haystack strings. In an application that uses this function on
arbitrary untrusted data this could be exploited to crash the PHP
interpreter. (CVE-2006-4485)

An integer overflow was discovered in the PHP memory allocation
handling. On 64-bit platforms, the 'memory_limit' setting was not
enforced correctly. A remote attacker could exploit this to cause a
Denial of Service attack through memory exhaustion. (CVE-2006-4486)

Maksymilian Arciemowicz discovered that security relevant
configuration options like open_basedir and safe_mode (which can be
configured in Apache's httpd.conf) could be bypassed and reset to
their default value in php.ini by using the ini_restore() function.
(CVE-2006-4625)

Stefan Esser discovered that the ecalloc() function in the Zend engine
did not check for integer overflows. This particularly affected the
unserialize() function. In applications which unserialize untrusted
user-defined data, this could be exploited to execute arbitrary code
with the application's privileges. (CVE-2006-4812)");
