OVERVIEW

        Google have released a new version of Chrome, correcting several
        security vulnerabilities.


IMPACT

        The vendor has provided the following information regarding these
        vulnerabilities:
        
        A flaw in the V8 Javascript engine might allow specially-crafted 
        Javascript on a web page to read unauthorized memory, bypassing 
        security checks. It is possible that this could lead to disclosing 
        unauthorized data to an attacker or allow an attacker to run 
        arbitrary code. [1]
        
        Pages using XML can cause a Google Chrome tab process to crash. A 
        malicious XML payload may be able to trigger a use-after-free 
        condition. Other tabs are unaffected. [1]


MITIGATION

        Google has made version 2.0.172.37 available for download from their 
        website. [2]
