Summary

Mini-XML 4.0.0 through 4.0.6 contains an off-by-one stack out-of-bounds write in mxml_strtod() when the locale decimal point is not '.'. Attackers can supply XML with a 63-digit REAL value followed by '.' to write a NUL byte past the 64-byte stack buffer, corrupting stack memory or crashing the process.

Fencer Vulns keeps one entry per vulnerability: the CVE id wins, then GHSA, and records that alias each other are merged, except that two CVEs always keep separate entries. The same data is available as JSON.

CPEs and fixed versions use Anchore's correction of NVD's data: Added CPE configurations because not yet analyzed by NVD.
