|
<p>GNOME Shell provides core user interface functions for the GNOME desktop, like switching to windows and launching applications.
|
||
|
|
||
|
gettext contains the GNU locale utilities.
|
||
|
|
||
|
libcroco is a standalone CSS2 parsing and manipulation library.</p>
|
||
|
</background>
|
||
|
<description>
|
||
|
<p>The cr_parser_parse_any_core function in libcroco's cr-parser.c does not limit recursion, leading to a denial of service via a stack overflow when trying to parse crafted CSS.
|
||
|
|
||
|
Gnome Shell and gettext bundle libcroco in their own sources and thus are potentially vulnerable as well.</p>
|
||
|
</description>
|
||
|
<impact type="normal">
|
||
|
<p>An attacker with control over the input to the library can cause a denial of service.</p>
|
||
|
</impact>
|
||
|
<workaround>
|
||
|
<p>There is no known workaround at this time.</p>

</workaround>

<p>All gettext users should upgrade to the latest version:</p>
