+Subject: [PATCH] Fix uudecode buffer overflow.
+
+mutt_decode_uuencoded() used each line's initial "length character"
+without any validation.  It would happily read past the end of the
+input line, and with a suitable value even past the length of the
+input buffer.
+
+As I noted in ticket 404, there are several other changes that could
+be added to make the parser more robust.  However, to avoid
+accidentally introducing another bug or regression, I'm restricting
+this patch to simply addressing the overflow.
+
+Thanks to Tavis Ormandy for reporting the issue, along with a sample
+message demonstrating the problem.
