gzip zgrep and bzgrep code execution

gzip-zgrep-bzgrep-code-execution (20539) The risk level is classified as MediumMedium Risk

Description:

gzip (GNU zip) could allow a remote attacker to execute arbitrary code on the vulnerable system, caused by a vulnerability in the zgrep and bzgrep utilities. By persuading a victim to run zgrep or bzgrep on a file with a specially-crafted filename, a remote attacker could exploit this vulnerability to execute arbitrary code on the vulnerable system.
