Doc Text:
A flaw was found in FFmpeg. This vulnerability allows an attacker to cause an information disclosure by providing a specially crafted, truncated run-length encoded (RLE) Targa (TGA) image file for processing. Due to missing packet length checks during decompression, decoded output frames retain leftover data from uninitialized memory. An attacker could exploit this flaw to view residual memory contents, potentially exposing sensitive information.

Description OSIDB Bzimport 2026-11-10 13:02:41 UTC
FFmpeg through 9.0.2 contains an uninitialized memory disclosure vulnerability in targa_decode_rle() in libavcodec/targa.c caused by missing packet length checks. Attackers can supply truncated RLE-compressed TGA images so decoded frames contain leftover heap buffer data and replicated uninitialized stack bytes.
