{"id":"OESA-2026-3876","summary":"ffmpeg security update","details":"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.\r\n\r\nSecurity Fix(es):\n\nA flaw was found in FFmpeg. This vulnerability allows unexpected additional CPU load and storage consumption, potentially leading to degraded performance or denial of service via the demuxing of arbitrary data as XBIN-formatted data without proper format validation.(CVE-2023-6604)\n\nOut of bounds read in FFmpeg in Google Chrome prior to 150.0.7871.47 allowed a remote attacker to obtain potentially sensitive information from process memory via a crafted video file. (Chromium security severity: Medium)(CVE-2026-13858)\n\nA flaw was found in FFmpeg. The tdsc_load_cursor() function writes beyond the bounds of a heap-allocated buffer when processing crafted TDSC cursor data. A remote attacker could exploit this by supplying a specially crafted video file, potentially leading to a denial of service or arbitrary code execution.(CVE-2026-18393)\n\nA flaw was found in FFmpeg. An integer overflow in the `libavfilter/vf_scale.c` component allows attackers to cause a Denial of Service (DoS) by supplying a specially crafted video file. This can lead to the application becoming unresponsive or crashing.(CVE-2026-38343)\n\nA flaw was found in FFmpeg. This vulnerability involves a NULL pointer dereference within the `get_min_buffer_size` function when processing specially crafted video files. An attacker could exploit this by providing a malicious video file, leading to a Denial of Service (DoS). A Denial of Service attack prevents legitimate users from accessing a service or resource.(CVE-2026-38344)\n\nA flaw was found in FFmpeg. An integer overflow vulnerability in the `yuv2planeX_8_c()` function allows a remote attacker to cause a Denial of Service (DoS) by supplying a specially crafted video file. This can lead to the application becoming unresponsive or crashing, impacting system availability.(CVE-2026-38346)\n\nA flaw was found in FFmpeg. A heap overflow vulnerability exists in the `ff_sws_alphablendaway` function. This flaw allows attackers to cause a Denial of Service (DoS) by providing a specially crafted input. Successful exploitation could lead to the application becoming unresponsive or crashing.(CVE-2026-38347)\n\nA flaw was found in FFmpeg, specifically within the libswscale/utils.c component. An integer overflow vulnerability allows a remote attacker to cause a Denial of Service (DoS) by supplying a specially crafted image file. This could lead to the application becoming unresponsive or crashing.(CVE-2026-38348)\n\nA flaw was found in FFmpeg. An integer overflow vulnerability in the `hScale16To19_c()` function allows a remote attacker to cause a Denial of Service (DoS) by supplying a specially crafted image file. This can lead to the application becoming unresponsive or crashing, preventing legitimate users from accessing the service.(CVE-2026-38349)","modified":"2026-09-20T13:30:21.787516005Z","published":"2026-09-20T13:22:49Z","upstream":["CVE-2023-6604","CVE-2026-13858","CVE-2026-18393","CVE-2026-38343","CVE-2026-38344","CVE-2026-38346","CVE-2026-38347","CVE-2026-38348","CVE-2026-38349"],"database_specific":{"severity":"High"},"references":[{"type":"ADVISORY","url":"https://www.openeuler.org/zh/security/security-bulletins/detail/?id=openEuler-SA-2026-3876"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2023-6604"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-13858"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-18393"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-38343"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-38344"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-38346"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-38347"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-38348"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-38349"}],"affected":[{"package":{"name":"ffmpeg","ecosystem":"openEuler:24.03-LTS-SP3","purl":"pkg:rpm/openEuler/ffmpeg&distro=openEuler-24.03-LTS-SP3"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"6.1.1-51.oe2403sp3"}]}],"ecosystem_specific":{"x86_64":["ffmpeg-6.1.1-51.oe2403sp3.x86_64.rpm","ffmpeg-debuginfo-6.1.1-51.oe2403sp3.x86_64.rpm","ffmpeg-debugsource-6.1.1-51.oe2403sp3.x86_64.rpm","ffmpeg-devel-6.1.1-51.oe2403sp3.x86_64.rpm","ffmpeg-libs-6.1.1-51.oe2403sp3.x86_64.rpm","libavdevice-6.1.1-51.oe2403sp3.x86_64.rpm"],"aarch64":["ffmpeg-6.1.1-51.oe2403sp3.aarch64.rpm","ffmpeg-debuginfo-6.1.1-51.oe2403sp3.aarch64.rpm","ffmpeg-debugsource-6.1.1-51.oe2403sp3.aarch64.rpm","ffmpeg-devel-6.1.1-51.oe2403sp3.aarch64.rpm","ffmpeg-libs-6.1.1-51.oe2403sp3.aarch64.rpm","libavdevice-6.1.1-51.oe2403sp3.aarch64.rpm"],"src":["ffmpeg-6.1.1-51.oe2403sp3.src.rpm"]},"database_specific":{"source":"https://repo.openeuler.org/security/data/osv/OESA-2026-3876.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H"}]}
