Several remote vulnerabilities have been discovered in PHP, a server-side, HTML-embedded scripting language, which may lead to the execution of arbitrary code. The Common Vulnerabilities and Exposures project identifies the following problems:
It was discovered that an integer overflow in the str_replace() function could lead to the execution of arbitrary code.
It was discovered that a buffer underflow in the sapi_header_op() function could crash the PHP interpreter.
Stefan Esser discovered that a programming error in the wddx extension allows information disclosure.
It was discovered that a format string vulnerability in the odbc_result_all() functions allows the execution of arbitrary code.
It was discovered that super-global variables could be overwritten with session data.
Stefan Esser discovered that the zend_hash_init() function could be tricked into an endless loop, allowing denial of service through resource consumption until a timeout is triggered.
For the stable distribution (sarge) these problems have been fixed in version 4:4.3.10-19.
For the unstable distribution (sid) these problems have been fixed in version 6:4.4.4-9 of php4 and version 5.2.0-9 of php5.
