A team audit of the CVS source code performed by Stefan Esser and Sebastian
|
|
Krahmer resulted in the discovery of several remotely exploitable
|
|
vulnerabilities including:
|
|
</p>
|
|
<ul>
|
|
<li>no-null-termination of "Entry" lines</li>
|
|
<li>error_prog_name "double-free()"</li>
|
|
<li>Argument integer overflow</li>
|
|
<li>serve_notify() out of bounds writes</li>
|
|
</ul>

<impact type="high">
|
|
<p>
|
|
An attacker could use these vulnerabilities to cause a Denial of Service or
|
|
execute arbitrary code with the permissions of the user running cvs.
|
|
</p>
|
|
</impact>
|
|
<workaround>
|
|
