plugin ID 87976

Synopsis

The remote Debian host is missing a security update.

Description

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)

NOTE: Tenable Network Security has extracted the preceding description block directly from the DLA security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Solution

Upgrade the affected packages.
