    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.
