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.","state":0,"publishedAt":"2022-07-07T00:00:00+00:00","modifiedAt":"2026-10-14T16:38:24.524+00:00","affected":[{"ecosystem":"Vendor product","name":"https://github.com/curl/curl","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"n/a\",\n                    \"product\": \"https://github.com/curl/curl\",\n                    \"versions\": [\n                        {\n                            \"version\": \"Fixed in 7.84.0\",\n                            \"status\": \"affected\"\n                        }\n                    ]\n                }"}],"metrics":[],"references":["https://hackerone.com/reports/1570651","https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/BEV6BR4MTI3CEWK2YU2HQZUW5FAS3FEY/","https://www.debian.org/security/2022/dsa-5197","https://lists.debian.org/debian-lts-announce/2022/08/msg00017.html","https://security.netapp.com/advisory/ntap-20220915-0003/","https://support.apple.com/kb/HT213488","http://seclists.org/fulldisclosure/2022/Oct/41","http://seclists.org/fulldisclosure/2022/Oct/28","https://cert-portal.siemens.com/productcert/pdf/ssa-333517.pdf","https://security.gentoo.org/glsa/202212-01","http://www.openwall.com/lists/oss-security/2023/02/15/3"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2022-32206","license":"CVE Program Terms of Use","key":"cve-program:CVE-2022-32206","identifiers":["CVE-2022-32206"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
