The number of acceptable \"links\" in this \"decompression chain\" wascapped, but the cap was implemented on a per-header basis allowing a maliciousserver to insert a virtually unlimited number of compression steps simply byusing many headers. The use of such a decompression chain could result in a \"malloc bomb\", making curl end up spending enormous amounts of allocated heap memory, or trying to and returning out of memory errors.","state":0,"publishedAt":"2023-02-23T00:00:00+00:00","modifiedAt":"2026-10-14T22:32:01.283+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 7.88.0\",\n                            \"status\": \"affected\"\n                        }\n                    ]\n                }"}],"metrics":[],"references":["https://hackerone.com/reports/1826048","https://lists.debian.org/debian-lts-announce/2023/02/msg00035.html","https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/BQKE6TXYDHOTFHLTBZ5X73GTKI7II5KO/","https://www.debian.org/security/2023/dsa-5365","https://security.netapp.com/advisory/ntap-20230309-0006/","https://security.gentoo.org/glsa/202310-12"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2023-23916","license":"CVE Program Terms of Use","key":"cve-program:CVE-2023-23916","identifiers":["CVE-2023-23916"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
