-Subject: [PATCH] generator: Fix assertion in ext-mode BLOCK_STATUS,
- CVE-2023-5871
-
-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:

-
-$ nbdsh -c - <<\EOF
-> def f(a,b,c,d):
->   pass
->
-> h.connect_systemd_socket_activation(["/path/to/bad/qemu-nbd",

-> h.block_staus(h.get_size(), 0, f)
-> EOF
-nbdsh: generator/states-reply-chunk.c:626: enter_STATE_REPLY_CHUNK_REPLY_RECV_BS_ENTRIES: Assertion `(len | flags) <= UINT32_MAX' failed.
-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.
