[issue1179] [CVE-2007-4965] Integer overflow in imageop module

[James Antill]

James Antill added the comment:

So I think this is all the places integer overflow checking is needed
in imageop.c and rbgimgmodule.c.
 There might be checks here which can't be exploited anyway, and I
haven't checked any other files yet.

 Feel free to comment.

 Ps. This is against the 2.5 in Fedora-7, but it should apply to upstream.
