The utf8_decode function in PHP before 5.3.4 does not properly handle non-shortest form UTF-8 encoding and ill-formed subsequences in UTF-8 data, which makes it easier for remote attackers to bypass cross-site scripting (XSS) and SQL injection protection mechanisms via a crafted string.
The mb_strcut function in Libmbfl 1.1.0, as used in PHP 5.3.x through 5.3.3, allows context-dependent attackers to obtain potentially sensitive information via a large value of the third parameter (aka the length parameter).
fopen_wrappers.c in PHP 5.3.x through 5.3.3 might allow remote attackers to bypass open_basedir restrictions via vectors related to the length of a filename.
The ZipArchive::getArchiveComment function in PHP 5.2.x through 5.2.14 and 5.3.x through 5.3.3 allows context-dependent attackers to cause a denial of service (NULL pointer dereference and application crash) via a crafted ZIP archive.
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.
The strrchr function in PHP 5.2 before 5.2.14 allows context-dependent attackers to obtain sensitive information (memory contents) or trigger memory corruption by causing a userspace interruption of an internal function or handler.
The var_export function in PHP 5.2 before 5.2.14 and 5.3 before 5.3.3 flushes the output buffer to the user when certain fatal errors occur, even if display_errors is off, which allows remote attackers to obtain sensitive information by causing the application to exceed limits for memory, execution time, or recursion.
mysqlnd_wireprotocol.c in the Mysqlnd extension in PHP 5.3 through 5.3.2 allows remote attackers to (1) read sensitive memory via a modified length value, which is not properly handled by the php_mysqlnd_ok_read function; or (2) trigger a heap-based buffer overflow via a modified length value, which is not properly handled by the php_mysqlnd_rset_header_read function.
The php_mysqlnd_read_error_from_line function in the Mysqlnd extension in PHP 5.3 through 5.3.2 does not properly calculate a buffer length, which allows context-dependent attackers to trigger a heap-based buffer overflow via crafted inputs that cause a negative length value to be used.
