Multiple flaws in Stronghold 4.0 PHP

A flaw in the strip_tags function in PHP, commonly used by PHP scripts to
prevent cross-site scripting attacks by removing HTML tags from
user-supplied form data. HTML tags can, in some cases, be passed intact
through the strip_tags function, which may allow a cross-site scripting
attack. (CVE-2004-0595)

A flaw if the memory_limit configuration setting is enabled in PHP. If a
remote attacker could force the PHP interpreter to allocate more memory
than the memory_limit setting before script execution begins, then the
attacker may be able to supply the contents of a PHP hash table remotely.
This hash table could then be used to execute arbitrary code in the context
of the server. (CVE-2004-0594)

Various flaws, including possible information disclosure, double free, and
negative reference index array underflow in the deserialization code of
PHP. PHP applications may use the unserialize function on untrusted user
data, which could allow a remote attacker to gain access to memory or
potentially execute arbitrary code. (CVE-2004-1019)

Flaws in shmop_write, pack, and unpack PHP functions. These functions are
not normally passed user-supplied data, so would require a malicious PHP
script to be exploited. (CVE-2004-1018)
