An update for ffmpeg is now available for openEuler-22.03-LTS-SP4 Security Advisory openeuler-security@openeuler.org openEuler security committee openEuler-SA-2026-3085 Final 1.0 1.0 2026-07-19 Initial 2026-07-19 2026-07-19 openEuler SA Tool V1.0 2026-07-19 ffmpeg security update An update for ffmpeg is now available for openEuler-22.03-LTS-SP4 FFmpeg is a complete and free Internet live audio and video broadcasting solution for Linux/Unix. It also includes a digital VCR. It can encode in real time in many formats including MPEG1 audio and video, MPEG4, h263, ac3, asf, avi, real, mjpeg, and flash. Security Fix(es): 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-2023-6603) 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 https://github.com/FFmpeg/FFmpeg/commit/b5b6391d64807578ab872dc58fb8aa621dcfc38a This issue was discovered by: Simcha Kosman(CVE-2025-0518) A NULL pointer dereference vulnerability exists in FFmpeg’s 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-2025-10256) 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 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-2025-7700) A heap buffer overflow in the av_bprint_finalize() function of FFmpeg v8.0.1 allows attackers to cause a Denial of Service (DoS) via a crafted input.(CVE-2026-30999) A flaw was found in FFmpeg. A remote attacker could exploit this vulnerability by providing a specially crafted MPEG-PS/VOB media file containing a malicious DVD subtitle stream. This vulnerability is caused by a signed integer overflow in the DVD subtitle parser's fragment reassembly bounds checks, leading to a heap out-of-bounds write. Successful exploitation can result in a denial of service (DoS) due to an application crash, and potentially lead to arbitrary code execution.(CVE-2026-6385) An update for ffmpeg is now available for openEuler-20.03-LTS-SP4/openEuler-22.03-LTS-SP3/openEuler-22.03-LTS-SP4/openEuler-24.03-LTS/openEuler-24.03-LTS-Next/openEuler-24.03-LTS-SP1/openEuler-24.03-LTS-SP2/openEuler-24.03-LTS-SP3/openEuler-24.03-LTS-SP4. openEuler Security has rated this update as having a security impact of high.
