Description
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.
