{"id":"AZL-86550","summary":"CVE-2026-8177 affecting package perl-XML-LibXML for versions less than 2.0209-3","details":"XML::LibXML versions through 2.0210 for Perl read out-of-bounds heap memory when parsing XML node names containing truncated UTF-8 byte sequences.\n\nA node name ending in the middle of a multi byte UTF-8 sequence causes the parser to read past the end of the input string into adjacent heap memory.\n\nAny Perl process that passes attacker controlled strings to XML::LibXML's DOM node-name methods can reach this path on the default API. The likely consequence is a crash, causing denial of service.","modified":"2026-09-20T05:33:47Z","published":"2026-05-10T21:16:30Z","upstream":["CVE-2026-8177"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-8177"}],"affected":[{"package":{"name":"perl-XML-LibXML","ecosystem":"Azure Linux:3","purl":"pkg:rpm/azure-linux/perl-XML-LibXML"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2.0209-3"}]}],"database_specific":{"source":"https://github.com/microsoft/AzureLinuxVulnerabilityData/blob/main/osv/AZL-86550.json"}}],"schema_version":"1.9.0"}
