<p>
PCRE is a Perl-compatible regular expression library. GLib includes a
copy of PCRE.
</p>
</background>
<description>
<p>
PCRE contains a buffer overflow vulnerability when processing a
character class containing a very large number of characters with
codepoints greater than 255.
</p>
</description>
<impact type="high">
<p>
A remote attacker could exploit this vulnerability by sending a
specially crafted regular expression to an application making use of
the PCRE library, which could possibly lead to the execution of
arbitrary code or a Denial of Service.
</p>
</impact>
<workaround>
<p>
There is no known workaround at this time.
</p>
</workaround>
<resolution>
<p>
All PCRE users should upgrade to the latest version:
</p>
<code>
# emerge --sync
# emerge --ask --oneshot --verbose &quot;&gt;=dev-libs/libpcre-7.6-r1&quot;</code>
<p>
All GLib users should upgrade to the latest version:
</p>
<code>
# emerge --sync
# emerge --ask --oneshot --verbose &quot;&gt;=dev-libs/glib-2.14.6&quot;</code>
