From 1.3.1.1 to before 2.2.7.4, a signed length truncation bug causes an out-of-bounds read in the default Markdown parse path. Inputs larger than INT_MAX are truncated to a signed int before entering the native parser, allowing the parser to read past the end of the supplied buffer and crash the process. This vulnerability is fixed in 2.2.7.4."}], "lastModified": "2026-04-16T04:20:29.057", "configurations": [{"nodes": [{"negate": false, "cpeMatch": [{"criteria": "cpe:2.3:a:dafoster:rdiscount:*:*:*:*:*:ruby:*:*", "vulnerable": true, "matchCriteriaId": "CD92C2DB-DEF1-4154-A725-76F41B1A0BBC", "versionEndExcluding": "2.2.7.4", "versionStartIncluding": "1.3.1.1"}], "operator": "OR"}]}], "sourceIdentifier": "security-advisories@github.com"}
