Google started the new year by fixing a serious vulnerability in Gmail.
This was quite an interesting case and once again (as everything relating to web apps seems to be nowdays) it was an XSS flaw that allowed malicious attackers to steal your contact list, leading to some pretty bad information leakage.
Google has fixed a vulnerability in its popular GMail web mail service that creates a means for hackers to steal users’ contact lists.
There was a previous very similar flaw on Google which effected computers with multiple Gmail users.
As a result users logged into GMail, or other Google services sharing the same login, are liable to hand over their contact list to spammers or other miscreants providing they are tricked into visiting a maliciously constructed website. Exploitation would have been as simple as fooling users into visiting a hostile website through spam messages sent to users’ email accounts.
I do like Google though, they tend to fix things pretty fast!
