Package: php4
Severity: grave
Tags: security
Justification: user security hole

Several security issues are fixed by PHP 4.4.3, including these
which are not yet fixed in the Debian package:


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, and cross-site scripting (XSS)
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().


zend_hash.c in PHP before 5.1.3 can cause the internal zend_hash_del
function 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.
