+ <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.

+ <background>
+ <p>
+ 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.

+ <description>
+ <p>
+ Florian Schilhabel from the Gentoo Linux Security Audit Team found a
+ format string vulnerability in rssh syslogging of failed commands.
+ </p>
+ </description>
+ <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.
+ </p>
+ </workaround>
+ <resolution>
+ <p>
+ All rssh users should upgrade to the latest version:
+ </p>
+ <code>
+ # emerge --sync
+ # emerge --ask --oneshot --verbose &quot;&gt;=app-shells/rssh-2.2.2&quot;</code>
+ </resolution>
