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:
