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):
* https://github.com/advisories/GHSA-q9rw-8758-hccj
Update to version 3.23:
* 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

* 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
