CVE-2026-58049FFmpeg - Out-of-Bounds Write in RASC Decoder decode_dlta()

FFmpeg FFmpeg; Red Hat Red Hat Enterprise Linux AI 3.0 for RHEL 9; Red Hat Red Hat Enterprise Linux AI 3.2 for RHEL 9; Red Hat Red Hat Enterprise Linux AI 3.3 … Yayım: (4 ay önce)

Açıklama

FFmpeg's RASC video decoder (decode_dlta in libavcodec/rasc.c) performs 32-bit reads and writes at the row cursor before the NEXT_LINE row-boundary check and validates the DLTA region in pixel rather than byte units, so a DLTA run on a PAL8 frame can access several bytes past the row allocation. A crafted media stream using the RASC FourCC, decoded by libavcodec, triggers a bitstream-controlled out-of-bounds heap write and adjacent out-of-bounds read, leading to memory corruption.

Zayıflık türü (CWE): CWE-787

Veri: CVE.org, NVD, CISA KEV, FIRST EPSS, Ubuntu. Bilgiler kaynaktaki haliyle, İngilizce yayımlanır.
