This is the first I've heard of it.  I just examined the code, and 
inflate_fast() and inffixed.h are properly rigged to detect and reject 
invalid codes, at least in 1.1.3 and 1.1.4.  It must be a previous 
version of zlib that has this problem, assuming that the problem has 
been correctly described.  Can someone find out what version they're 
talking about, so I'll know where to look?
