Debian Security Advisory DSA-1775-1 security@debian.org

- ------------------------------------------------------------------------

Package : php-json-ext
Vulnerability : denial of service
Problem type : remote
Debian-specific: no
CVE ID : CVE-2009-1271


It was discovered that php-json-ext, a JSON serialiser for PHP, is
prone to a denial of service attack, when receiving a malformed string
via the json_decode function.


For the oldstable distribution (etch), this problem has been fixed in
version 1.2.1-3.2+etch1.

The stable distribution (lenny) does not contain a separate php-json-ext
package, but includes it in the php5 packages, which will be fixed soon.

The testing distribution (squeeze) and the unstable distribution (sid)
do not contain a separate php-json-ext package, but include it in the
php5 packages.

We recommend that you upgrade your php-json-ext packages.


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

wget url
will fetch the file for you
dpkg -i file.deb
will install the referenced file.

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

apt-get update
will update the internal database
apt-get upgrade
will install corrected packages

You may use an automated update by adding the resources from the
footer to the proper configuration.
