Description

Two vulnerabilities have been reported in Google Chrome, which can be exploited by malicious people to disclose sensitive information or potentially compromise a user's system.

1) An error exists in WebKit when executing JavaScript code which sets a certain property of an HTML tag. This can be exploited to free child elements of the HTML tag and subsequently reference the freed memory when an HTML error is encountered.

Successful exploitation may allow execution of arbitrary code.

2) An error in WebKit when handling drag events can be exploited to disclose sensitive information when content is dragged over a malicious web page.

The vulnerabilities are reported in versions prior to 2.0.172.31.


Solution
Update to version 2.0.172.31.

Provided and/or discovered by
