Description Vlad K. 2018-06-28 22:40:46 UTC
"Netwide Assembler (NASM) 2.13.02rc2 has a heap-based buffer over-read in the function tokenize in asm/preproc.c, related to an unterminated string."

* Fixed upstream:
  http://repo.or.cz/nasm.git/commit/3144e84add8b152cc7a71e44617ce6f21daa4ba3

* Upstream bug report:
  https://bugzilla.nasm.us/show_bug.cgi?id=3392446

Looks like currently stable dev-lang/nasm-2.13.01 is vulnerable. I have not checked other stable versions.
