Jean-Sebastien Guay-Leroux reported an integer underflow in
|
|
file_printf function.

<impact type="high">
|
|
<p>
|
|
A remote attacker could entice a user to run the "file" program on a
|
|
specially crafted file that would trigger a heap-based buffer overflow
|
|
possibly leading to the execution of arbitrary code with the rights of
|
|
the user running "file". Note that this vulnerability could be also
|
|
triggered through an automatic file scanner like amavisd-new.
|
|
</p>
|
|
</impact>
|
|
<workaround>
|
|
<p>
|
|
There is no known workaround at this time.
|
|
</p>
|
|
</workaround>
|
|
<resolution>
|
|
<p>
|
|
Since file is a system package, all Gentoo users should upgrade to the
|
|
latest version:
|
|
</p>
|
|
<code>
|
|
# emerge --sync
|
|
# emerge --ask --oneshot --verbose ">=sys-apps/file-4.20"</code>
|
