CVE-2017-10610
On SRX Series devices, a crafted ICMP packet embedded within a NAT64 IPv6 to IPv4 tunnel may cause the flowd process to crash.
Does this matter?
Lower severity and a low EPSS score (1.05%). Track it; it rarely justifies an emergency change on its own.
Description
On SRX Series devices, a crafted ICMP packet embedded within a NAT64 IPv6 to IPv4 tunnel may cause the flowd process to crash. Repeated crashes of the flowd process constitutes an extended denial of service condition for the SRX Series device. This issue only occurs if NAT64 is configured.
