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."}],"affected":[{"source":"9b29abf9-4ab0-4765-b253-1875cd9b441e","affectedData":[{"vendor":"OALDERS","product":"HTML::Entities","defaultStatus":"unaffected","collectionURL":"https://cpan.org/modules","packageName":"HTML-Parser","programFiles":["util.c"],"programRoutines":[{"name":"HTML::Entities::_decode_entities"}],"repo":"https://github.com/libwww-perl/HTML-Parser","versions":[{"version":"0","lessThan":"3.84","versionType":"custom","status":"affected"}]}]}],"metrics":{"cvssMetricV31":[{"source":"134c704f-9b21-4f2e-91b3-4a467353bcc0","type":"Secondary","cvssData":{"version":"3.1","vectorString":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N","baseScore":7.5,"baseSeverity":"HIGH","attackVector":"NETWORK","attackComplexity":"LOW","privilegesRequired":"NONE","userInteraction":"NONE","scope":"UNCHANGED","confidentialityImpact":"HIGH","integrityImpact":"NONE","availabilityImpact":"NONE"},"exploitabilityScore":3.9,"impactScore":3.6}],"ssvcV203":[{"source":"134c704f-9b21-4f2e-91b3-4a467353bcc0","ssvcData":{"timestamp":"2026-06-04T12:59:04.771815Z","id":"CVE-2026-8829","options":[{"exploitation":"none"},{"automatable":"yes"},{"technicalImpact":"partial"}],"role":"CISA Coordinator","version":"2.0.3"}}]},"weaknesses":[{"source":"9b29abf9-4ab0-4765-b253-1875cd9b441e","type":"Secondary","description":[{"lang":"en","value":"CWE-416"}]}],"configurations":[{"nodes":[{"operator":"OR","negate":false,"cpeMatch":[{"vulnerable":true,"criteria":"cpe:2.3:a:oalders:html\\:\\:entities:*:*:*:*:*:perl:*:*","versionEndExcluding":"3.84","matchCriteriaId":"0DB42006-30BD-4085-8C4B-F9D75404315C"}]}]}],"references":[{"url":"https://github.com/libwww-perl/HTML-Parser/commit/6922552b0778c90a9587a3894e248be4d3a25e1c.patch","source":"9b29abf9-4ab0-4765-b253-1875cd9b441e","tags":["Patch"]},{"url":"https://github.com/libwww-perl/HTML-Parser/pull/56","source":"9b29abf9-4ab0-4765-b253-1875cd9b441e","tags":["Issue Tracking","Patch"]},{"url":"http://www.openwall.com/lists/oss-security/2026/06/04/2","source":"af854a3a-2127-422b-91ae-364da2661108","tags":["Mailing List","Third Party Advisory"]},{"url":"https://lists.debian.org/debian-lts-announce/2026/06/msg00044.html","source":"af854a3a-2127-422b-91ae-364da2661108"}]}}]}
