[libnbd PATCH] docs: Mention CVE-2023-5871
by Eric Blake
Point to the list archives for more details about the recent fix in
commit 177308adb1. The issue is deemed low risk, but every security
bug should be mentioned.

The URL may change as a result of getting the list migration stable
(doing another re-import to get more than 2 years of list history may
impact things); I'm also trying to figure out if mailman3/hyperkitty
has a way to get a shorter permalink URL under 80 columns that will
point to a given message. So for now, I'll hold off on pushing this
patch until we know we are ready for it.

It's not to do with LUKS. Just about everyone uses LUKS and
libguestfs works fine. It's a bug in the Ubuntu package, try:

[COMMON PATCH v2] mldrivers: look for bootloader config in /boot/grub/grub.cfg in case of UEFI
by Andrey Drobyshev
On some older Debian-based distros (in particular, this is true for
Debian 8) GRUB config file doesn't reside on EFI partition, but rather
at /boot/grub/grub.cfg even if UEFI firmware is being used. As a
result, in the UEFI case we get "error: no bootloader detected". Let's
just append this path to the end of the corresponding list as a workaround
when dealing with UEFI guests.

LIBNBD SECURITY: Assertion failure in nbd_block_status()
by Eric Blake
We have discovered a security flaw with potential minor impact in
libnbd.
Lifecycle
---------
Reported: 2023-10-29 Fixed: 2023-10-31 Published: 2023-10-31
CVE-2023-5871 has been assigned due to a potential for a Denial of
Service attack by a malicious server against certain versions of
libnbd during nbd_block_status(3); it is considered a low severity
flaw.
Credit
------
Reported by Rich Jones (rjones(a)redhat.com) during fuzz tests, patched
by Eric Blake <eblake(a)redhat.com>
Description
-----------
libnbd is a Network Block Device (NBD) client library. The NBD
protocol states that a client can negotiate with a server to enable
64-bit extended headers; when this negotiation is done, a server's
reply to NBD_CMD_BLOCK_STATUS can include a flag field that does not
fit in 32 bits. We recently added the nbd_block_status_64(3) API to
libnbd to handle such server replies gracefully (exposing the full
64-bit reply to the application); but if an application still uses the
older 32-bit nbd_block_status() API when the server sends a large flag
value, a flaw in libnbd meant that the library could die with an
assertion failure triggered by the server, rather than raising an
EOVERFLOW error to indicate that the server's reply could not fit in
the space provided by the application's choice of API.
Test if libnbd is vulnerable
----------------------------
At this time, there are no known NBD servers that provide
meta-contexts with 64-bit flags (most servers lack support for
extended headers altogether; and all meta-contexts supported by the
upcoming qemu 8.2 release are limited to 32-bit flag values), so it is
unlikely to hit the issue in production when talking to a known
server. However, the patch applied to libnbd for this issue includes
instructions for applying a one-byte patch to convert qemu into a
malicious server, to demonstrate that it is easy for an attacker to
generate a malicious server attempting to exploit the Denial of
Service vulnerability. Refer to the libnbd patch if you need
instructions for producing a one-off qemu server that can be used for
probing if libnbd is vulnerable; otherwise, it is recommended that you
upgrade to the latest libnbd if you need the functionality provided by
extended headers.
Libnbd 1.16.x and earlier are not impacted (those versions gracefully
reject an extended response from a malicious server as unknown, since
they lack extended headers support).
Workarounds
-----------
As a mitigating factor, an application can be written to use only
nbd_block_status_64() to ensure the assertion failure in
nbd_block_status() cannot be reached. Compiling libnbd with
assertions disabled will also eliminate the bug, although most distros
follow our recommendation of leaving assertions enabled. Furthermore,
no known production servers (such as nbd-server, qemu-nbd, nbdkit)
support a meta-context that would include a 64-bit status flag. An
application that insists on using TLS to connect only to a known-good
server will never encounter a block status response that would trigger
the assertion failure.
Fixes
-----
The assertion failure was introduced in libnbd v1.17.4 (commit
20dadb0e10). As of this email, all affected branches have been
patched:

[libnbd PATCH] generator: Fix assertion in ext-mode BLOCK_STATUS, CVE-2023-5871
by Eric Blake
Another round of fuzz testing revealed that when a server negotiates
extended headers and replies with a 64-bit flag value where the client
used the 32-bit API command, we were correctly flagging the server's
response as being an EOVERFLOW condition, but then immediately failing
in an assertion failure instead of reporting it to the application.
The following one-byte change to qemu.git at commit fd9a38fd43 allows
the creation of an intentionally malicious server:

Aborted (core dumped)
whereas a fixed libnbd will give:
nbdsh: command line script failed: nbd_block_status: block-status: command failed: Value too large for defined data type
We can either relax the assertion (by changing to 'assert ((len |
flags) <= UINT32_MAX || cmd->error)'), or intentionally truncate flags
to make the existing assertion reliable. This patch goes with the
latter approach.
Sadly, this crash is possible in all existing 1.18.x stable releases,
if they were built with assertions enabled (most distros do this by
default), meaning a malicious server has an easy way to cause a Denial
of Service attack by triggering the assertion failure in vulnerable
clients, so we have assigned this CVE-2023-5871. Mitigating factors:
the crash only happens for a server that sends a 64-bit status block
reply (no known production servers do so; qemu 8.2 will be the first
known server to support extended headers, but it is not yet released);
and as usual, a client can use TLS to guarantee it is connecting only
to a known-safe server. If libnbd is compiled without assertions,
there is no crash or other mistaken behavior; and when assertions are
enabled, the attacker cannot accomplish anything more than a denial of
service.

[PATCH libnbd 0/4] Miscellaneous Rust cleanups
by Richard W.M. Jones
Add an overview libnbd-rust(3) man page pointing to the real
documentation. This is like OCaml & Golang.
When reviewing the real rustdocs I noticed they basically converted
the man pages into plain text, resulting in lots of problems such as
internal links not working, no `code` annotations, etc. So I wrote a
simple POD to rustdoc translator. It is by no means perfect, but it
fixes many of the issues.
Also build the examples, to make sure we don't get any regressions.
Rich.
