gzip: gzip: Arbitrary file overwrite via insecure temporary file handling in gzexe utility

A flaw was found in the gzexe utility of GNU gzip. When the mktemp utility is not available, gzexe creates temporary files with predictable names based on the process ID. A local attacker can exploit this by pre-creating a symbolic link to an arbitrary file at the predicted temporary file path...
