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.\r\n\r\nSecurity Fix(es):\n\nA use-after-free vulnerability was found in FFmpeg's RASC video decoder. The decode_move() function initializes a read pointer into a decompressed buffer, but a subsequent reallocation of that same buffer during move-table processing leaves the pointer dangling. An attacker could exploit this by providing a specially crafted AVI file containing a malicious RASC video stream. When a user opens or plays the file, the decoder reads from freed heap memory, which could lead to a denial of service (crash).(CVE-2026-12706)","affected":[{"package":{"ecosystem":"openEuler:24.03-LTS-SP3","name":"ffmpeg","purl":"pkg:rpm/openEuler/ffmpeg&distro=openEuler-24.03-LTS-SP3"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"6.1.1-33.oe2403sp3"}]}],"ecosystem_specific":{"aarch64":["ffmpeg-6.1.1-33.oe2403sp3.aarch64.rpm","ffmpeg-debuginfo-6.1.1-33.oe2403sp3.aarch64.rpm","ffmpeg-debugsource-6.1.1-33.oe2403sp3.aarch64.rpm","ffmpeg-devel-6.1.1-33.oe2403sp3.aarch64.rpm","ffmpeg-libs-6.1.1-33.oe2403sp3.aarch64.rpm","libavdevice-6.1.1-33.oe2403sp3.aarch64.rpm"],"src":["ffmpeg-6.1.1-33.oe2403sp3.src.rpm"],"x86_64":["ffmpeg-6.1.1-33.oe2403sp3.x86_64.rpm","ffmpeg-debuginfo-6.1.1-33.oe2403sp3.x86_64.rpm","ffmpeg-debugsource-6.1.1-33.oe2403sp3.x86_64.rpm","ffmpeg-devel-6.1.1-33.oe2403sp3.x86_64.rpm","ffmpeg-libs-6.1.1-33.oe2403sp3.x86_64.rpm","libavdevice-6.1.1-33.oe2403sp3.x86_64.rpm"]}}],"references":[{"type":"ADVISORY","url":"https://www.openeuler.org/zh/security/security-bulletins/detail/?id=openEuler-SA-2026-2828"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-12706"}],"database_specific":{"severity":"Medium"}}
