## Description

Use-after-free vulnerability in Google Chrome 17.0.963.66 and earlier
allows remote attackers to bypass the DEP and ASLR protection mechanisms,
and execute arbitrary code, via unspecified vectors, as demonstrated by
VUPEN during a Pwn2Own competition at CanSecWest 2012. NOTE: the primary
affected product may be clarified later; it was not identified by the
researcher, who reportedly stated "it really doesn't matter if it's
third-party code."

### [jdstrand](https://launchpad.net/~jdstrand)

VUPEN won't release the exploit to Google to fix it, and access to
the exploit is behind a paywall, so there is nothing to do. Marking deferred
for now. Will re-open if new information is available.
