|
libpcre is a library providing functions for Perl-compatible
|
|
regular expressions.

|
<description>
|
|
<p>
|
|
libpcre fails to check certain quantifier values in regular
|
|
expressions for sane values.
|
|
</p>
|
|
</description>
|
|
<impact type="high">
|
|
<p>
|
|
An attacker could possibly exploit this vulnerability to execute
|
|
arbitrary code by sending specially crafted regular expressions to
|
|
applications making use of the libpcre library.
|
|
</p>
|
|
</impact>
|
|
<workaround>
|
|
<p>
|
|
There is no known workaround at this time.
|
|
</p>
|
|
</workaround>
|
|
<resolution>
|
|
<p>
|
|
All libpcre users should upgrade to the latest version:
|
|
</p>
|
|
<code>
|
|
# emerge --sync
|
|
# emerge --ask --oneshot --verbose ">=dev-libs/libpcre-6.3"</code>
