I just stumbled across an article about a vulnerability in the zlib 
compression library at msnbc.com.  Here is the link:

http://www.msnbc.com/news/722605.asp?0si=-

It mentions that CERT will be making a statement about it, so I went 
to CERT's site and found this: http://www.kb.cert.org/vuls/id/368819
It says that FreeBSD is vulnerable as of 28-Feb-2002.  It also said 
that there was no "known" exploit code.  I'm sure that will change 
quickly now that this is public.

I went and looked at the FreeBSD CVS repository for zlib 
(http://www.freebsd.org/cgi/cvsweb.cgi/src/lib/libz/) and it appears 
that zlib 1.1.4 has been imported into the "vendor" branch.  I'm not 
familiar with the "vendor" branch.  Could someone enlighten me?

I went to the zlib site at http://www.gzip.org/zlib and found that 
zlib 1.1.4 contains the vulnerability fix, so it appears that steps 
are being taken to fix this in FreeBSD.

Anyone have any idea how long it will take to make it into RELENG_4_5?

Just curious since I have several machines to upgrade when it does.
