The obviously effective thing to do would be to just view it...
more(1), even ee(8) et al. will do the trick. You'll find the version
in the $FreeBSD$ tag near the top of the file, after the license.
If you want to be keen about it, use ident(1). See below.

Very likely what you're talking about is the Jan 4th pw(8) security
advisory, which actually refers to the source file "pwupd.c", which is
part of the pw binary build in /usr/src/usr.sbin/pw/. I would do this:
ryan $ ident /usr/src/usr.sbin/pw/pwupd.c
/usr/src/usr.sbin/pw/pwupd.c:
$FreeBSD: src/usr.sbin/pw/pwupd.c,v 1.12.2.4 2001/12/21 15:21:32 nectar Exp $
So, the version is immediately after the RCS filename, and is 1.12.2.4
in this case. I can also tell it was updated on December 21st, which
was the correction date mentioned in the advisory. So, my pw sources
have been updated to the fixed versions.
Don't forget to rebuild the affected parts after updating the source.
See the advisory itself for the hand-held approach to patching. :-)
Good luck,
- Ryan
