{"id":"ALPINE-CVE-2020-15254","details":"Crossbeam is a set of tools for concurrent programming. In crossbeam-channel before version 0.4.4, the bounded channel incorrectly assumes that `Vec::from_iter` has allocated capacity that same as the number of iterator elements. `Vec::from_iter` does not actually guarantee that and may allocate extra memory. The destructor of the `bounded` channel reconstructs `Vec` from the raw pointer based on the incorrect assumes described above. This is unsound and causing deallocation with the incorrect capacity when `Vec::from_iter` has allocated different sizes with the number of iterator elements. This has been fixed in crossbeam-channel 0.4.4.","modified":"2026-11-03T06:32:30.901130987Z","published":"2020-10-16T17:15:12.057Z","upstream":["CVE-2020-15254"],"references":[{"type":"ADVISORY","url":"https://security.alpinelinux.org/vuln/CVE-2020-15254"}],"affected":[{"package":{"name":"firefox","ecosystem":"Alpine:v3.12","purl":"pkg:apk/alpine/firefox?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"82.0-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2020-15254.json"}},{"package":{"name":"firefox","ecosystem":"Alpine:v3.13","purl":"pkg:apk/alpine/firefox?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"82.0-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2020-15254.json"}},{"package":{"name":"firefox","ecosystem":"Alpine:v3.14","purl":"pkg:apk/alpine/firefox?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"82.0-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2020-15254.json"}},{"package":{"name":"firefox","ecosystem":"Alpine:v3.15","purl":"pkg:apk/alpine/firefox?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"82.0-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2020-15254.json"}},{"package":{"name":"firefox","ecosystem":"Alpine:v3.16","purl":"pkg:apk/alpine/firefox?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"82.0-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2020-15254.json"}},{"package":{"name":"firefox","ecosystem":"Alpine:v3.17","purl":"pkg:apk/alpine/firefox?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"82.0-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2020-15254.json"}},{"package":{"name":"firefox","ecosystem":"Alpine:v3.18","purl":"pkg:apk/alpine/firefox?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"82.0-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2020-15254.json"}},{"package":{"name":"firefox","ecosystem":"Alpine:v3.19","purl":"pkg:apk/alpine/firefox?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"82.0-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2020-15254.json"}},{"package":{"name":"firefox","ecosystem":"Alpine:v3.20","purl":"pkg:apk/alpine/firefox?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"82.0-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2020-15254.json"}},{"package":{"name":"firefox","ecosystem":"Alpine:v3.21","purl":"pkg:apk/alpine/firefox?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"82.0-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2020-15254.json"}},{"package":{"name":"firefox","ecosystem":"Alpine:v3.22","purl":"pkg:apk/alpine/firefox?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"82.0-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2020-15254.json"}},{"package":{"name":"firefox","ecosystem":"Alpine:v3.23","purl":"pkg:apk/alpine/firefox?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"82.0-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2020-15254.json"}},{"package":{"name":"librewolf","ecosystem":"Alpine:v3.21","purl":"pkg:apk/alpine/librewolf?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"82.0-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2020-15254.json"}},{"package":{"name":"librewolf","ecosystem":"Alpine:v3.22","purl":"pkg:apk/alpine/librewolf?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"82.0-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2020-15254.json"}},{"package":{"name":"librewolf","ecosystem":"Alpine:v3.23","purl":"pkg:apk/alpine/librewolf?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"82.0-r0"}]}],"ecosystem_specific":{},"d
