Summary

Juniper ScreenOS 6.3 and earlier allows remote attackers to cause a denial of service (crash and restart or failover) via a malformed SSL/TLS packet.

Common Weakness Enumeration (CWE)

Nessus

NASL familyFirewalls
NASL idSCREENOS_JSA10624.NASL
descriptionThe 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.
