<description>

<p>
|
|
Javier Fernandez-Sanguino has discovered that xferfaxstats cron script
|
|
supplied by Hylafax insecurely creates temporary files with predictable
|
|
filenames.
|
|

<impact type="normal">
|
|
<p>
|
|
A local attacker could create symbolic links in the temporary file
|
|
directory, pointing to a valid file somewhere on the filesystem. When
|
|
the xferfaxstats script of Hylafax is executed, this would result in
|
|
the file being overwritten with the rights of the user running the
|
|
script, which typically is the root user.
|
|
</p>
|
|
</impact>
|
|
<workaround>
|
|
<p>
|
|
There is no known workaround at this time.
|
|
</p>
|
|
</workaround>
|
|
<resolution>
|
|
<p>
|
|
All Hylafax users should upgrade to the latest version:
|
|
</p>
|
|
<code>
|
|
# emerge --sync
|
|
# emerge --ask --oneshot --verbose net-misc/hylafax</code>
