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."}],"affected":[{"vendor":"n/a","product":"https://github.com/curl/curl","versions":[{"version":"Fixed in 7.88.0","status":"affected"}]}],"references":[{"url":"https://hackerone.com/reports/1826048"},{"name":"[debian-lts-announce] 20230224 [SECURITY] [DLA 3341-1] curl security update","tags":["mailing-list"],"url":"https://lists.debian.org/debian-lts-announce/2023/02/msg00035.html"},{"name":"FEDORA-2023-94df30cbec","tags":["vendor-advisory"],"url":"https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/BQKE6TXYDHOTFHLTBZ5X73GTKI7II5KO/"},{"name":"DSA-5365","tags":["vendor-advisory"],"url":"https://www.debian.org/security/2023/dsa-5365"},{"url":"https://security.netapp.com/advisory/ntap-20230309-0006/"},{"name":"GLSA-202310-12","tags":["vendor-advisory"],"url":"https://security.gentoo.org/glsa/202310-12"}],"problemTypes":[{"descriptions":[{"type":"CWE","lang":"en","description":"Allocation of Resources Without Limits or Throttling (CWE-770)","cweId":"CWE-770"}]}]},"adp":[{"providerMetadata":{"orgId":"af854a3a-2127-422b-91ae-364da2661108","shortName":"CVE","dateUpdated":"2024-08-02T10:42:26.847Z"},"title":"CVE Program Container","references":[{"url":"https://hackerone.com/reports/1826048","tags":["x_transferred"]},{"name":"[debian-lts-announce] 20230224 [SECURITY] [DLA 3341-1] curl security update","tags":["mailing-list","x_transferred"],"url":"https://lists.debian.org/debian-lts-announce/2023/02/msg00035.html"},{"name":"FEDORA-2023-94df30cbec","tags":["vendor-advisory","x_transferred"],"url":"https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/BQKE6TXYDHOTFHLTBZ5X73GTKI7II5KO/"},{"name":"DSA-5365","tags":["vendor-advisory","x_transferred"],"url":"https://www.debian.org/security/2023/dsa-5365"},{"url":"https://security.netapp.com/advisory/ntap-20230309-0006/","tags":["x_transferred"]},{"name":"GLSA-202310-12","tags":["vendor-advisory","x_transferred"],"url":"https://security.gentoo.org/glsa/202310-12"}]},{"problemTypes":[{"descriptions":[{"type":"CWE","cweId":"CWE-770","lang":"en","description":"CWE-770 Allocation of Resources Without Limits or Throttling"}]}],"metrics":[{"cvssV3_1":{"scope":"UNCHANGED","version":"3.1","baseScore":6.5,"attackVector":"NETWORK","baseSeverity":"MEDIUM","vectorString":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:H","integrityImpact":"NONE","userInteraction":"REQUIRED","attackComplexity":"LOW","availabilityImpact":"HIGH","privilegesRequired":"NONE","confidentialityImpact":"NONE"}},{"other":{"type":"ssvc","content":{"timestamp":"2025-03-12T18:24:35.695221Z","id":"CVE-2023-23916","options":[{"Exploitation":"poc"},{"Automatable":"no"},{"Technical Impact":"partial"}],"role":"CISA Coordinator","version":"2.0.3"}}}],"title":"CISA ADP Vulnrichment","providerMetadata":{"orgId":"134c704f-9b21-4f2e-91b3-4a467353bcc0","shortName":"CISA-ADP","dateUpdated":"2025-03-12T18:25:23.845Z"}}]}}
