Php: Security Vulnerabilities
The strip_tags function in PHP 4.x up to 4.3.7, and 5.x up to 5.0.0RC3, does not filter null (\0) characters within tag names when restricting input to allowed tags, which allows dangerous tags to be processed by web browsers such as Internet Explorer and Safari, which ignore null characters and facilitate the exploitation of cross-site scripting (XSS) vulnerabilities.

PHP treats unknown methods such as "PoSt" as a GET request, which could allow attackers to intended access restrictions if PHP is running on a server that passes on all methods, such as Apache httpd 2.0, as demonstrated using a Limit directive. NOTE: this issue has been disputed by the Apache security team, saying "It is by design that PHP allows scripts to process any request method. A script which does not explicitly verify the request method will hence be processed as normal for arbitrary methods. It is therefore expected behaviour that one cannot implement per-method access control using the Apache configuration alone, which is the assumption made in this report.

Buffer overflow in the imap_fetch_overview function in the IMAP functionality (php_imap.c) in PHP before 4.3.3 allows remote attackers to cause a denial of service (segmentation fault) and possibly execute arbitrary code via a long e-mail address in a (1) To or (2) From header.

The php_check_safe_mode_include_dir function in fopen_wrappers.c of PHP 4.3.x returns a success value (0) when the safe_mode_include_dir variable is not specified in configuration, which differs from the previous failure value and may allow remote attackers to exploit file include vulnerabilities in PHP applications.
