gzip -N command directory traversal
| gzip-n-directory-traversal (20199) |  Medium Risk |
Description:
gzip (GNU zip) could allow a remote attacker to traverse directories on system. If an attacker could persuade a user to open a malicious compressed file using the 'gunzip -N' command, the attacker could traverse directories and create or overwrite files on the system with the privileges of the victim.
Consequences:
File Manipulation
