{"id":"ALPINE-CVE-2022-32206","details":"curl \u003c 7.84.0 supports \"chained\" HTTP compression algorithms, meaning that a serverresponse can be compressed multiple times and potentially with different algorithms. The number of acceptable \"links\" in this \"decompression chain\" was unbounded, allowing a malicious server to insert a virtually unlimited number of compression steps.The use of such a decompression chain could result in a \"malloc bomb\", makingcurl end up spending enormous amounts of allocated heap memory, or trying toand returning out of memory errors.","modified":"2026-08-27T22:18:01.743019479Z","published":"2022-07-07T13:15:08.340Z","upstream":["CVE-2022-32206"],"references":[{"type":"ADVISORY","url":"https://security.alpinelinux.org/vuln/CVE-2022-32206"}],"affected":[{"package":{"name":"curl","ecosystem":"Alpine:v3.13","purl":"pkg:apk/alpine/curl?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"7.79.1-r2"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2022-32206.json"}},{"package":{"name":"curl","ecosystem":"Alpine:v3.14","purl":"pkg:apk/alpine/curl?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"7.79.1-r2"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2022-32206.json"}},{"package":{"name":"curl","ecosystem":"Alpine:v3.15","purl":"pkg:apk/alpine/curl?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"7.80.0-r2"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2022-32206.json"}},{"package":{"name":"curl","ecosystem":"Alpine:v3.16","purl":"pkg:apk/alpine/curl?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"7.83.1-r2"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2022-32206.json"}},{"package":{"name":"curl","ecosystem":"Alpine:v3.17","purl":"pkg:apk/alpine/curl?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"7.84.0-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2022-32206.json"}},{"package":{"name":"curl","ecosystem":"Alpine:v3.18","purl":"pkg:apk/alpine/curl?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"7.84.0-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2022-32206.json"}},{"package":{"name":"curl","ecosystem":"Alpine:v3.19","purl":"pkg:apk/alpine/curl?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"7.84.0-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2022-32206.json"}},{"package":{"name":"curl","ecosystem":"Alpine:v3.20","purl":"pkg:apk/alpine/curl?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"7.84.0-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2022-32206.json"}},{"package":{"name":"curl","ecosystem":"Alpine:v3.21","purl":"pkg:apk/alpine/curl?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"7.84.0-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2022-32206.json"}},{"package":{"name":"curl","ecosystem":"Alpine:v3.22","purl":"pkg:apk/alpine/curl?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"7.84.0-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2022-32206.json"}},{"package":{"name":"curl","ecosystem":"Alpine:v3.23","purl":"pkg:apk/alpine/curl?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"7.84.0-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2022-32206.json"}},{"package":{"name":"curl","ecosystem":"Alpine:v3.24","purl":"pkg:apk/alpine/curl?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"7.84.0-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2022-32206.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:H"}]}
