PHP — популярный язык сценариев общего назначения, особенно подходящий для веб-разработки.

Integer signedness error in the _zend_mm_alloc_int function in the Zend Memory Manager in PHP 5.2.0 allows remote attackers to execute arbitrary code via a large emalloc request, related to an incorrect signed long cast, as demonstrated via the HTTP SOAP client in PHP, and via a call to msg_receive with the largest positive integer value of maxsize.

Integer overflow in the str_replace function in PHP 4 before 4.4.5 and PHP 5 before 5.2.1 allows context-dependent attackers to execute arbitrary code via a single character search string in conjunction with a long replacement string, which overflows a 32 bit length counter. NOTE: this is probably the same issue as CVE-2007-0906.6.

PHP 4.0.0 through 4.4.6 and 5.0.0 through 5.2.1 allows context-dependent attackers to read arbitrary memory locations via an interruption that triggers a user space error handler that changes a parameter to an arbitrary pointer, as demonstrated via the iptcembed function, which calls certain convert_to_* functions with its input parameters.

Buffer overflow in the sqlite_decode_binary function in the bundled sqlite library in PHP 4 before 4.4.5 and PHP 5 before 5.2.1 allows context-dependent attackers to execute arbitrary code via an empty value of the in parameter, as demonstrated by calling the sqlite_udf_decode_binary function with a 0x01 character.

Integer overflow in the str_replace function in PHP 4.4.5 and PHP 5.2.1 allows context-dependent attackers to have an unknown impact via a single character search string in conjunction with a single character replacement string, which causes an "off by one overflow."

Multiple integer signedness errors in the printf function family in PHP 4 before 4.4.5 and PHP 5 before 5.2.1 on 64 bit machines allow context-dependent attackers to execute arbitrary code via (1) certain negative argument numbers that arise in the php_formatted_print function because of 64 to 32 bit truncation, and bypass a check for the maximum allowable value; and (2) a width and precision of -1, which make it possible for the php_sprintf_appendstring function to place an internal buffer at an arbitrary memory location.

Buffer overflow in the bundled libxmlrpc library in PHP before 4.4.7, and 5.x before 5.2.2, has unknown impact and remote attack vectors.

PHP 4 before 4.4.5 and PHP 5 before 5.2.1, when using an empty session save path (session.save_path), uses the TMPDIR default after checking the restrictions, which allows local users to bypass open_basedir restrictions.

Buffer overflow in the imap_mail_compose function in PHP 5 before 5.2.1, and PHP 4 before 4.4.5, allows remote attackers to execute arbitrary code via a long boundary string in a type.parameters field. NOTE: as of 20070411, it appears that this issue might be subsumed by CVE-2007-0906.3.

Buffer overflow in the php_stream_filter_create function in PHP 5 before 5.2.1 allows remote attackers to cause a denial of service (application crash) via a php://filter/ URL that has a name ending in the '.' character.
