A vulnerability classified as problematic has been found in FFmpeg up to 3.2.5/3.3.2 (Multimedia Processing Software). This affects an unknown code block of the component MOV File Handler. The manipulation with an unknown input leads to a null pointer dereference vulnerability. CWE is classifying the issue as CWE-476. A NULL pointer dereference occurs when the application dereferences a pointer that it expects to be valid, but is NULL, typically causing a crash or exit. This is going to have an impact on availability. The summary by CVE is:

The dnxhd decoder in FFmpeg before 3.2.6, and 3.3.x before 3.3.3 allows remote attackers to cause a denial of service (NULL pointer dereference) via a crafted mov file.

The bug was discovered 08/14/2017. The weakness was presented 12/27/2017 (oss-sec). It is possible to read the advisory at openwall.com. This vulnerability is uniquely identified as CVE-2017-9608 since 06/13/2017. It is possible to initiate the attack remotely. No form of authentication is needed for exploitation. It demands that the victim is doing some kind of user interaction. The technical details are unknown and an exploit is not publicly available.
