zlib is a widely used free and patent unencumbered data
|
|
compression library.

<description>
|
|
<p>
|
|
zlib improperly handles invalid data streams which could lead to a
|
|
buffer overflow.
|
|
</p>
|

|
|
<impact type="high">
|
|
<p>
|
|
By creating a specially crafted compressed data stream, attackers
|
|
can overwrite data structures for applications that use zlib, resulting
|
|
in arbitrary code execution or a Denial of Service.
|
|
</p>
|
|
</impact>
|
|
<workaround>
|
|
<p>
|
|
There is no known workaround at this time.
|
|
</p>
|
|
</workaround>
|
|
<resolution>
|
|
<p>
|
|
All zlib users should upgrade to the latest version:
|
|
</p>
|
|
<code>
|
|
# emerge --sync
|
|
# emerge --ask --oneshot --verbose ">=sys-libs/zlib-1.2.3"</code>
