[Bug 2060967] Re: noble/rsync buffer overflow detected

[Mitchell Dzurick]

Package is in proposed now. Testing in an LXC container shows a fix of
this behavior.

$ lxc launch ubuntu-daily:noble n

$ lxc shell n

# dpkg -s rsync | grep Version:
Version: 3.2.7-1build2

# rsync -F --delete-after --archive /etc/os-release /tmp/
*** buffer overflow detected ***: terminated
rsync: connection unexpectedly closed (11 bytes received so far) [sender]

Bug description:
  Hi,

  running the following test case in a current (today/2024-04-11) Noble
  install leads to a "buffer overflow detected":

  $ rsync -F --delete-after --archive /etc/fstab 127.0.0.1:/tmp/
  *** buffer overflow detected ***: terminated
  rsync: connection unexpectedly closed (11 bytes received so far) [sender]
  rsync error: error in rsync protocol data stream (code 12) at io.c(231) [sender=3.2.7]

  Original use case for the above striped down rsync options is the
  ansible module "synchronize".
