|CVSS Meta Temp Score|
CVSS is a standardized scoring system to determine possibilities of attacks. The Temp Score considers temporal factors like disclosure, exploit and countermeasures. The unique Meta Score calculates the average score of different sources to provide a normalized scoring system.
|Current Exploit Price (≈)|
Our analysts are monitoring exploit markets and are in contact with vulnerability brokers. The range indicates the observed or calculated exploit price to be seen on exploit markets. A good indicator to understand the monetary effort required for and the popularity of an attack.
|CTI Interest Score|
Our Cyber Threat Intelligence team is monitoring different web sites, mailing lists, exploit markets and social media networks. The CTI Interest Score identifies the interest of attackers and the security community for this specific vulnerability in real-time. A high score indicates an elevated risk to be targeted for this vulnerability.
A vulnerability, which was classified as problematic, was found in FFmpeg 2.0 (Multimedia Processing Software). This affects the function
decode_nal_unit of the component Slice Segment Handler. The manipulation with an unknown input leads to a memory corruption vulnerability. CWE is classifying the issue as CWE-119. The software 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 availability.
The issue has been introduced in 07/11/2013. The weakness was disclosed 02/06/2014 as hevc: check that the VCL NAL types are the same for all slice segments of a frame as confirmed git commit (GIT Repository). The advisory is shared at git.videolan.org. This vulnerability is uniquely identified as CVE-2014-125019. It is possible to initiate the attack remotely. No form of authentication is needed for exploitation. Technical details are known, but no exploit is available.
The vulnerability was handled as a non-public zero-day exploit for at least 210 days. During that time the estimated underground price was around $0-$5k.
Applying a patch is able to eliminate this problem. The bugfix is ready for download at git.videolan.org. A possible mitigation has been published immediately after the disclosure of the vulnerability.
