The technical details are unknown and an exploit is not publicly available. The advisory points out:

On SRX Series devices, when any ALG (Application Layer Gateway) is enabled, a certain crafted packet 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. The status of ALGs can be obtained by executing the 'show security alg status' CLI command.

The vulnerability scanner Nessus provides a plugin with the ID 78421 , which helps to determine the existence of the flaw in a target environment. It is .

Upgrading to version 11.4R12-S4, 12.1X44-D40, 12.1X45-D30, 12.1X46-D25 or 12.1X47-D10 eliminates this vulnerability. A possible mitigation has been published immediately after the disclosure of the vulnerability. The advisory contains the following remark:

Two available workarounds exist for this issue: 1) Disable ALGs using the CLI command 'set security alg ____ disable' if ALGs are not required. 2) Enable flow-based processing for IPv6 traffic using the CLI command 'set security forwarding-options family inet6 mode flow-based' command (a device reboot is required).

The vulnerability is also documented in the databases at X-Force (96903), Tenable (78421), SecurityFocus (BID 70366†) and Vulnerability Center (SBV-46410†).
