+ <description>
+ <p>
+ Tan Chew Keong reported about two vulnerabilities found in RAR:
+ </p>
+ <ul>
+ <li>A format string error exists when displaying a diagnostic
+ error message that informs the user of an invalid filename in an
+ UUE/XXE encoded file.</li>
+ <li>Some boundary errors in the processing
+ of malicious ACE archives can be exploited to cause a buffer
+ overflow.</li>
+ </ul>
+ </description>
+ <impact type="normal">
+ <p>
+ A remote attacker could exploit these vulnerabilities by enticing
+ a user to:
+ </p>
+ <ul><li>decode a specially crafted UUE/XXE file,
+ or</li>
+ <li>extract a malicious ACE archive containing a file with an
+ overly long filename.</li>
+ </ul>
+ <p>
+ When the user performs these
+ actions, the arbitrary code of the attacker's choice will be executed.
+ </p>
+ </impact>
+ <workaround>
+ <p>
+ There is no known workaround at this time.
+ </p>
+ </workaround>
+ <resolution>
+ <p>
+ All RAR users should upgrade to the latest version:
+ </p>
+ <code>
+ # emerge --sync
+ # emerge --ask --oneshot --verbose "&gt;=app-arch/rar-3.5.1"</code>
+ </resolution>
