The bundled utility allocates exactly ini_length bytes, while strip_ini_cache() unconditionally writes a NUL terminator at ini_source[ini_length], requiring an additional writable byte. Applications using the bundled allocation pattern can trigger deterministic heap memory corruption when processing any non-empty INI input, resulting in denial of service.\n\n## Remediation\n\nRefer to the linked advisories for vendor-supplied fixes and affected version ranges.","depth":"sunlit","depthScore":3,"depthScoreParts":{"impact":2.8,"likelihood":0,"exploitation":0,"ransomware":0},"changes":[]}
