A Use After Free vulnerability in function new_Token in asm/preproc.c in nasm 2.14.02 allows attackers to cause a denial of service via crafted nasm command.
The product reuses or references memory after it has been freed. At some point afterward, the memory may be allocated again and saved in another pointer, while the original pointer references a location somewhere within the new allocation. Any operations using the original pointer are no longer valid because the memory "belongs" to the code that operates on the new pointer.
