Recent Red Hat Libnbd Security Vulnerabilities
A flaw was found in libnbd
CVE-2023-5871
5.3 - Medium
- November 27, 2023
A flaw was found in libnbd, due to a malicious Network Block Device (NBD), a protocol for accessing Block Devices such as hard disks over a Network. This issue may allow a malicious NBD server to cause a Denial of Service.
assertion failure
A flaw was found in libnbd
CVE-2023-5215
6.5 - Medium
- September 28, 2023
A flaw was found in libnbd. A server can reply with a block size larger than 2^63 (the NBD spec states the size is a 64-bit unsigned value). This issue could lead to an application crash or other unintended behavior for NBD clients that doesn't treat the return value of the nbd_get_size() function correctly.
Unchecked Return Value
A flaw was found in the copying tool `nbdcopy` of libnbd
CVE-2022-0485
4.8 - Medium
- August 29, 2022
A flaw was found in the copying tool `nbdcopy` of libnbd. When performing multi-threaded copies using asynchronous nbd calls, nbdcopy was blindly treating the completion of an asynchronous command as successful, rather than checking the *error parameter. This could result in the silent creation of a corrupted destination image.
Unchecked Return Value
A flaw was found in libnbd 1.7.3
CVE-2021-20286
2.7 - Low
- March 15, 2021
A flaw was found in libnbd 1.7.3. An assertion failure in nbd_unlocked_opt_go in ilb/opt.c may lead to denial of service.
assertion failure
Structured reply is a feature of the newstyle NBD protocol allowing the server to send a reply in chunks
CVE-2019-14842
9.8 - Critical
- November 26, 2019
Structured reply is a feature of the newstyle NBD protocol allowing the server to send a reply in chunks. A bounds check which was supposed to test for chunk offsets smaller than the beginning of the request did not work because of signed/unsigned confusion. If one of these chunks contains a negative offset then data under control of the server is written to memory before the read buffer supplied by the client. If the read buffer is located on the stack then this allows the stack return address from nbd_pread() to be trivially modified, allowing arbitrary code execution under the control of the server. If the buffer is located on the heap then other memory objects before the buffer can be overwritten, which again would usually lead to arbitrary code execution.
