Mono provides the necessary software to develop and run .NET client and
|
|
server applications.

<description>
|
|
<p>
|
|
Sebastian Krahmer of the SuSE Security Team discovered that the
|
|
System.CodeDom.Compiler classes of Mono create temporary files with
|
|
insecure permissions.
|
|
</p>
|
|
</description>
|
|
<impact type="normal">
|
|
<p>
|
|
A local attacker could create links in the temporary file directory,
|
|
pointing to a valid file somewhere on the filesystem. When an affected
|
|
class is called, this could result in the file being overwritten with
|
|
the rights of the user running the script.
|
|
</p>
|
|
</impact>
|
|
<workaround>
|
|
<p>
|
|
There is no known workaround at this time.
|
|
</p>
|
|
</workaround>
|
|
<resolution>
|
|
<p>
|
|
All Mono users should upgrade to the latest version:
|
|
</p>
|
|
<code>
|
|
# emerge --sync
|
|
# emerge --ask --oneshot --verbose ">=dev-lang/mono-1.1.13.8.1"</code>
