gsol17238: Node.js vulnerability CVE-2015-5380 Security Advisory
Original Publication Date: 09/08/2015
Description
The Utf8DecoderBase::WriteUtf16Slow function in unicode-decoder.cc in
Google V8, as used in Node.js before 0.12.6, io.js before 1.8.3 and 2.x
before 2.3.3, and other products, does not verify that there is memory
available for a UTF-16 surrogate pair, which allows remote attackers to
cause a denial of service (memory corruption) or possibly have unspecified
other impact via a crafted byte sequence. (CVE-2015-5380)
Impact
For the f5-rest-node package on both the BIG-IP and BIG-IQ systems: A
locally authenticated attacker with access to the command line may be
able to cause a partial denial-of-service (DoS) to the system through
exploitation of this issue.
For the BIG-IQ UI node package: A remote attacker may be able to cause a
denial of service (DoS) to the system through exploitation of this issue.
Status
F5 Product Development has assigned ID 534090 and ID 534358 (BIG-IP),
ID 537658 (BIG-IQ), and LRS-59013 (LineRate) to this vulnerability, and
has evaluated the currently supported releases for potential vulnerability.

Recommended Action
If the previous table lists a version in the Versions known to be not
vulnerable column, you can eliminate this vulnerability by upgrading to
the listed version. If the listed version is older than the version you
are currently running, or if the table does not list any version in the
column, then no upgrade candidate currently exists.
F5 responds to vulnerabilities in accordance with the Severity values
published in the previous table. The Severity values and other security
vulnerability parameters are defined in SOL4602: Overview of the F5 security
vulnerability response policy.
There is no mitigation for this vulnerability. However, F5 recommends that
you permit management access to affected F5 products only over a secure
network, and limit shell access to trusted users. For more information about
securing access to BIG-IP systems, refer to SOL13309: Restricting access
to the Configuration utility by source IP address (11.x) and SOL13092:
Overview of securing access to the BIG-IP system.
