Detailsinfo

A vulnerability classified as problematic has been found in FFmpeg up to 2.8.1 (Multimedia Processing Software). This affects the function init_tile of the file libavcodec/jpeg2000dec.c of the component JPEG 2000 Data Handler. The manipulation of the argument coordinate with an unknown input leads to a input validation vulnerability. CWE is classifying the issue as CWE-20. The product receives input or data, but it does not validate or incorrectly validates that the input has the properties that are required to process the data safely and correctly. This is going to have an impact on availability. The summary by CVE is:

The init_tile function in libavcodec/jpeg2000dec.c in FFmpeg before 2.8.2 does not enforce minimum-value and maximum-value constraints on tile coordinates, which allows remote attackers to cause a denial of service (out-of-bounds array access) or possibly have unspecified other impact via crafted JPEG 2000 data.

The weakness was disclosed 11/17/2015 as confirmed git commit (GIT Repository). It is possible to read the advisory at git.videolan.org.
