Stack-based buffer overflow in the GD extension in PHP before 5.2.15 and 5.3.x before 5.3.4 allows context-dependent attackers to cause a denial of service (application crash) via a large number of anti-aliasing steps in an argument to the imagepstext function.

The set_magic_quotes_runtime function in PHP 5.3.2 and 5.3.3, when the MySQLi extension is used, does not properly interact with use of the mysqli_fetch_assoc function, which might make it easier for context-dependent attackers to conduct SQL injection attacks via crafted input that had been properly handled in earlier PHP versions.

strtod.c, as used in the zend_strtod function in PHP 5.2 before 5.2.17 and 5.3 before 5.3.5, and other products, allows context-dependent attackers to cause a denial of service (infinite loop) via a certain floating-point value in scientific notation, which is not properly handled in x87 FPU registers, as demonstrated using 2.2250738585072011e-308.

Double free vulnerability in the imap_do_open function in the IMAP extension (ext/imap/php_imap.c) in PHP 5.2 before 5.2.15 and 5.3 before 5.3.4 allows attackers to cause a denial of service (memory corruption) or possibly execute arbitrary code via unspecified vectors.

Stack consumption vulnerability in the filter_var function in PHP 5.2.x through 5.2.14 and 5.3.x through 5.3.3, when FILTER_VALIDATE_EMAIL mode is used, allows remote attackers to cause a denial of service (memory consumption and application crash) via a long e-mail address string.

Format string vulnerability in stream.c in the phar extension in PHP 5.3.x through 5.3.3 allows context-dependent attackers to obtain sensitive information (memory contents) and possibly execute arbitrary code via a crafted phar:// URI that is not properly handled by the phar_stream_flush function, leading to errors in the php_stream_wrapper_log_error function. NOTE: this vulnerability exists because of an incomplete fix for CVE-2010-2094.
