+Subject: [PATCH 1/2] isohybrid: fix overflow on 32 bit system
+
+When call isohybrid with option '-u', it overflows on a 32 bits host. It
+seeks to 512 bytes before the end of the image to install gpt header. If
+the size of image is larger than LONG_MAX, it overflows fseek() and
+cause error:
+
+isohybrid: image-x86-64-20140505110100.iso: seek error - 8: Invalid argument
+
+Replace fseek with fseeko to fix this issue.
