	The old check was off by a factor of 512 and didn't consider cases where we don't get an exact division. This could lead to an out-of-bounds array access in seek_to_sector(). Signed-off-by: Kevin Wolf <kwolf@redhat.com> Reviewed-by: Laszlo Ersek <lersek@redhat.com>
2014-04-01	bochs: Check extent_size header field (CVE-2014-0142)	Kevin Wolf	1	-0/+8

2014-04-01	bochs: Check catalog_size header field (CVE-2014-0143)	Kevin Wolf	1	-1/+9
