|
<p>
|
|
Jeff Phillips discovered that libpng does not properly parse 1-bit
|
|
interlaced images with width values that are not divisible by 8, which
|
|
causes libpng to include uninitialized bits in certain rows of a PNG
|
|
file.
|
|
</p>

|

|
|
<impact type="low">
|
|
<p>
|
|
A remote attacker might entice a user to open a specially crafted PNG
|
|
file, possibly resulting in the disclosure of sensitive memory
|
|
portions.
|
|
</p>
|
|
</impact>
|
|
<workaround>
|
|
<p>
|
|
There is no known workaround at this time.
|
|
</p>
|
|
</workaround>
|
|
<resolution>
|
|
<p>
|
|
All libpng users should upgrade to the latest version:
|
|
</p>
|
|
<code>
|
|
# emerge --sync
|
|
# emerge --ask --oneshot --verbose ">=media-libs/libpng-1.2.37"</code>
