  - CVE-2022-26495: Fixed an integer overflow with a resultant heap-based
       buffer overflow (bsc#1196827).

  - CVE-2022-26496: Fixed a stack-based buffer overflow when parsing the
       name field by sending a crafted NBD_OPT_INFO (bsc#1196828).
  Update to version 3.24 (bsc#1196827, bsc#1196828, CVE-2022-26495,
     CVE-2022-26496):

  * Don't overwrite the hostname with the TLS hostname
  Update to version 3.22:

  - nbd-server: handle auth for v6-mapped IPv4 addresses

  - nbd-client.c: parse the next option in all cases

  - configure.ac: silence a few autoconf 2.71 warnings

  - spec: Relax NBD_OPT_LIST_META_CONTEXTS

  - client: Don't confuse Unix socket with TLS hostname

  - server: Avoid deprecated g_memdup
  Update to version 3.21:

  - Fix --disable-manpages build

  - Fix a bug in whitespace handling regarding authorization files

  - Support client-side marking of devices as read-only

  - Support preinitialized NBD connection (i.e., skip the negotiation).

  - Fix the systemd unit file for nbd-client so it works with netlink (the
         more common situation nowadays)
  Update to 3.20.0 (no changelog)
  Update to version 3.19.0:

  * Better error messages in case of unexpected disconnects

  * Better compatibility with non-bash sh implementations (for
         configure.sh)

  * Fix for a segfault in NBD_OPT_INFO handling

  * The ability to specify whether to listen on both TCP and Unix domain
         sockets, rather than to always do so

  * Various minor editorial and spelling fixes in the documentation.
  Update to version 1.18.0:

  * Client: Add the '-g' option to avoid even trying the NBD_OPT_GO message

  * Server: fixes to inetd mode

  * Don't make gnutls and libnl automagic.

  * Server: bugfixes in handling of some export names during verification.

  * Server: clean supplementary groups when changing user.

  * Client: when using the netlink protocol, only set a timeout when there
         actually is a timeout, rather than defaulting to 0 seconds

  * Improve documentation on the nbdtab file

  * Minor improvements to some error messages

  * Improvements to test suite so it works better on non-GNU userland
         environments

  - Update to version 1.17.0:

  * proto: add xNBD command NBD_CMD_CACHE to the spec

  * server: do not crash when handling child name

  * server: Close socket pair when fork fails");
