CVE-2016-2329 (GCVE-0-2016-2329)

Vulnerability from cvelistv5 – Published: 2016-02-12 02:00 – Updated: 2024-08-05 23:24

Summary

libavcodec/tiff.c in FFmpeg before 2.8.6 does not properly validate RowsPerStrip values and YCbCr chrominance subsampling factors, which allows remote attackers to cause a denial of service (out-of-bounds array access) or possibly have unspecified other impact via a crafted TIFF file, related to the tiff_decode_tag and decode_frame functions.
