Title:
  extlinux-update sorts kernels in the wrong order due to not using sort
  -Vr, fixed upstream

Status in syslinux:
  Fix Released
Status in “syslinux” package in Ubuntu:
  New
Status in “syslinux” package in Debian:
  Fix Released

Bug description:
  extlinux-update contains the line _VERSIONS="$(cd /boot && ls
  vmlinuz-* | grep -v .dpkg-tmp | sed -e 's|vmlinuz-||g' | sort -nr)",
  which attempts to sort on version numbers numerically.  The problem is
  that in kernel version numbers, 3.10 comes after 3.9, while sort -n
  will sort it before (as 3.10 is numerically lower than 3.90 or 3.9).

  Debian has already fixed it to use the version sort (sort -Vr).

  I think this is worth an SRU as it causes 3.10+ kernels to not be
  booted while any 3.2-3.9 kernels are installed.
