|
|
Tavis Ormandy of the Gentoo Linux Security Audit Team discovered a
|
|
buffer overflow in zlib. A bounds checking operation failed to take
|
|
invalid data into account, allowing a specifically malformed deflate
|
|
data stream to overrun a buffer.
|
|

<impact type="high">
|
|
<p>
|
|
An attacker could construct a malformed data stream, embedding it
|
|
within network communication or an application file format, potentially
|
|
resulting in the execution of arbitrary code when decoded by the
|
|
application using the zlib library.

</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-1.2.2-r1"</code>
