<impact type="normal">
|
|
<p>A context-dependent attacker could entice a user to open a specially
|
|
crafted file using an application linked against Pixman, possibly
|
|
resulting in execution of arbitrary code with the privileges of the
|
|
process, or a Denial of Service condition.

</p>

</impact>
|
|
<workaround>
|
|
<p>There is no known workaround at this time.</p>
|
|
</workaround>
|
|
<resolution>
|
|
<p>All Pixman users should upgrade to the latest version:</p>
|
|
|
|
<code>
|
|
# emerge --sync
|
|
# emerge --ask --oneshot --verbose ">=x11-libs/pixman-0.32.4"
|
|
</code>
|
|
|
|
<p>Packages which depend on this library may need to be recompiled. Tools
|
|
such as revdep-rebuild may assist in identifying these packages.
