CVE-2017-17818
In Netwide Assembler (NASM) 2.14rc0, there is a heap-based buffer over-read that will cause a remote denial of service attack, related to a while loop in paste_tokens in asm/preproc.c.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (2.72%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
