Juniper ScreenOS 6.3 < 6.3.0r17 DoS

high Nessus Plugin ID 74149

Language:

Synopsis

The remote host is affected by a denial of service vulnerability.

Description

The remote host is running a version of Juniper ScreenOS 6.3 prior to 6.3.0r17. It is, therefore, affected by a denial of service vulnerability due to a failure to properly handle SSL/TLS protocol packets.

A remote, unauthenticated attacker could potentially exploit this vulnerability by sending malformed SSL/TLS packets to cause a firewall crash or failover. Repeated exploitation can result in an extended denial of service condition.

Solution

Upgrade to 6.3.0r17 or later.
