{"id":"AZL-97524","summary":"CVE-2026-63384 affecting package mysql 8.0.46-1","details":"Libevent is an event notification library. Prior to 2.1.13 and 2.2.2-alpha, libevent has an incorrect integer conversion in event_tagging.c when evtag_unmarshal_header uses evtag_decode_int to decode an attacker-controlled uint32 payload length and returns it as a signed int. Values above INT_MAX become negative or truncated, and evtag_unmarshal_string can use the converted value in allocation sizing, producing a wrapped large allocation request and denial of service. This issue is fixed in versions 2.1.13 and 2.2.2-alpha.","modified":"2026-08-30T05:26:50Z","published":"2026-08-20T18:16:36Z","upstream":["CVE-2026-63384"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-63384"}],"affected":[{"package":{"name":"mysql","ecosystem":"Azure Linux:3","purl":"pkg:rpm/azure-linux/mysql"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"last_affected":"8.0.46-1"}]}],"database_specific":{"source":"https://github.com/microsoft/AzureLinuxVulnerabilityData/blob/main/osv/AZL-97524.json"}}],"schema_version":"1.9.0"}
