gzip LHZ denial of service
| gzip-lhz-dos (29046) |  Low Risk |
Description:
gzip is vulnerable to a denial of service attack caused by improper handling of certain LHZ compressed files. By creating a specially-crafted LHZ compressed file, a remote attacker could exploit this vulnerability and cause the application to enter an infinite loop, if the attacker could convince the victim to open the malicious file.
