* 3DS browser, 2^32 characters long string: this is similar to the vulnerability fixed [http://git.chromium.org/gitweb/?p=external/Webkit.git;a=commitdiff;h=ec471f16fbd1f879cb631f9b022fd16acd75f4d4 here], concat-large-strings-crash2.html triggers a crash which is about the same as the one triggered by a 2^32 string. Most of the time this vulnerability will cause a memory page permissions fault, since the WebKit code attempts to copy the string text data to the output buffer located in read-only [[CRO0|CRO]] heap memory. The only difference between a crash triggered by a 2^32 string and the concat-large-strings-crash2.html crash is at the former copies the string data using the original string length(like 1 text character for "x", 4 for "xxxx") while the latter attempts to copy >12MB. In some ''very'' rare cases a thread separate from the string data-copy thread will crash, this might be exploitable. However, this is mostly useless since it rarely crashes this way.
