Affected Packages

------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 www-client/chromium < 15.0.874.102 >= 15.0.874.102 2 dev-lang/v8 < 3.5.10.22 >= 3.5.10.22 ------------------------------------------------------------------- 2 affected packages -------------------------------------------------------------------

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.
