|
Carsten Lohrke of Gentoo Linux reported that Pngcrush contains a
|
|
vulnerable version of zlib (GLSA 200507-19).

<impact type="normal">
|
|
<p>
|
|
By creating a specially crafted data stream, attackers can
|
|
overwrite data structures for applications that use Pngcrush, resulting
|
|
in a Denial of Service and potentially arbitrary code execution.
|
|
</p>
|
|
</impact>
|
|
<workaround>
|
|
<p>
|
|
There is no known workaround at this time.
|
|
</p>
|
|
</workaround>
|
|
<resolution>
|
|
<p>
|
|
All Pngcrush users should upgrade to the latest version:
|
|
</p>
|
|
<code>
|
|
# emerge --sync
|
|
# emerge --ask --oneshot --verbose ">=media-gfx/pngcrush-1.6.2"</code>
