It is known that if the offset to entries is pushed passed the end of the file, the system freezes, it is not known wether this is exploitable or not. Infact any change which makes it read passed the end of the file makes it crash.

It is known that if the offset to entries (size of header) is pushed passed the end of the file, the system freezes, it is not known wether this is exploitable or not. Infact any change which makes it read passed the end of the file makes it crash.
