+  <synopsis>
+    PCRE is vulnerable to multiple buffer overflow and memory corruption
+    vulnerabilities, possibly leading to the execution of arbitrary code.

+    PCRE is a library providing functions for Perl-compatible regular

+    Tavis Ormandy (Google Security) discovered multiple vulnerabilities in
+    PCRE. He reported an error when processing "\Q\E" sequences with
+    unmatched "\E" codes that can lead to the compiled bytecode being
+    corrupted (CVE-2007-1659). PCRE does not properly calculate sizes for
+    unspecified "multiple forms of character class", which triggers a
+    buffer overflow (CVE-2007-1660). Further improper calculations of
+    memory boundaries were reported when matching certain input bytes
+    against regex patterns in non UTF-8 mode (CVE-2007-1661) and when
+    searching for unmatched brackets or parentheses (CVE-2007-1662).
+    Multiple integer overflows when processing escape sequences may lead to
+    invalid memory read operations or potentially cause heap-based buffer
+    overflows (CVE-2007-4766). PCRE does not properly handle "\P" and
+    "\P{x}" sequences which can lead to heap-based buffer overflows or
+    trigger the execution of infinite loops (CVE-2007-4767), PCRE is also
+    prone to an error when optimizing character classes containing a
+    singleton UTF-8 sequence which might lead to a heap-based buffer
+    overflow (CVE-2007-4768).
+    </p>
+    <p>
+    Chris Evans also reported multiple integer overflow vulnerabilities in
+    PCRE when processing a large number of named subpatterns ("name_count")
+    or long subpattern names ("max_name_size") (CVE-2006-7227), and via
+    large "min", "max", or "duplength" values (CVE-2006-7228) both possibly
+    leading to buffer overflows. Another vulnerability was reported when
+    compiling patterns where the "-x" or "-i" UTF-8 options change within
+    the pattern, which might lead to improper memory calculations
+    (CVE-2006-7230).
+    </p>
+  </description>
+  <impact type="normal">
+    <p>
+    An attacker could exploit these vulnerabilities by sending specially
+    crafted regular expressions to applications making use of the PCRE
+    library, which could possibly lead to the execution of arbitrary code,
+    a Denial of Service or the disclosure of sensitive information.
+    </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-7.3-r1&quot;</code>
