{"id":"AZL-43204","summary":"CVE-2024-3651 affecting package python-idna for versions less than 3.7-1","details":"A vulnerability was identified in the kjd/idna library, specifically within the `idna.encode()` function, affecting version 3.6. The issue arises from the function's handling of crafted input strings, which can lead to quadratic complexity and consequently, a denial of service condition. This vulnerability is triggered by a crafted input that causes the `idna.encode()` function to process the input with considerable computational load, significantly increasing the processing time in a quadratic manner relative to the input size.","modified":"2026-04-21T04:30:56.272244Z","published":"2024-07-07T18:15:09Z","upstream":["CVE-2024-3651"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2024-3651"}],"affected":[{"package":{"name":"python-idna","ecosystem":"Azure Linux:3","purl":"pkg:rpm/azure-linux/python-idna"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"3.7-1"}]}],"database_specific":{"source":"https://github.com/microsoft/AzureLinuxVulnerabilityData/blob/main/osv/AZL-43204.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H"}]}
