Doc Text:
A flaw was found in FFmpeg. An attacker could cause a Denial of Service (DoS) by convincing a user or automated service to process a specially crafted image file. When converting the image to the DPX format, missing validation of raw sample parameters triggers an invalid memory access (NULL pointer dereference), causing the application to crash.

Description OSIDB Bzimport 2026-11-10 20:12:12 UTC
FFmpeg through 9.0.2 contains a NULL pointer dereference vulnerability in libavcodec/dpxenc.c that allows attackers to crash the process via unvalidated bits_per_raw_sample for RGB48 input. Attackers can supply a 12-bit RGB image, such as JPEG 2000, that when transcoded to DPX selects encode_gbrp12() and dereferences NULL plane pointers, causing denial of service.
