CVSS: 6.5EPSS: 0%CPEs: 3EXPL: 1CVE-2023-5215 – Libnbd: crash or misbehaviour when nbd server returns an unexpected block size
https://notcve.org/view.php?id=CVE-2023-5215
28 Sep 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. Se encontró una falla en libnbd. Un servidor puede responder con un tamaño de bloque mayor que 2^63 (la especificación NBD establece que el tamaño es un valor sin signo de 64 bits). • https://access.redhat.com/errata/RHSA-2024:2204 • CWE-241: Improper Handling of Unexpected Data Type CWE-252: Unchecked Return Value •

https://notcve.org/view.php?id=CVE-2023-42753
25 Sep 2023 — An array indexing vulnerability was found in the netfilter subsystem of the Linux kernel. A missing macro could lead to a miscalculation of the `h->nets` array offset, providing attackers with the primitive to arbitrarily increment/decrement a memory buffer out-of-bound. This issue may allow a local user to crash the system or potentially escalate their privileges on the system.

18 Sep 2023 — A flaw was found in glibc. In an extremely rare situation, the getaddrinfo function may access memory that has been freed, resulting in an application crash. This issue is only exploitable when a NSS module implements only the _nss_*_gethostbyname2_r and _nss_*_getcanonname_r hooks without implementing the _nss_*_gethostbyname3_r hook.

18 Sep 2023 — A flaw was found in glibc. When the getaddrinfo function is called with the AF_UNSPEC address family and the system is configured with no-aaaa mode via /etc/resolv.conf, a DNS response via TCP larger than 2048 bytes can potentially disclose stack contents through the function returned address data, and may cause a crash.
