{"id":"AZL-74772","summary":"CVE-2026-0990 affecting package libxml2 for versions less than 2.10.4-10","details":"A flaw was found in libxml2, an XML parsing library. This uncontrolled recursion vulnerability occurs in the xmlCatalogXMLResolveURI function when an XML catalog contains a delegate URI entry that references itself. A remote attacker could exploit this configuration-dependent issue by providing a specially crafted XML catalog, leading to infinite recursion and call stack exhaustion. This ultimately results in a segmentation fault, causing a Denial of Service (DoS) by crashing affected applications.","modified":"2026-04-21T04:38:47.623578Z","published":"2026-01-15T15:15:52Z","upstream":["CVE-2026-0990"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-0990"}],"affected":[{"package":{"name":"libxml2","ecosystem":"Azure Linux:2","purl":"pkg:rpm/azure-linux/libxml2"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2.10.4-10"}]}],"database_specific":{"source":"https://github.com/microsoft/AzureLinuxVulnerabilityData/blob/main/osv/AZL-74772.json"}}],"schema_version":"1.7.5"}
