DESCRIPTION:
A vulnerability has been reported in python-cjson, which can be
exploited by malicious people to cause a DoS (Denial of Service) and
potentially compromise an application using the module.

The vulnerability is caused due to a boundary error when encoding
certain wide unicode character sequences. This can be exploited to
cause a buffer overflow by e.g. tricking an application into encoding
specially crafted wide unicode strings.

The vulnerability is reported in version 1.0.5 on UCS4 builds. Other
versions may also be affected.

SOLUTION:
Use another module.
