Debian DSA-1775-1 : php-json-ext - denial of service

medium Nessus Plugin ID 36189

Synopsis

The remote Debian host is missing a security-related update.

Description

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.

Solution

Upgrade the php-json-ext packages.

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.
