FFmpeg before 8.1 has an integer overflow and resultant out-of-bounds write via CENC (Common Encryption) subsample data to libavformat/mov.c.

The remote SUSE Linux SLES15 / SLES_SAP15 host has packages installed that are affected by multiple vulnerabilities as referenced in the SUSE-SU-2026:2444-1 advisory.

    This update for ffmpeg-4 fixes the following issues

    Update to version 4.4.7:

    - CVE-2023-6601: HLS Unsafe File Extension Bypass (bsc#1220545).
    - CVE-2024-35366: FFmpeg n6.1.1 is Integer Overflow. The vulnerability exists in the parse_options     function of sbgdec.c       within the libavformat module. When parsing certain options, the software does not adequately validate     the i       (bsc#1234030).
    - CVE-2025-1594: stack-based buffer overflow in function ff_aac_search_for_tns of the file     libavcodec/aacenc_tns.c of       the component AAC Encoder (bsc#1237561).
    - CVE-2025-9951: heap-based buffer overflow in jpeg2000dec (bsc#1249393).
    - CVE-2025-10256: NULL pointer dereference in Firequalizer filter (bsc#1249431).
    - CVE-2025-63757: accumulation of filtered pixel values can lead to an integer overflow (bsc#1255392).
    - CVE-2026-30997: Denial of Service via out-of-bounds read (bsc#1262047).
    - CVE-2026-40962: inadequate CENC subsample bounds checks can lead to an integer overflow (bsc#1262237).

Tenable has extracted the preceding description block directly from the SUSE security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.
