Name of the Vulnerable Software and Affected Versions Google Chrome versions prior to 49.0.2623.75 Opera versions prior to 49.0.2623.75

Description The issue arises from inadequate determination of when anonymous block wrappers may exist in the WebKit/Source/core/layout/LayoutBlock.cpp function of the Blink engine, as used in Google Chrome and Opera. This allows remote attackers to cause a denial of service, resulting in an assertion failure, or possibly have other unspecified impacts through crafted JavaScript code.

Recommendations For Google Chrome versions prior to 49.0.2623.75, update to version 49.0.2623.75 or later. For Opera versions prior to 49.0.2623.75, update to a version that incorporates the fix for this issue, although the specific version is not specified in the provided data. At the moment, there is no information about a newer version that contains a fix for this vulnerability in Opera.
