Discovering Copies of Zlib

Everybody running a linux machine needs to update their copy of the zlib libarary. If your application is dynamically linked, you’re golden – yum -y update . If you have a statically linked zlib in one or more of your applications, you have to know about it, and how do you do that?

Well, it turns out the zlib author is quite clever and inserts a version string in the binary for each version. But which tool do you use for searching a system full of binaries for specific strings? Why, a virus scanner, of course.
