Description of problem: An integer overflow exists in the wbmp handling in the copy of the gd library which is bundled in the "gd" extension: http://cvs.php.net/viewvc.cgi/php-src/ext/gd/libgd/gdhelpers.h?r1=1.2.2.3&r2=1.2.2.3.4.1&diff_format=u
Additionally, per bug 224607, Kees Cook from Ubuntu reported a "off-the-end-of-string increment", which could theoretically lead ot a buffer overflow. This flaw would only be exploitable if a JIS-encoded font is used when processing a special malicious string. (CVE-2007-0455; Impact: Low)
