zend_hash_del_key_or_index in zend_hash.c in PHP before 4.4.3 and 5.x before 5.1.3 can cause zend_hash_del to delete the wrong element, which prevents a variable from being unset even when the PHP unset function is called, which might cause the variable's value to be used in security-relevant operations.

Buffer consumption vulnerability in the tempnam function in PHP 5.1.4 and 4.x before 4.4.3 allows local users to bypass restrictions and create PHP files with fixed names in other directories via a pathname argument longer than MAXPATHLEN, which prevents a unique string from being appended to the filename.

Unspecified vulnerability in session.c in PHP before 5.1.3 has unknown impact and attack vectors, related to "certain characters in session names," including special characters that are frequently associated with CRLF injection, SQL injection, cross-site scripting (XSS), and HTTP response splitting vulnerabilities. NOTE: while the nature of the vulnerability is unspecified, it is likely that this is related to a violation of an expectation by PHP applications that the session name is alphanumeric, as implied in the PHP manual for session_name().

The substr_compare function in string.c in PHP 5.1.2 allows context-dependent attackers to cause a denial of service (memory access violation) via an out-of-bounds offset argument.
