Synopsis

Multiple vulnerabilities have been reported in Chromium and V8, some of which may allow execution of arbitrary code and local root privilege escalation.

Background

Chromium is an open-source web browser project. V8 is Google's open source JavaScript engine.

Affected packages

Package	Vulnerable	Unaffected	Architecture(s)
www-client/chromium	< 15.0.874.102	>= 15.0.874.102	All supported architectures
dev-lang/v8	< 3.5.10.22	>= 3.5.10.22	All supported architectures

Description

Multiple vulnerabilities have been discovered in Chromium and V8. Please review the CVE identifiers and release notes referenced below for details.

Impact

A local attacker could gain root privileges (CVE-2011-1444, fixed in chromium-11.0.696.57).

A context-dependent attacker could entice a user to open a specially crafted web site or JavaScript program using Chromium or V8, possibly resulting in the execution of arbitrary code with the privileges of the process, or a Denial of Service condition. The attacker also could obtain cookies and other sensitive information, conduct man-in-the-middle attacks, perform address bar spoofing, bypass the same origin policy, perform Cross-Site Scripting attacks, or bypass pop-up blocks.

Workaround

There is no known workaround at this time.

Resolution

All Chromium users should upgrade to the latest version:

      # emerge --sync
      # emerge --ask --oneshot --verbose
      ">=www-client/chromium-15.0.874.102"

All V8 users should upgrade to the latest version:


      # emerge --sync
      # emerge --ask --oneshot --verbose ">=dev-lang/v8-3.5.10.22"
