<title>rssh: Format string vulnerability</title>
|
||
|
|
<synopsis>
|
||
|
|
rssh is vulnerable to a format string vulnerability that allows arbitrary
|
||
|
|
execution of code with the rights of the connected user, thereby bypassing
|
||
|
|
rssh restrictions.

rssh is a restricted shell, allowing only a few commands like scp or
|
||
|
|
sftp. It is often used as a complement to OpenSSH to provide limited
|
||
|
|
access to users.

Florian Schilhabel from the Gentoo Linux Security Audit Team found a
|
||
|
|
format string vulnerability in rssh syslogging of failed commands.

<impact type="high">
|
||
|
|
<p>
|
||
|
|
Using a malicious command, it may be possible for a remote
|
||
|
|
authenticated user to execute arbitrary code on the target machine with
|
||
|
|
user rights, effectively bypassing any restriction of rssh.
|
||
|
|
</p>
|
||
|
|
</impact>
|
||
|
|
<workaround>
|
||
|
|
<p>
|
||
|
|
There is no known workaround at this time.
|
||
|

|
||
|

</workaround>
|
||
|
|
<resolution>
|
||
|
|
<p>
|
||
|
|
All rssh users should upgrade to the latest version:
|
||
|
|
</p>
|
||
|
|
<code>
|
||
|
|
# emerge --sync
|
||
|
|
# emerge --ask --oneshot --verbose ">=app-shells/rssh-2.2.2"</code>
