CVE-2026-70631

FFmpeg vulnerable before 9.0: uninitialized heap memory read in the TIFF decoder (libavcodec/tiff.c) when decoding a crafted TIFF with a Deflate strip; tiff_unpack_zlib() allocates a full declared strip buffer but copies bytes unconditionally, exposing stale heap data in output. No remediation de...
