{"id":"AZL-13653","summary":"CVE-2023-23916 affecting package curl for versions less than 7.88.1-1","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":"2026-04-01T05:07:44.569637Z","published":"2023-02-23T20:15:13Z","upstream":["CVE-2023-23916"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2023-23916"}],"affected":[{"package":{"name":"curl","ecosystem":"Azure Linux:2","purl":"pkg:rpm/azure-linux/curl"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"7.88.1-1"}]}],"database_specific":{"source":"https://github.com/microsoft/AzureLinuxVulnerabilityData/blob/main/osv/AZL-13653.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:H"}]}
