+ <description>
+ <p>
+ cstone and Richard Felker discovered a flaw in Screen's UTF-8 combining
+ character handling.
+ </p>
+ </description>
+ <impact type="high">
+ <p>
+ The vulnerability can be exploited by writing a special string of
+ characters to a Screen window. A remote attacker could cause a Denial
+ of Service or possibly execute arbitrary code with the privileges of
+ the user running Screen through a program being run inside a Screen
+ session, such as an IRC client or a mail client.
+ </p>
+ </impact>
+ <workaround>
+ <p>
+ There is no known workaround at this time.
+ </p>
+ </workaround>
+ <resolution>
+ <p>
+ All Screen users should upgrade to the latest version:
+ </p>
+ <code>
+ # emerge --sync
+ # emerge --ask --oneshot --verbose &quot;&gt;=app-misc/screen-4.0.3&quot;</code>
