Hash: SHA1

The Pickle::Pickle function in base/pickle.cc in Google Chrome before
8.0.552.224 and Chrome OS before 8.0.552.343 on 64-bit Linux platforms
does not properly perform pointer arithmetic, which allows remote attackers
to bypass message deserialization validation, and cause a denial of service
or possibly have unspecified other impact, via invalid pickle data.

The attached patch comes from r68033 in the upstream repository and it's
issue 56449 (code review at http://codereview.chromium.org/4716006/).
