{"id":"AZL-47020","summary":"CVE-2024-6874 affecting package curl for versions less than 8.8.0-1","details":"libcurl's URL API function\n[curl_url_get()](https://curl.se/libcurl/c/curl_url_get.html) offers punycode\nconversions, to and from IDN. Asking to convert a name that is exactly 256\nbytes, libcurl ends up reading outside of a stack based buffer when built to\nuse the *macidn* IDN backend. The conversion function then fills up the\nprovided buffer exactly - but does not null terminate the string.\n\nThis flaw can lead to stack contents accidently getting returned as part of\nthe converted string.","modified":"2026-04-01T05:16:57.304972Z","published":"2024-07-24T08:15:03Z","upstream":["CVE-2024-6874"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2024-6874"}],"affected":[{"package":{"name":"curl","ecosystem":"Azure Linux:3","purl":"pkg:rpm/azure-linux/curl"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"8.8.0-1"}]}],"database_specific":{"source":"https://github.com/microsoft/AzureLinuxVulnerabilityData/blob/main/osv/AZL-47020.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:N/A:N"}]}
