[mew-dist 23519] zlib 1.1.4 vulnerability

[Kazu Yamamoto ( 山本和彦 )]

Hello,

As you may know a security hole have been found in zlib 1.1.4:
	http://www.securityfocus.com/bid/6913

Since bin/mewencode is linked with the zlib, I investigate this.
Because mewencode does NOT use gzprintf(), I believe mewencode is NOT
vulnerable.

Of course, upgrading of zlib is a good thing, anyway, though zlib
1.1.5 is not available at this moment.
