than 21.0.1180.75 and is, therefore, affected by the following
vulnerabilities :

  - An unspecified use-after-free error exists in the PDF
    viewer. (CVE-2012-2862)

  - An unspecified out-of-bounds write error exists in the
    PDF viewer. (CVE-2012-2863)

Successful exploitation of either issue could lead to an application
crash or even allow arbitrary code execution, subject to the user's
privileges.");
