Comment 1 Joe Orton 2007-04-03 10:11:57 EDT
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)
