A vulnerability has been found in TeamSpeak Server (affected version unknown) and classified as problematic. This vulnerability affects an unknown functionality of the component qlz Library. The manipulation with an unknown input leads to a heap-based overflow vulnerability. The CWE definition for the vulnerability is CWE-122. A heap overflow condition is a buffer overflow, where the buffer that can be overwritten is allocated in the heap portion of memory, generally meaning that the buffer was allocated using a routine such as malloc(). As an impact it is known to affect confidentiality.
The weakness was presented 08/12/2016 by Hanz Jenson as not defined mailinglist post (Full-Disclosure). The advisory is shared for download at seclists.org. The public release happened without coordination with the vendor. The exploitation appears to be easy. The attack can be initiated remotely. No form of authentication is required for a successful exploitation. Technical details are unknown but a private exploit is available. The advisory points out:
The ts3 server compresses command packets with the "qlz" library. However a known vulnerability resides in one of the older versions of this library. This was already fixed in the newest qlz release (a beta release). However the ts3 server uses an older version of this library.
It is declared as proof-of-concept. The advisory illustrates:
But it's straightforward to find for anyone looking at qlz's source code. You don't need any fancy "software analyzer" to find it, like in that silly blog post.
There is no information about possible countermeasures known. It may be suggested to replace the affected object with an alternative product.
