2014-07 Security Bulletin: Junos: Denial of Service vulnerability in flowd
related to SIP ALG (CVE-2014-3815)

Security Advisories ID:		JSA10633
Last Updated:		    	09 Jul 2014
Version:			1.0

Product Affected:
This issue affects SRX Series devices running Junos OS 12.1X46 prior
to 12.1X46-D20

Problem:
On SRX Series devices, when SIP ALG is enabled, a certain crafted SIP
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. SIP ALG is enabled by default on SRX Series devices except
for SRX-HE devices. SRX-HE devices have SIP ALG disabled by default. The
status of ALGs can be obtained by executing the 'show security alg status'
CLI command.

Juniper SIRT is not aware of any malicious exploitation of this
vulnerability.

No other Juniper Networks products or platforms are affected by this issue.

This issue has been assigned CVE-2014-3815.

Solution:
The following software releases have been updated to resolve this specific
issue: Junos OS 12.1X46-D20, 12.1X47-D10, and all subsequent releases
(i.e. all releases built after 12.1X47-D10).

This issue is being tracked as PR 964817 and is visible on the Customer
Support website.

KB16765 - "In which releases are vulnerabilities fixed?" describes which
release vulnerabilities are fixed as per our End of Engineering and End
of Life support policies.

Workaround:
Two available workarounds exist for this issue:

    Disable SIP ALG using the CLI command 'set security alg sip disable'
    if SIP ALG is not required
    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)

Implementation:
How to obtain fixed software:

Security vulnerabilities in Junos are fixed in the next available
Maintenance Release of each supported Junos version. In some cases,
a Maintenance Release is not planned to be available in an appropriate
time-frame. For these cases, Service Releases are made available in order
to be more timely. Security Advisory and Security Notices will indicate
which Maintenance and Service Releases contain fixes for the issues
described. Upon request to JTAC, customers will be provided download
instructions for a Service Release. Although Juniper does not provide
formal Release Note documentation for a Service Release, a list of "PRs
fixed" can be provided on request.
