Here are the details from the Slackware 10.1 ChangeLog:
+--------------------------+
patches/packages/zlib-1.2.2-i486-2.tgz: Patched an overflow in zlib that
could cause applications using zlib to crash. The overflow does not
involve user supplied data, and therefore does not allow the execution of
arbitrary code. However, it could still be used by a remote attacker to
create a denial of service.
For more information, see:

(* Security fix *)
