Description

The vulnerability allows a remote non-authenticated attacker to execute arbitrary code.

Google Chrome before 8.0.552.237 and Chrome OS before 8.0.552.344 do not properly handle Cascading Style Sheets (CSS) token sequences in conjunction with cursors, which allows remote attackers to cause a denial of service or possibly have unspecified other impact via unknown vectors that lead to a "stale pointer."

Mitigation
Install update from vendor's website.
