Hello

it went over several newstickers yesterday, there is a bug
in zlib-1.1.3. Certain input confuses the memory management
of zlib, which leads to crashes or worse, might lead to the
execution of arbitrary code.

The full description is on:

http://www.gzip.org/zlib/advisory-2002-03-11.txt

There is a new version zlib-1.1.4, which fixes this problem.
Unfortunatly there are some programs, which are statically linked 
to zlib, they have to be recompiled too.
For a list of programs linking to zlib:

Redhat has allready patches, including a patched kernel
(kernel ppp compression is also using zlib):

This issue might be important enough for 8.2 final, although
many packages will be touched. Fixing it via patches leaves a
bad taste, you buy the latest Mandrake and the first thing to do
is updating a bunch of RPMs.

I'm writing this here, because I did not see any postings to this 
issue 'til now (maybe I missed something) and the zlib on my
mirror still is version zlib-1.1.3-19mdk.src.rpm.

I hope you will find a good solution.
