A buffer overflow in the imageloadfont() function in PHP allowed
context-dependent attackers to cause a denial of service (crash)
and potentially execute arbitrary code via a crafted font file
(CVE-2008-3658).

A buffer overflow in the memnstr() function allowed context-dependent
attackers to cause a denial of service (crash) and potentially execute
arbitrary code via the delimiter argument to the explode() function
(CVE-2008-3659).

PHP, when used as a FastCGI module, allowed remote attackers to cause
a denial of service (crash) via a request with multiple dots preceding
the extension (CVE-2008-3660).

The updated packages have been patched to correct these issues.
