    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.
