Package : python-cjson
Vulnerability : buffer overflow
Problem type : remote
Debian-specific: no
CVE Id : CVE-2010-1666
Debian Bug : 587700


Matt Giuca discovered a buffer overflow in python-cjson, a fast JSON
encoder/decoder for Python.
This allows a remote attacker to cause a denial of service (application crash)
through a specially-crafted Python script.


For the stable distribution (lenny), this problem has been fixed in
version 1.0.5-1+lenny1

For the testing (squeeze) and the unstable (sid) distribution, this problem
has been fixed in version 1.0.5-3

We recommend that you upgrade your python-cjson package.

Upgrade instructions
- --------------------

If you are using the apt-get package manager, use the line for
sources.list as given below:
