CVS (Concurrent Versions System) is an open-source network-transparent
|
|
version control system. It contains both a client utility and a server.

|
|
Stefan Esser discovered a heap overflow in the CVS server, which can be
|
|
triggered by sending malicious "Entry" lines and manipulating the flags
|
|
related to that Entry. This vulnerability was proven to be exploitable.

<impact type="high">
|
|
<p>
|
|
A remote attacker can execute arbitrary code on the CVS server, with the
|
|
rights of the CVS server. By default, Gentoo uses the "cvs" user to run the
|
|
CVS server. In particular, this flaw allows a complete compromise of CVS
|
|
source repositories. If you're not running a server, then you are not
|
|
vulnerable.
|
|
</p>
|
|
</impact>
|
|
<workaround>
|
|
<p>
|
|
There is no known workaround at this time. All users are advised to upgrade
|
|
to the latest available version of CVS.
|
|
</p>
|
|
</workaround>
|
|
<resolution>
|
|
<p>
|
|
All users running a CVS server should upgrade to the latest stable version:
|
|
</p>

<code>
|
|
# emerge sync
|
|
|
|
# emerge -pv ">=dev-util/cvs-1.11.16"
|
|
# emerge ">=dev-util/cvs-1.11.16"</code>
