via http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2008-3659:

Buffer overflow in the memnstr function in PHP 4.4.x before 4.4.9 and PHP
5.6 through 5.2.6 allows context-dependent attackers to cause a denial
of service (crash) and possibly execute arbitrary code via the delimiter
argument to the explode function. NOTE: the scope of this issue is limited
since most applications would not use an attacker-controlled delimiter,
but local attacks against safe_mode are feasible.

while the attack vector may be somewhat limited, apparently this vector
is actually used in practice by a number of apps, so we should include
the patch (well we in fact have already incorporated it into the svn
repo, but it has not yet been released):
