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

|
Tavis Ormandy of the Google Security team reported a heap-based buffer
|
|
overflow when compiling regular expression patterns containing
|
|
"Internal Option Settings" such as "<i>(?i)</i>".

<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.

All PCRE users should upgrade to the latest version:
|
|
</p>
|
|
<code>
|
|
# emerge --sync
|
|
# emerge --ask --oneshot --verbose ">=dev-libs/libpcre-7.7-r1"</code>

All GLib users should upgrade to the latest version:
|
|
</p>
|
|
<code>
|
|
# emerge --sync
|
|
# emerge --ask --oneshot --verbose ">=dev-libs/glib-2.16.3-r1"</code>
