When calculating the content path in handling of MPEG-DASH manifests, there's an out-of-bounds NUL-byte write one byte past the end of the buffer.When we call xmlNodeGetContent below [0], it returns a buffer precisely allocated to match the string length, using strdup internally. If this buffer is not an empty string, it is assigned to root_url at [1].If the last (non-NUL) byte in this buffer is not '/' then we append '/' in-place at [2]. This will write two bytes into the buffer, starting at the last valid byte in the buffer, writing the NUL byte beyond the end of the allocated buffer. We recommend upgrading to version 8.0 or beyond.

    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.

There are packages installed that are affected by multiple vulnerabilities referenced in the following CVEs:

  - A vulnerability, which was classified as critical, was found in FFmpeg up to 7.1. This affects the
    function ff_aac_search_for_tns of the file libavcodec/aacenc_tns.c of the component AAC Encoder. The
    manipulation leads to stack-based buffer overflow. It is possible to initiate the attack remotely. The
    exploit has been disclosed to the public and may be used. (CVE-2025-1594)

  - A flaw was found in FFmpeg's TTY Demuxer. This vulnerability allows possible data exfiltration via
    improper parsing of non-TTY-compliant input files in HLS playlists. (CVE-2023-6602)

  - A flaw was found in FFmpeg. This vulnerability allows unexpected additional CPU load and storage
    consumption, potentially leading to degraded performance or denial of service via the demuxing of
    arbitrary data as XBIN-formatted data without proper format validation. (CVE-2023-6604)

  - A flaw was found in FFmpeg's DASH playlist support. This vulnerability allows arbitrary HTTP GET requests
    to be made on behalf of the machine running FFmpeg via a crafted DASH playlist containing malicious URLs.
    (CVE-2023-6605)

  - Unchecked Return Value, Out-of-bounds Read vulnerability in FFmpeg allows Read Sensitive Constants Within
    an Executable. This vulnerability is associated with program files
    https://github.Com/FFmpeg/FFmpeg/blob/master/libavfilter/af_pan.C . This issue affects FFmpeg: 7.1. Issue
    was fixed: https://github.com/FFmpeg/FFmpeg/commit/b5b6391d64807578ab872dc58fb8aa621dcfc38a
