{"id":"JLSEC-2026-404","details":"An allocation of resources without limits or throttling vulnerability exists in curl \u003cv7.88.0 based on the \"chained\" HTTP compression algorithms, meaning that a server response can be compressed multiple times and potentially with differentalgorithms. 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.","modified":"2026-05-04T13:16:18.855647Z","published":"2026-05-04T13:12:06.605Z","upstream":["CVE-2023-23916"],"database_specific":{"sources":[{"html_url":"https://nvd.nist.gov/vuln/detail/CVE-2023-23916","database_specific":{"status":"Modified"},"imported":"2026-05-02T08:39:46.650Z","published":"2023-02-23T20:15:13.777Z","id":"CVE-2023-23916","modified":"2025-03-12T19:15:36.367Z","url":"https://services.nvd.nist.gov/rest/json/cves/2.0?cveId=CVE-2023-23916"}],"license":"CC-BY-4.0"},"references":[{"type":"WEB","url":"https://hackerone.com/reports/1826048"},{"type":"WEB","url":"https://hackerone.com/reports/1826048"},{"type":"WEB","url":"https://lists.debian.org/debian-lts-announce/2023/02/msg00035.html"},{"type":"WEB","url":"https://lists.debian.org/debian-lts-announce/2023/02/msg00035.html"},{"type":"WEB","url":"https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/BQKE6TXYDHOTFHLTBZ5X73GTKI7II5KO/"},{"type":"WEB","url":"https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/BQKE6TXYDHOTFHLTBZ5X73GTKI7II5KO/"},{"type":"WEB","url":"https://security.gentoo.org/glsa/202310-12"},{"type":"WEB","url":"https://security.gentoo.org/glsa/202310-12"},{"type":"WEB","url":"https://security.netapp.com/advisory/ntap-20230309-0006/"},{"type":"WEB","url":"https://security.netapp.com/advisory/ntap-20230309-0006/"},{"type":"WEB","url":"https://www.debian.org/security/2023/dsa-5365"},{"type":"WEB","url":"https://www.debian.org/security/2023/dsa-5365"}],"affected":[{"package":{"name":"CURL_jll","ecosystem":"Julia","purl":"pkg:julia/CURL_jll?uuid=b21e61f3-bafc-59ac-ab14-4c5c62d6588d"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"},{"fixed":"8.5.0+0"}]}],"database_specific":{"source":"https://github.com/JuliaLang/SecurityAdvisories.jl/tree/generated/osv/2026/JLSEC-2026-404.json"}},{"package":{"name":"LibCURL_jll","ecosystem":"Julia","purl":"pkg:julia/LibCURL_jll?uuid=deac9b47-8bc7-5906-a0fe-35ac56dc84c0"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"},{"fixed":"7.88.1+0"}]}],"database_specific":{"source":"https://github.com/JuliaLang/SecurityAdvisories.jl/tree/generated/osv/2026/JLSEC-2026-404.json"}}],"schema_version":"1.7.5"}
