{"id":"ALPINE-CVE-2017-14056","details":"In libavformat/rl2.c in FFmpeg 3.3.3, a DoS in rl2_read_header() due to lack of an EOF (End of File) check might cause huge CPU and memory consumption. When a crafted RL2 file, which claims a large \"frame_count\" field in the header but does not contain sufficient backing data, is provided, the loops (for offset and size tables) would consume huge CPU and memory resources, since there is no EOF check inside these loops.","modified":"2026-11-03T06:30:46.477704384Z","published":"2017-08-31T15:29:00.373Z","upstream":["CVE-2017-14056"],"references":[{"type":"ADVISORY","url":"https://security.alpinelinux.org/vuln/CVE-2017-14056"}],"affected":[{"package":{"name":"ffmpeg","ecosystem":"Alpine:v3.10","purl":"pkg:apk/alpine/ffmpeg?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"3.3.4-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2017-14056.json"}},{"package":{"name":"ffmpeg","ecosystem":"Alpine:v3.11","purl":"pkg:apk/alpine/ffmpeg?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"3.3.4-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2017-14056.json"}},{"package":{"name":"ffmpeg","ecosystem":"Alpine:v3.12","purl":"pkg:apk/alpine/ffmpeg?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"3.3.4-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2017-14056.json"}},{"package":{"name":"ffmpeg","ecosystem":"Alpine:v3.13","purl":"pkg:apk/alpine/ffmpeg?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"3.3.4-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2017-14056.json"}},{"package":{"name":"ffmpeg","ecosystem":"Alpine:v3.14","purl":"pkg:apk/alpine/ffmpeg?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"3.3.4-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2017-14056.json"}},{"package":{"name":"ffmpeg","ecosystem":"Alpine:v3.15","purl":"pkg:apk/alpine/ffmpeg?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"3.3.4-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2017-14056.json"}},{"package":{"name":"ffmpeg","ecosystem":"Alpine:v3.16","purl":"pkg:apk/alpine/ffmpeg?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"3.3.4-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2017-14056.json"}},{"package":{"name":"ffmpeg","ecosystem":"Alpine:v3.17","purl":"pkg:apk/alpine/ffmpeg?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"3.3.4-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2017-14056.json"}},{"package":{"name":"ffmpeg","ecosystem":"Alpine:v3.18","purl":"pkg:apk/alpine/ffmpeg?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"3.3.4-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2017-14056.json"}},{"package":{"name":"ffmpeg","ecosystem":"Alpine:v3.19","purl":"pkg:apk/alpine/ffmpeg?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"3.3.4-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2017-14056.json"}},{"package":{"name":"ffmpeg","ecosystem":"Alpine:v3.20","purl":"pkg:apk/alpine/ffmpeg?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"3.3.4-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2017-14056.json"}},{"package":{"name":"ffmpeg","ecosystem":"Alpine:v3.21","purl":"pkg:apk/alpine/ffmpeg?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"3.3.4-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2017-14056.json"}},{"package":{"name":"ffmpeg","ecosystem":"Alpine:v3.22","purl":"pkg:apk/alpine/ffmpeg?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"3.3.4-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2017-14056.json"}},{"package":{"name":"ffmpeg","ecosystem":"Alpine:v3.23","purl":"pkg:apk/alpine/ffmpeg?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"3.3.4-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2017-14056.json"}},{"package":{"name":"ffmpeg","ecosystem":"Alpine:v3.24","purl":"pkg:apk/alpine/ffmpeg?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"3.3.4-r0"}]}],"ecosystem_specific":{},"database_specific":{"source"
