PCRE is a Perl-compatible regular expression library. GLib includes a
|
|
copy of PCRE.

<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.
|

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

All PCRE users should upgrade to the latest version:
|
|
</p>
|
|
<code>
|
|
# emerge --sync
|
|
# emerge --ask --oneshot --verbose ">=dev-libs/libpcre-7.6-r1"</code>

|
</p>
|
|
<code>
|
|
# emerge --sync
|
|
# emerge --ask --oneshot --verbose ">=dev-libs/glib-2.14.6"</code>
