<impact type="normal">
|
|
<p>
|
|
A remote attacker could entice a user to open a specially crafted
|
|
archive file resulting in a stack-based buffer overflow, possibly
|
|
crashing the application. It is disputed whether the execution of
|
|
arbitrary code is possible.

|
<workaround>
|
|
<p>
|
|
There is no known workaround at this time.
|
|
</p>
|
|
</workaround>
|
|
<resolution>
|
|
<p>
|
|
All GNU cpio users should upgrade to the latest version:
|
|
</p>
|
|
<code>
|
|
# emerge --sync
|
|
# emerge --ask --oneshot --verbose ">=app-arch/cpio-2.9-r1"</code>
