tag_impact = "Successful exploitation may allow remote attackers to cause
a denial of service via a large integer argument.

Impact Level: Application";

tag_insight = "The flaw is due to an improper handling of argument sent to
the functions Int32Array, Float32Array, Float64Array, Uint32Array, Int16Array
or ArrayBuffer, which can be exploited to crash the Opera via a large
integer argument to these functions.";

tag_solution = "No solution or patch was made available for at least one year
since disclosure of this vulnerability. Likely none will be provided anymore.
General solution options are to upgrade to a newer release, disable respective
features, remove the product or replace the product by another one.";
