|
|
Tavis Ormandy of the Google Security Team discovered a static buffer
|
|
underflow in ncompress.
|

</p>
|
|
</description>
|
|
<impact type="normal">
|
|
<p>
|
|
An attacker could create a specially crafted LZW archive, that when
|
|
decompressed by a user or automated system would result in the
|
|
execution of arbitrary code with the permissions of the user invoking
|
|
the utility.
|
|
</p>
|

</impact>
|
|
<workaround>
|
|
<p>
|
|
There is no known workaround at this time.
|
|
</p>
|
|
</workaround>
|
|
<resolution>
|
|
<p>
|
|
All ncompress users should upgrade to the latest version:
|
|
</p>
|
|
<code>
|
|
# emerge --sync
|
|
# emerge --ask --oneshot --verbose ">=app-arch/ncompress-4.2.4.1"</code>
