Earlier today, we were notified of a vulnerability in an operating system named ScreenOS used to manage firewalls sold by Juniper Networks.  Yesterday, Juniper Networks announced that ScreenOS contains unauthorized code that surreptitiously decrypts traffic sent through virtual private network (VPN) connections [1].

The vulnerability has been designated as CVE-2015-7755.  Juniper's Security Incident Response Team (SIRT) strongly recommends users upgrade to a fixed release of ScreenOS to resolve these critical vulnerabilities [2].

Juniper firewalls using ScreenOS 6.2.0r15 through 6.2.0r18 and 6.3.0r12 through 6.3.0r20 are affected and should be patched immediately.

A notification has come out through the US CERT [3].  Some other sources have also issued reports about it [4, 5].

See the CVE link above or references below for more information.
