Google Releases Security Update for Chrome

Chrome version 11.0.696.71, which fixes four vulnerabilities in the Google browser, was released today.

Two of the vulnerabilities, deemed "critical," relate to a memory corruption error in the GPU command buffer and an out-of-bounds write issue in blob handling. They were discovered by Google's internal security engineers.

A third vulnerability, labeled "high," related to a bug in code that handles dynamic memory. This "stale pointer" vulnerability could lead to data transfer when aliases are created for allocated memory. Martin Barbella, a researcher not associated with Google, discovered the flaw and was awarded $1,000 as part of the company's Chromium security program.

The final vulnerability fix, categorized as "low," patches an issue that can cause a bug to bypass the popup blocker.

While the holes have been outlined by Google, details of each problem and patch are being withheld until a majority of Chrome users have updated. Today's patch marks the second security update this month to Chrome's "stable" build.

The release of today's updated browser does not fix a zero-day sandbox vulnerability that a French security research team, Vupen, had announced it had discovered earlier in the month. Aside from a handful of Google engineers taking to Twitter to blame the hole on Adobe's Flash software, the company has yet to publicly comment on the issue, besides a statement saying it was unable to investigate the claim due to the fact that Vupen would not share the information outside its paying clients.  

Google Chrome, version 11.0.696.71 can be downloaded here.
