Technical Description

Two vulnerabilities have been identified in Google Chrome, which could be exploited by remote attackers to compromise a vulnerable system.

The first issue is caused by a heap overflow error when evaluating a specially crafted regular expression in Javascript, which could be exploited to crash an affected browser and execute arbitrary code in the sandbox.

The second vulnerability is caused by an error when allocate memory buffers for a renderer (tab) process, which could allow a compromised process (e.g. via the first issue) to cause the browser process (and all tabs) to crash or execute arbitrary code with the privileges of the logged on user, bypassing the sandbox.
