The vulnerability is caused due to a boundary error within the transparent cookie encryption. If cookie encryption is enabled (disabled by default), this can be exploited to cause a stack-based buffer overflow by e.g. sending specially crafted input to an affected script. Successful exploitation may allow execution of arbitrary code, but e.g. requires an application to pass untrusted input to the "header()" function when setting a cookie and a weak Suhosin configuration (e.g. multiheader option enabled and NULL-byte protection disabled, both not default). The vulnerability is reported in versions prior to 0.9.33. SOLUTION: Update to version 0.9.33. PROVIDED AND/OR DISCOVERED BY: Reported by the vendor.
