{"id":"ALPINE-CVE-2025-59730","details":"When decoding a frame for a SANM file (ANIM v0 variant), the decoded data can be larger than the buffer allocated for it.\n\nFrames encoded with codec 48 can specify their resolution (width x height). A buffer of appropriate size is allocated depending on the resolution.\n\nThis codec can encode the frame contents using a run-length encoding algorithm. There are no checks that the decoded frame fits in the allocated buffer, leading to a heap-buffer-overflow.\n\nprocess_frame_obj initializes the buffers based on the frame resolution:\n\n\n\nWe recommend upgrading to version 8.0 or beyond.","modified":"2026-11-03T06:33:00.898216369Z","published":"2025-10-06T08:15:34.610Z","upstream":["CVE-2025-59730"],"references":[{"type":"ADVISORY","url":"https://security.alpinelinux.org/vuln/CVE-2025-59730"}],"affected":[{"package":{"name":"ffmpeg","ecosystem":"Alpine:v3.23","purl":"pkg:apk/alpine/ffmpeg?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"8.0-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2025-59730.json"}},{"package":{"name":"ffmpeg","ecosystem":"Alpine:v3.24","purl":"pkg:apk/alpine/ffmpeg?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"8.0-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2025-59730.json"}}],"schema_version":"1.9.2","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:A/AC:H/AT:P/PR:L/UI:P/VC:L/VI:H/VA:N/SC:L/SI:H/SA:N/E:X/CR:X/IR:X/AR:X/MAV:X/MAC:X/MAT:X/MPR:X/MUI:X/MVC:X/MVI:X/MVA:X/MSC:X/MSI:X/MSA:X/S:X/AU:X/R:X/V:X/RE:X/U:X"}]}
