A patch was recently proposed: https://bugs.freedesktop.org/attachment.cgi?id=127421 thanks to John Bowler and his detailed analysis of this issue: https://bugs.freedesktop.org/show_bug.cgi?id=98165 Can we have a CVE, now that we know it was an integer overflow and we have a patch? Regards, Gustavo. 2016-10-06 21:02 GMT-03:00 John Bowler <john.cunningham.bowler () gmail com>:
The bug is not specific to librsvg. This instance happens in write_png inside cairo-png.c, but the actual bug is elsewhere. Other exploits probably exist using things other than PNG and SVG. I think this needs to be CVE'ed immediately. -- John Bowler <john.cunningham.bowler () gmail com> +1 (541) 450-9885 PO BOX 3151 KERBY OR 97531-3151 USA
