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 ">=app-arch/rar-3.5.1"</code>
|
|
</resolution>
