Information

Heap out-of-bound read in ParseJSS due to missing check of string length.
Allows attacker to read heap uninitialized data (potentially beyond allocated data - depends on heap implementation).
A JSS file (e.g. one of his 200 first lines conforms to the JSS regex) that starts with ‘#’ as first char and then ‘S’ when the line is shorter than 6 characters or second character ‘T’ and line shorter then 8 characters.
example: ‘#T’
