Name of the Vulnerable Software and Affected Versions Juniper Netscreen and ScreenOS Firewall products with ScreenOS versions prior to 6.3.0r13-dnd1 Juniper Netscreen and ScreenOS Firewall products with ScreenOS versions 6.3.0r14 through 6.3.0r18 before 6.3.0r18-dnc1 Juniper Netscreen and ScreenOS Firewall products with ScreenOS version 6.3.0r19

Description The issue is related to the L2TP packet processing functionality, which allows remote attackers to cause a denial of service via a crafted L2TP packet. This is due to insufficient input validation in the ScreenOS operating system.

Recommendations For versions prior to 6.3.0r13-dnd1, update to version 6.3.0r13-dnd1 or later. For versions 6.3.0r14 through 6.3.0r18, update to version 6.3.0r18-dnc1 or later. For version 6.3.0r19, update to a version later than 6.3.0r19. As a temporary workaround, consider restricting the processing of L2TP packets until a patch is available.
