CVE-2019-6290: An infinite recursion issue was discovered in eval.c in Netwide Assembler (NASM) through 2.14.02. There is a stack exhaustion problem resulting from infinite recursion in the functions expr, rexp, bexpr and cexpr in certain scenarios involving lots of ���{��� characters. Remote attackers could leverage this vulnerability to cause a denial-of-service via a crafted asm file. CVE-2019-6291: An issue was discovered in the function expr6 in eval.c in Netwide Assembler (NASM) through 2.14.02. There is a stack exhaustion problem caused by the expr6 function making recursive calls to itself in certain scenarios involving lots of ���!��� or ���+��� or ���-��� characters. Remote attackers could leverage this vulnerability to cause a denial-of-service via a crafted asm file.
