Juniper Networks NetScreen Release Notes
ScreenOS 5.0.0r9-FIPS P/N 093-1638-000, Rev. A Page 4 of 42
According to Trend Micro, the categories of viruses bypassed include HTML and
Javascript. However, the subset of the bypassed viruses can be described as the
following:
Javascript/Jscript/HTML embedded in HTML code (having HTTP content
type of text/HTML) AND is accessed through a script-enabled browser from a
remote web server (via HTTP).
For example, anti-virus scanning would NOT be bypassed for the following
scenarios:
1. Javascript/HTML malware which is stand-alone in a *.js file
2. Javascript/HTML malware propagating via email attachments
So the viruses bypassed would be all Javascript and HTML based viruses, but
accessed or contained with the above characteristics in HTTP traffic only.
2.3 New Features and Enhancements from ScreenOS 5.0.0r6
New Hidden Command - In response to the NISCC VULN 236929, a new
hidden command is implemented in this release. The command is set/unset flow
check tcp-rst-sequence. By default, the command is not set. This command
alters the device’s response to potentially spoofed TCP RST packets.
