DoS when translating from IPv6 to IPv4.
Unauthenticated attackers can cause a DoS condition by repeatedly exploiting this vulnerability.
New builds of Junos OS software are available from Juniper. As a workaround disable NAT translation from IPv6 to IPv4 if not required.
A denial of service (DoS) issue has been discovered in Juniper SRX Series products that can be exploited by remote unauthenticated attackers. This issue takes place when a certain malformed packet is translated from IPv6 to IPv4. When this malformed packet is sent to a vulnerable SRX Series device, the flowd process may crash.
Junos OS 11.4, 12.1, 12.1X44, 12.1X45 and 12.1X46.
Check the OS build.
