Juniper ScreenOS 5.4 < 5.4.0r28 / 6.2 < 6.2.0r18 / 6.3 < 6.3.0r16 Malformed ICMP Echo Request DoS (JSA10604)

high Nessus Plugin ID 74367

Language:

Synopsis

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

Description

The remote host is running a version of Juniper ScreenOS prior to 5.4.0r28 / 6.2.0r18 / 6.3.0r16. It is, therefore, affected by a denial of service vulnerability due to a failure to properly handle ICMP echo request packets.

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

Note that the host is not affected if the 'Ping of Death' screen is enabled.

Solution

Upgrade to 5.4.0r28 / 6.2.0r18 / 6.3.0r16 or later or apply the workaround.
