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...

gzip: gzip: Information disclosure via global buffer overflow in LZH decompression

A flaw was found in GNU gzip. This global buffer overflow vulnerability in the LZH decompression logic is caused by improper reuse of shared global state between different decompression formats. An attacker can exploit this by providing a specially crafted LZW file followed by a specially crafted...
