<background>
<p>
scponly is a shell for restricting user access to file transfer only
using sftp and scp.

<description>
<p>
Joachim Breitner reported that Subversion and rsync support invokes
subcommands in an insecure manner (CVE-2007-6350). It has also been
discovered that scponly does not filter the -o and -F options to the
scp executable (CVE-2007-6415).
</p>
</description>
<impact type="normal">
<p>
A local attacker could exploit these vulnerabilities to elevate
privileges and execute arbitrary commands on the vulnerable host.
</p>
</impact>
<workaround>
<p>
There is no known workaround at this time.
</p>
</workaround>
<resolution>
<p>
All scponly users should upgrade to the latest version:
</p>
<code>
# emerge --sync
# emerge --ask --oneshot --verbose &quot;&gt;=net-misc/scponly-4.8&quot;</code>
<p>
Due to the design of scponly's Subversion support, security
restrictions can still be circumvented. Please read carefully the
SECURITY file included in the package.
