adm-photo.php in PhotoPost PHP 5.0 RC3 does not properly verify administrative privileges before manipulating photos, which could allow remote attackers to manipulate other users' photos.

Cross-site scripting (XSS) vulnerability in setuser.php of the Digitanium addon to PHP-Fusion 5.01 allows remote attackers to inject arbitrary web script or HTML via the (1) user_name or (2) user_pass parameters.

exif.c in PHP before 4.3.11 allows remote attackers to cause a denial of service (memory consumption and crash) via an EXIF header with a large IFD nesting level, which causes significant stack recursion.

SQL injection vulnerability in member.php and possibly other scripts in PhotoPost PHP 5.0 RC3 allows remote attackers to execute arbitrary SQL commands via the uid parameter.

Cross-site scripting (XSS) vulnerability in fusion_core.php for PHP-Fusion 5.x allows remote attackers to inject arbitrary web script or HTML via a message with IMG bbcode containing character-encoded Javascript.

The deserialization code in PHP before 4.3.10 and PHP 5.x up to 5.0.2 allows remote attackers to cause a denial of service and execute arbitrary code via untrusted data to the unserialize function that may trigger "information disclosure, double-free and negative reference index array underflow" results.

Buffer overflow in the exif_read_data function in PHP before 4.3.10 and PHP 5.x up to 5.0.2 allows remote attackers to execute arbitrary code via a long section name in an image file.

The check_referer() function in Formmail.php 5.0 and earlier allows remote attackers to bypass access restrictions via an empty or spoofed HTTP Referer, as demonstrated using an application on the same web server that contains a cross-site scripting (XSS) issue.

SQL injection vulnerability in PHP-Nuke 6.9 and earlier, and possibly 7.x, allows remote attackers to inject arbitrary SQL code and gain sensitive information via (1) the category variable in the Search module or (2) the admin variable in the Web_Links module.

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.
