CVE-2008-2719 (http://nvd.nist.gov/nvd.cfm?cvename=CVE-2008-2719): Off-by-one error in the ppscan function (preproc.c) in Netwide Assembler (NASM) 2.02 allows context-dependent attackers to cause a denial of service (crash) and possibly execute arbitrary code via a crafted file that triggers a stack-based buffer overflow.
hm... 2.03 is in the tree already... closing (leaving cc and whiteboard since I had already mostly filled it ;-)
