The host is installed with Adobe Flash Player before 9.0.277.0 or 10.x before 10.1.53.64 and is prone to denial of service vulnerability. A flaw is present in an application, which fails to handle the SWF files. Successful exploitation could allow attackers to cause a denial of service (NULL pointer dereference and browser crash) by returning a different response when an HTTP request is sent a second time, as demonstrated by two responses that provide SWF files with different SWF version numbers.
