Detailsinfo

A vulnerability, which was classified as problematic, was found in GStreamer (Multimedia Processing Software) (the affected version is unknown). Affected is an unknown code of the component vmnc Decoder. The manipulation with an unknown input leads to a information disclosure vulnerability. CWE is classifying the issue as CWE-200. The product exposes sensitive information to an actor that is not explicitly authorized to have access to that information. This is going to have an impact on confidentiality. CVE summarizes:

The vmnc decoder in the gstreamer does not initialize the render canvas, which allows remote attackers to obtain sensitive information as demonstrated by thumbnailing a simple 1 frame vmnc movie that does not draw to the allocated render canvas.

The bug was discovered 11/18/2016. The weakness was disclosed 01/23/2017 by Chris Evans (Website). The advisory is available at openwall.com. This vulnerability is traded as CVE-2016-9446 since 11/18/2016. It is possible to launch the attack remotely. The exploitation doesn't require any form of authentication. The technical details are unknown and an exploit is not available. This vulnerability is assigned to T1592 by the MITRE ATT&CK project.

The vulnerability was handled as a non-public zero-day exploit for at least 1 days. During that time the estimated underground price was around $0-$5k. The vulnerability scanner Nessus provides a plugin with the ID 94983 (Debian DLA-712-1 : gst-plugins-bad0.10 security update), which helps to determine the existence of the flaw in a target environment. It is assigned to the family Debian Local Security Checks and running in the context l. The commercial vulnerability scanner Qualys is able to test this issue with plugin 169466 (SUSE Enterprise Linux Security Update for gstreamer-plugins-bad (SUSE-SU-2016:3297-1)).
