Am I affected?
Debian, Ubuntu or Red Hat sometimes backport a fix without changing the upstream version number: such a version reads « to verify », never « affected ».With a domain, we read the version its public headers and pages expose. A distribution build can carry the fix under an older number.
Description
The Array.prototype.concat implementation in builtins.cc in Google V8, as used in Google Chrome before 49.0.2623.108, does not properly consider element data types, which allows remote attackers to cause a denial of service (out-of-bounds read) or possibly have unspecified other impact via crafted JavaScript code.
