Detailsinfo

A vulnerability classified as very critical has been found in VideoLAN VLC Media Player up to 2.0.1 (Multimedia Player Software). Affected is some unknown functionality of the component Access Plugin. The manipulation as part of a Real RTSP Stream leads to a memory corruption vulnerability. CWE is classifying the issue as CWE-119. The product performs operations on a memory buffer, but it can read from or write to a memory location that is outside of the intended boundary of the buffer. This is going to have an impact on confidentiality, integrity, and availability. CVE summarizes:

Multiple heap-based buffer overflows in VideoLAN VLC media player before 2.0.1 allow remote attackers to cause a denial of service (application crash) or possibly execute arbitrary code via a crafted Real RTSP stream.

The weakness was published 03/15/2012 (Website). The advisory is shared for download at videolan.org. The public release has been coordinated with the vendor. This vulnerability is traded as CVE-2012-1776 since 03/19/2012. The exploitability is told to be difficult. It is possible to launch the attack remotely. The exploitation doesn't require any form of authentication. Technical details are unknown but a public exploit is available. The current price for an exploit might be approx. USD $0-$5k (estimation calculated on 03/22/2021).

A public exploit has been developed in Ruby. The exploit is shared for download at securityfocus.com. It is declared as proof-of-concept. The vulnerability was handled as a non-public zero-day exploit for at least 3 days. During that time the estimated underground price was around $0-$5k. The vulnerability scanner Nessus provides a plugin with the ID 62114 (FreeBSD : vlc -- arbitrary code execution in Real RTSP and MMS support (62f36dfd-ff56-11e1-8821-001b2134ef46)), which helps to determine the existence of the flaw in a target environment. It is assigned to the family FreeBSD Local Security Checks. The commercial vulnerability scanner Qualys is able to test this issue with plugin 120497 (VLC Media Player Multiple Remote Code Execution Vulnerabilities (VideoLAN-SA-1201) (VideoLAN-SA-1202)).

Upgrading to version 2.0.1 eliminates this vulnerability. A possible mitigation has been published immediately after the disclosure of the vulnerability.

The vulnerability is also documented in the databases at X-Force (74118), Tenable (62114), SecurityFocus (BID 52550†), OSVDB (80189†) and Secunia (SA48503†). Similar entry is available at VDB-4859. Once again VulDB remains the best source for vulnerability data.
