FFmpeg n7.0 has a race condition vulnerability in the VP9 decoder. This could lead to a data race if video encoding parameters were being exported, as the side data would be attached in the decoder thread while being read in the output thread.

The remote Debian 11 host has packages installed that are affected by multiple vulnerabilities as referenced in the dla-4440 advisory.

    Package        : ffmpeg     Version        : 7:4.3.9-0+deb11u2     CVE ID         : CVE-2023-6603 CVE-2024-36615 CVE-2025-1594 CVE-2025-7700                      CVE-2025-9951 CVE-2025-10256 CVE-2025-63757     Debian Bug     :

    Several vulnerabilities have been discovered in the FFmpeg multimedia     framework, which could result in denial of service or potentially the     execution of arbitrary code if malformed files/streams are processed.

    CVE-2023-6603

        A flaw was found in FFmpeg's HLS playlist parsing. This vulnerability         allows a denial of service via a maliciously crafted HLS playlist that         triggers a null pointer dereference during initialization.

    CVE-2024-36615

        FFmpeg n7.0 has a race condition vulnerability in the VP9 decoder. This         could lead to a data race if video encoding parameters were being exported,         as the side data would be attached in the decoder thread while being read         in the output thread.

    CVE-2025-1594

        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-2025-7700

        A flaw was found in FFmpegs ALS audio decoder, where it does not properly         check for memory allocation failures. This can cause the application to         crash when processing certain malformed audio files. While it does not lead         to data theft or system control, it can be used to disrupt services and         cause a denial of service.

    CVE-2025-9951

        A heap-buffer-overflow write exists in jpeg2000dec FFmpeg which allows an         attacker to potentially gain remote code execution or cause denial of         service via the channel definition cdef atom of JPEG2000.

    CVE-2025-10256

        A NULL pointer dereference vulnerability exists in FFmpegs Firequalizer         filter (libavfilter/af_firequalizer.c) due to a missing check on the return         value of av_malloc_array() in the config_input() function. An attacker         could exploit this by tricking a victim into processing a crafted media         file with the Firequalizer filter enabled, causing the application to         dereference a NULL pointer and crash, leading to denial of service.

    CVE-2025-63757

        Integer overflow vulnerability in the yuv2ya16_X_c_template function in         libswscale/output.c in FFmpeg 8.0.

    For Debian 11 bullseye, these problems have been fixed in version     7:4.3.9-0+deb11u2.

    We recommend that you upgrade your ffmpeg packages.

The version of Tencent Linux installed on the remote TencentOS Server 4 host is prior to tested version. It is, therefore, affected by multiple vulnerabilities as referenced in the TSSA-2024:0511 advisory.

    Package updates are available for TencentOS Server 4 that fix the following vulnerabilities:

    CVE-2024-7055:
    A vulnerability was found in FFmpeg up to 7.0.1. It has been classified as critical. This affects the     function pnm_decode_frame in the library /libavcodec/pnmdec.c. The manipulation leads to heap-based buffer     overflow. It is possible to initiate the attack remotely. The exploit has been disclosed to the public and     may be used. Upgrading to version 7.0.2 is able to address this issue. It is recommended to upgrade the     affected component. The associated identifier of this vulnerability is VDB-273651.

    CVE-2024-36617:
    FFmpeg n6.1.1 has an integer overflow vulnerability in the FFmpeg CAF decoder.

    CVE-2024-36616:
    An integer overflow in the component /libavformat/westwood_vqa.c of FFmpeg n6.1.1 allows attackers to     cause a denial of service in the application via a crafted VQA file.

    CVE-2024-36618:
    FFmpeg n6.1.1 has a vulnerability in the AVI demuxer of the libavformat library which allows for an     integer overflow, potentially resulting in a denial-of-service (DoS) condition.

    CVE-2024-35368:
    FFmpeg n7.0 is affected by a Double Free via the rkmpp_retrieve_frame function within     libavcodec/rkmppdec.c.

    CVE-2024-36615:
    FFmpeg n7.0 has a race condition vulnerability in the VP9 decoder. This could lead to a data race if video     encoding parameters were being exported, as the side data would be attached in the decoder thread while     being read in the output thread.

    CVE-2024-36619:
    FFmpeg n6.1.1 has a vulnerability in the WAVARC decoder of the libavcodec library which allows for an     integer overflow when handling certain block types, leading to a denial-of-service (DoS) condition.

    CVE-2024-35367:
    FFmpeg n6.1.1 has an Out-of-bounds Read via libavcodec/ppc/vp8dsp_altivec.c, static const vec_s8     h_subpel_filters_outer

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

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

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - FFmpeg n7.0 has a race condition vulnerability in the VP9 decoder. This could lead to a data race if video     encoding parameters were being exported, as the side data would be attached in the decoder thread while     being read in the output thread. (CVE-2024-36615)

Note that Nessus relies on the presence of the package as reported by the vendor.
