{"id":"AZL-89451","summary":"CVE-2026-8829 affecting package perl-HTML-Parser for versions less than 3.82-2","details":"HTML::Entities versions before 3.84 for Perl read freed heap memory in _decode_entities.\n\nThe XS routine backing HTML::Entities::_decode_entities cached a pointer (repl) into the entity-value SV returned by hv_fetch on the entity2char hash. When the input SV was identical to a value SV in that hash, and that value contained its own key as an entity reference, a later call to grow_gap() reallocated the SV's PV buffer and freed the backing allocation that repl still pointed into. The subsequent copy loop read repl_len bytes from the freed allocation.\n\nThe read may disclose adjacent heap contents into the destination SV.","modified":"2026-08-30T05:26:50Z","published":"2026-06-04T03:16:20Z","upstream":["CVE-2026-8829"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-8829"}],"affected":[{"package":{"name":"perl-HTML-Parser","ecosystem":"Azure Linux:3","purl":"pkg:rpm/azure-linux/perl-HTML-Parser"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"3.82-2"}]}],"database_specific":{"source":"https://github.com/microsoft/AzureLinuxVulnerabilityData/blob/main/osv/AZL-89451.json"}}],"schema_version":"1.9.0"}
