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: www-client/chromium
Vulnerable: < 15.0.874.102
Unaffected: >= 15.0.874.102
Architectures: All supported architectures

Package: dev-lang/v8
Vulnerable: < 3.5.10.22
Unaffected: >= 3.5.10.22
Architectures: 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:
