<impact type="normal">
|
|
<p>A remote attacker could entice a user to process a specially crafted
|
|
file in an application linked against libxslt, possibly resulting in a
|
|
Denial of Service condition.
|
|
</p>
|
|
</impact>
|
|
<workaround>
|
|
<p>There is no known workaround at this time.</p>
|
|
</workaround>
|
|
<resolution>
|
|
<p>All libxslt users should upgrade to the latest version:</p>
|
|
|
|
<code>
|
|
# emerge --sync
|
|
# emerge --ask --oneshot --verbose ">=dev-libs/libxslt-1.1.28"
|
|
</code>
|
|
|
|
<p>Packages which depend on this library may need to be recompiled. Tools
|
|
such as revdep-rebuild may assist in identifying some of these packages.
