The addcslashes function in PHP 5.2 through 5.2.13 and 5.3 through 5.3.2 allows context-dependent attackers to obtain sensitive information (memory contents) by causing a userspace interruption of an internal function, related to the call time pass by reference feature.

PHP was updated to version 5.3.3 to fix serveral security issues.

  - An error exists in the function 'fnmatch' that can lead     to stack exhaustion. (CVE-2010-1917)

  - A memory corruption error exists related to call-time     pass by reference and callbacks.

  - The dechunking filter is vulnerable to buffer overflow.

  - An error exists in the sqlite extension that could     allow arbitrary memory access.

  - An error exists in the 'phar' extension related to     string format validation.

  - The functions 'mysqlnd_list_fields' and     'mysqlnd_change_user' are vulnerable to buffer overflow.

  - An information disclosure vulnerability in var_export() when a fatal error occurs.

  - A resource destruction issue in shm_put_var().

  - A possible information leak because of an interruption of XOR operator.

  - A memory corruption issue caused by an unexpected call-time pass by reference and the following memory clobbering through callbacks.

  - A memory corruption issue in parse_str().

  - A memory corruption issue in pack().

  - A memory corruption issue in substr_replace().

  - A memory corruption issue in addcslashes().

  - A stack exhaustion issue in fnmatch().

  - A buffer overflow vulnerability in the dechunking filter.

  - An arbitrary memory access issue in the sqlite extension.

  - A string format validation issue in the phar extension.

  - An unspecified issue relating to the handling of session variable serialization on certain prefix characters.

  - A NULL pointer dereference issue when processing invalid XML-RPC requests.

  - An unserialization issue in SplObjectStorage.

  - Buffer overflow vulnerabilities in mysqlnd_list_fields and mysqlnd_change_user.

  - Buffer overflows when handling error packets in mysqlnd.

Versions of PHP prior to 5.2.14, or 5.3.x prior to 5.3.3 are affected by the following vulnerabilities :

 - An information disclosure vulnerability in 'var_export()' when a fatal error occurs.
 - A resource destruction issue in 'shm_put_var()'.
 - A possible information leak because of an interruption of XOR operator.
 - A memory corruption issue caused by an unexpected call-time pass by reference and the following memory clobbering through callbacks.
 - A memory corruption issue in 'ArrayObject::uasort()'.
 - A memory corruption issue in 'parse_str()'.
 - A memory corruption issue in 'pack()'.
 - A memory corruption issue in 'substr_replace()'.
 - A memory corruption issue in 'addcslashes()'.
 - A stack exhaustion issue in 'fnmatch()'.
 - A buffer overflow vulnerability in the dechunking filter.
 - An arbitrary memory access issue in the sqlite extension.
 - A string format validation issue in the phar extension.
 - An unspecified issue relating to the handling of session variable serialization on certain prefix characters.
 - A NULL pointer dereference issue when processing invalid XML-RPC requests.
 - An unserialization issue in 'SplObjectStorage'.
 - Buffer overflow vulnerabilities in 'mysqlnd_list_fields' and 'mysqlnd_change_user'.
 - Buffer overflows when handling error packets in mysqlnd.
 - A flaw affects 'sqlite_single_query()' and 'sqlite_array_query()' methods included in the 'ext/sqlite/sqlite.c' source file. Specifically, the 'rres' resource is not properly initialized before use which may trigger a double-free condition when an empty query is passed to the 'real_result_dtor()' function.
