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)\n\nAn out-of-bounds write vulnerability in FFmpeg's libavcodec library, specifically in the MagicYUV decoder, allows denial-of-service and, in some cases, can be exploited for remote code execution.\n\n This vulnerability is associated with the file libavcodec/magicyuv.C.\n\n\n\nThis issue affects FFmpeg before version 8.1.2.(CVE-2026-8461)","affected":[{"package":{"ecosystem":"openEuler:20.03-LTS-SP4","name":"ffmpeg","purl":"pkg:rpm/openEuler/ffmpeg&distro=openEuler-20.03-LTS-SP4"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"4.2.4-39.oe2003sp4"}]}],"ecosystem_specific":{"aarch64":["ffmpeg-4.2.4-39.oe2003sp4.aarch64.rpm","ffmpeg-debuginfo-4.2.4-39.oe2003sp4.aarch64.rpm","ffmpeg-debugsource-4.2.4-39.oe2003sp4.aarch64.rpm","ffmpeg-devel-4.2.4-39.oe2003sp4.aarch64.rpm","ffmpeg-libs-4.2.4-39.oe2003sp4.aarch64.rpm","libavdevice-4.2.4-39.oe2003sp4.aarch64.rpm"],"src":["ffmpeg-4.2.4-39.oe2003sp4.src.rpm"],"x86_64":["ffmpeg-4.2.4-39.oe2003sp4.x86_64.rpm","ffmpeg-debuginfo-4.2.4-39.oe2003sp4.x86_64.rpm","ffmpeg-debugsource-4.2.4-39.oe2003sp4.x86_64.rpm","ffmpeg-devel-4.2.4-39.oe2003sp4.x86_64.rpm","ffmpeg-libs-4.2.4-39.oe2003sp4.x86_64.rpm","libavdevice-4.2.4-39.oe2003sp4.x86_64.rpm"]}}],"references":[{"type":"ADVISORY","url":"https://www.openeuler.org/zh/security/security-bulletins/detail/?id=openEuler-SA-2026-2829"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-12706"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-8461"}],"database_specific":{"severity":"High"}}
