|
|
Andrea Barisani of Gentoo Linux discovered xzgv and zgv allocate
|
|
insufficient memory when rendering images with more than 3 output
|
|
components, such as images using the YCCK or CMYK colour space. When
|
|
xzgv or zgv attempt to render the image, data from the image overruns a
|
|
heap allocated buffer.
|
|
</p>

|
|
<impact type="normal">
|
|
<p>
|
|
An attacker may be able to construct a malicious image that executes
|
|
arbitrary code with the permissions of the xzgv or zgv user when
|
|
attempting to render the image.
|
|

<workaround>
|

<p>
|
|
There is no known workaround at this time.

All xzgv users should upgrade to the latest version:
|
|
</p>
|
|
<code>
|
|
# emerge --sync
|
|
# emerge --ask --oneshot --verbose ">=media-gfx/xzgv-0.8-r2"</code>
|
|
<p>
|
|
All zgv users should also upgrade to the latest version:
|
|
</p>
|
|
<code>
|
|
# emerge --sync
|
|
# emerge --ask --oneshot --verbose ">=media-gfx/zgv-5.9"</code>
