Referencer i sikkerhedsdatabaser:

I Mitres CVE-ordbog: CVE-2009-1271.

Yderligere oplysninger:

Man opdagede at php-json-ext, en JSON-serialiser til PHP, var sårbar over for et lammelsesangreb (deniel of service), når der blev modtaget en misdannet streng gennem funktionen json_decode.

I den gamle stabile distribution (etch), er dette problem rettet i version 1.2.1-3.2+etch1.

Den stabile distribution (lenny) indeholder ikke en separat php-json-ext-pakke, men det er indeholdt i php5-pakkerne, der snart vil blive rettet.

Distribution testing (squeeze) og den ustabile distribution (sid) indeholder ikke en separat php-json-ext-pakke, men det er indeholdt i php5-pakkerne.

Vi anbefaler at du opgraderer dine php-json-ext-pakker.

Rettet i:

Debian GNU/Linux 4.0 (etch)
