gzip

gzip (GNU zip) is a compression utility designed to be a replacement for 'compress'. Its main advantages over compress are much better compression and freedom from patented algorithms. The GNU Project uses it as the standard compression program for its system.

            gzip buffer overflow revision
            I laud the speed with which the buffer overflow problem was addressed, but the revision.h file has not been altered to reflect this change. While this is an administrative-only event, it makes it impossible to identify which version of gzip is in use.

            It really needs fixed, guys.
