Vulnerabilities
###############

This page collects all of the vulnerabilities that are discovered and
fixed in each release.  It will also often have more details than is
available in the releases.  Some vulnerabilities are deemed to be
sensitive, and will not be publically discussed until there is
sufficient time to fix them.  Because the release notes are locked to
a version, the information here can be updated after the embargo is
lifted.

CVE-2017
========

CVE-2017-14199
--------------

Buffer overflow in :code:`getaddrinfo()`.

  <https://github.com/zephyrproject-rtos/zephyr/pull/6158>`_

CVE-2017-14201
--------------

The shell DNS command can cause unpredictable results due to misuse of
stack variables.

Use After Free vulnerability in the Zephyr shell allows a serial or
telnet connected user to cause denial of service, and possibly remote
code execution.

This has been fixed in release v1.14.0.

CVE-2017-14202
--------------

The shell implementation does not protect against buffer overruns
resulting in unpredicable behavior.

Improper Restriction of Operations within the Bounds of a Memory
Buffer vulnerability in the shell component of Zephyr allows a serial
or telnet connected user to cause a crash, possibly with arbitrary
code execution.

This has been fixed in release v1.14.0.

CVE-2019
========

CVE-2019-9506
-------------

The Bluetooth BR/EDR specification up to and including version 5.1
permits sufficiently low encryption key length and does not prevent an
attacker from influencing the key length negotiation. This allows
practical brute-force attacks (aka "KNOB") that can decrypt traffic
and inject arbitrary ciphertext without the victim noticing.

CVE-2020-10059
--------------

UpdateHub Module Explicitly Disables TLS Verification

The UpdateHub module disables DTLS peer checking, which allows for a
man in the middle attack. This is mitigated by firmware images
requiring valid signatures. However, there is no benefit to using DTLS
without the peer checking.

See NCC-ZEP-018

CVE-2020-10060
--------------

UpdateHub Might Dereference An Uninitialized Pointer

In updatehub_probe, right after JSON parsing is complete, objects\[1]
is accessed from the output structure in two different places. If the
JSON contained less than two elements, this access would reference
unitialized stack memory. This could result in a crash, denial of
service, or possibly an information leak.

Recommend disabling updatehub until such a time as a fix can be made
available.
