{"id":"AZL-65241","summary":"CVE-2025-24294 affecting package ruby for versions less than 3.3.5-5","details":"The attack vector is a potential Denial of Service (DoS). The vulnerability is caused by an insufficient check on the length of a decompressed domain name within a DNS packet.\r\n\r\nAn attacker can craft a malicious DNS packet containing a highly compressed domain name. When the resolv library parses such a packet, the name decompression process consumes a large amount of CPU resources, as the library does not limit the resulting length of the name.\r\n\r\nThis resource consumption can cause the application thread to become unresponsive, resulting in a Denial of Service condition.","modified":"2026-04-01T05:20:30.576051Z","published":"2025-07-12T04:15:46Z","upstream":["CVE-2025-24294"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2025-24294"}],"affected":[{"package":{"name":"ruby","ecosystem":"Azure Linux:3","purl":"pkg:rpm/azure-linux/ruby"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"3.3.5-5"}]}],"database_specific":{"source":"https://github.com/microsoft/AzureLinuxVulnerabilityData/blob/main/osv/AZL-65241.json"}}],"schema_version":"1.7.5"}
