The FoFiType1C::convertToType0 function in FoFiType1C.cc in Poppler 0.59.0 has a NULL pointer dereference vulnerability because a data structure is not initialized, which allows an attacker to launch a denial of service attack.
A NULL pointer dereference occurs when the application dereferences a pointer that it expects to be valid, but is NULL, typically causing a crash or exit.
