When aborting, libcurl inadvertently does not free all the previously allocated headers and instead leaks the memory.  Further, this error condition fails silently and is therefore not easily detected by an application.","published":"2024-03-27T08:15:41.000Z","lastModified":"2026-10-15T01:17:44.000Z","status":"Modified","sourceIdentifier":"2499f714-1537-4658-8207-48ae4bb9eae9","cvss":{"version":"3.1","score":8.6,"severity":"HIGH","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:L/A:L"},"cwe":["CWE-772"],"affected":["haxx/curl","apple/macos","fedoraproject/fedora","netapp/active iq unified manager","netapp/ontap select deploy administration utility","netapp/brocade fabric operating system","netapp/bootstrap os","netapp/h300s firmware","netapp/h410s firmware","netapp/h500s firmware","netapp/h610c firmware","netapp/h610s firmware","netapp/h615c firmware","netapp/h700s firmware"],"epss":{"score":0.36081,"percentile":0.98476,"date":"2026-11-03","history":[]},"kev":{"listed":false},"exploits":{"count":0,"verified":false,"firstPublished":null,"source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[]},"verdict":{"level":"urgent","text":"EPSS puts the probability of exploitation in the next 30 days at 36.1%, higher than 98% of all known CVEs.
