In Netwide Assembler (NASM) 2.14rc0, there is an illegal address access in the function find_cc() in asm/preproc.c that will cause a remote denial of service attack, because pointers associated with skip_white_ calls are not validated.
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.
