+  <title>PHP: Multiple vulnerabilities</title>
+  <synopsis>
+    Several vulnerabilities were found and fixed in PHP, ranging from an
+    information leak and a safe_mode restriction bypass to a potential remote
+    execution of arbitrary code.

+  <background>
+    <p>
+    PHP is a general-purpose scripting language widely used to develop
+    web-based applications. It can run inside a web server using the
+    mod_php module or the CGI version of PHP, or can run stand-alone in a
+    CLI.

+    <p>
+    Stefan Esser and Marcus Boerger reported several different issues in
+    the unserialize() function, including serious exploitable bugs in the
+    way it handles negative references (CAN-2004-1019).
+    </p>
+    <p>
+    Stefan Esser also discovered that the pack() and unpack() functions are
+    subject to integer overflows that can lead to a heap buffer overflow
+    and a heap information leak. Finally, he found that the way
+    multithreaded PHP handles safe_mode_exec_dir restrictions can be
+    bypassed, and that various path truncation issues also allow to bypass
+    path and safe_mode restrictions.
+    </p>
+    <p>
+    Ilia Alshanetsky found a stack overflow issue in the exif_read_data()
+    function (CAN-2004-1065). Finally, Daniel Fabian found that addslashes
+    and magic_quotes_gpc do not properly escape null characters and that
+    magic_quotes_gpc contains a bug that could lead to one level directory
+    traversal.
+    </p>
+  </description>
+  <impact type="high">
+    <p>
+    These issues could be exploited by a remote attacker to retrieve web
+    server heap information, bypass safe_mode or path restrictions and
+    potentially execute arbitrary code with the rights of the web server
+    running a PHP application.
+    </p>
+  </impact>
+  <workaround>
+    <p>
+    There is no known workaround at this time.
+    </p>
+  </workaround>
+  <resolution>
+    <p>
+    All PHP users should upgrade to the latest version:
+    </p>
+    <code>
+    # emerge --sync
+    # emerge --ask --oneshot --verbose &quot;&gt;=dev-php/php-4.3.10&quot;</code>
+    <p>
+    All mod_php users should upgrade to the latest version:
+    </p>
+    <code>
+    # emerge --sync
+    # emerge --ask --oneshot --verbose &quot;&gt;=dev-php/mod_php-4.3.10&quot;</code>
+    <p>
+    All php-cgi users should upgrade to the latest version:
+    </p>
+    <code>
+    # emerge --sync
+    # emerge --ask --oneshot --verbose &quot;&gt;=dev-php/php-cgi-4.3.10&quot;</code>
