Sun 22 May 2016 03:53:01 PM UTC, original submission:

Package: grub
Version: 1:2.02.beta2

See for the buffer overrun message at:
http://elstel.rivido.de/uploads/grub-gzio/screenshot.jpeg

The respective .gz file which can not be unpacked is:
http://elstel.rivido.de/uploads/grub-gzio/fdubcd.img.gz

The following menuentry produces the gzip buffer overrun:

menuentry 'FreeDOS' {
insmod gzio
insmod memdisk
linux16 (hd0,msdos18)/boot/syslinux/memdisk
initrd16 (hd0,msdos18)/ubcd/images/fdubcd.img.gz
}

A similar syslinux entry works fine:

LABEL -
MENU LABEL UBCD FreeDOS R1.52 (Based on NwDsk V3.40)
TEXT HELP
FreeDOS boot disk used to run many of the other DOS apps on the UBCD.
Revised
version of Eric Veermans' FreeDOS NwDsk 3.40. Addresses many bug fixes,
performance enhancements and compatibility issues.

INITRD /ubcd/images/fdubcd.img.gz
