CVE-2026-125180
FFmpeg 8.1 through 9.0.2 EXIF Parser Memory Exhaustion via Overlapping Tags
Description
FFmpeg 8.1 through 9.0.2 contains a memory exhaustion vulnerability in the libavcodec/exif.c parser that allows attackers to amplify allocations by pointing many IFD entries at overlapping payloads. Attackers can embed a small crafted EXIF block in TIFF, JPEG, PNG or WebP images to trigger quadratic memory allocation, causing denial of service in decoding applications.
