Package        : nasm
Vulnerability  : buffer overflow
Problem-Type   : local
Debian-specific: no
CVE ID         : CAN-2004-1287
Debian Bug     : 285889

Jonathan Rockway discovered a buffer overflow in nasm, the
general-purpose x86 assembler, which could lead to the execution of
arbitrary code when compiling a maliciously crafted assembler source
file.

For the stable distribution (woody) this problem has been fixed in
version 0.98.28cvs-1woody2.

For the unstable distribution (sid) this problem has been fixed in
version 0.98.38-1.1.

We recommend that you upgrade your nasm package.
