SynopsisThe remote Gentoo host is missing one or more security-related patches.
DescriptionThe remote host is affected by the vulnerability described in GLSA-200705-19 (PHP: Multiple vulnerabilities)
Several vulnerabilities were found in PHP, most of them during the Month Of PHP Bugs (MOPB) by Stefan Esser. The most severe of these vulnerabilities are integer overflows in wbmp.c from the GD library (CVE-2007-1001) and in the substr_compare() PHP 5 function (CVE-2007-1375). Ilia Alshanetsky also reported a buffer overflow in the make_http_soap_request() and in the user_filter_factory_create() functions (CVE-2007-2510, CVE-2007-2511), and Stanislav Malyshev discovered another buffer overflow in the bundled XMLRPC library (CVE-2007-1864). Additionally, the session_regenerate_id() and the array_user_key_compare() functions contain a double-free vulnerability (CVE-2007-1484, CVE-2007-1521). Finally, there exist implementation errors in the Zend engine, in the mb_parse_str(), the unserialize() and the mail() functions and other elements.
Remote attackers might be able to exploit these issues in PHP applications making use of the affected functions, potentially resulting in the execution of arbitrary code, Denial of Service, execution of scripted contents in the context of the affected site, security bypass or information leak.
There is no known workaround at this time.
SolutionAll PHP 5 users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose '>=dev-lang/php-5.2.2' All PHP 4 users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose '>=dev-lang/php-4.4.7'
