CVE-2007-1484

Status Candidate

Overview

The array_user_key_compare function in PHP 4.4.6 and earlier, and 5.x up to 5.2.1, makes erroneous calls to zval_dtor, which triggers memory corruption and allows local users to bypass safe_mode and execute arbitrary code via a certain unset operation after array_user_key_compare has been called.

Gentoo Linux Security Advisory 200705-19: Posted May 31, 2007; Authored by Gentoo | Site security.gentoo.org; Gentoo Linux Security Advisory GLSA 200705-19 - 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 and in the substr_compare() PHP 5 function. Ilia Alshanetsky also reported a buffer overflow in the make_http_soap_request() and in the user_filter_factory_create() functions, and Stanislav Malyshev discovered another buffer overflow in the bundled XMLRPC library. Additionally, the session_regenerate_id() and the array_user_key_compare() functions contain a double-free vulnerability. Finally, there exist implementation errors in the Zend engine, in the mb_parse_str(), the unserialize() and the mail() functions and other elements. Versions less than 5.2.2 are affected.; tags | advisory, overflow, php, vulnerability; systems | linux, gentoo; advisories | CVE-2007-1001, CVE-2007-1285, CVE-2007-1286, CVE-2007-1484, CVE-2007-1521, CVE-2007-1583, CVE-2007-1700, CVE-2007-1701, CVE-2007-1711, CVE-2007-1717, CVE-2007-1718, CVE-2007-1864, CVE-2007-1900, CVE-2007-2509, CVE-2007-2510, CVE-2007-2511; SHA-256 | 85b7223b6bfd70f54588716713c6a4f7ef1cdaf921d40a164c836fe16bbb3b6f; Download | Favorite | View
