An update for ffmpeg is now available for openEuler-24.03-LTS-SP3 Security Advisory openeuler-security@openeuler.org openEuler security committee openEuler-SA-2026-2662 Final 1.0 1.0 2026-06-12 Initial 2026-06-12 2026-06-12 openEuler SA Tool V1.0 2026-06-12 ffmpeg security update An update for ffmpeg is now available for openEuler-24.03-LTS-SP3 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): 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.(CVE-2025-59728) An update for ffmpeg is now available for openEuler-24.03-LTS-SP3. openEuler Security has rated this update as having a security impact of high.
