CVSS: 6.5EPSS: 0%CPEs: 18EXPL: 0CVE-2023-0751 – GELI silently omits the keyfile if read from stdin
https://notcve.org/view.php?id=CVE-2023-0751
When GELI reads a key file from standard input, it does not reuse the key file to initialize multiple providers at once resulting in the second and subsequent devices silently using a NULL key as the user key file. If a user only uses a key file without a user passphrase, the master key is encrypted with an empty key file allowing trivial recovery of the master key. • https://security.FreeBSD.org/advisories/FreeBSD-SA-23:01.geli.asc • CWE-20: Improper Input Validation •

sys/netinet/tcp_timer.h in FreeBSD before 7.0 contains a denial-of-service (DoS) vulnerability due to improper handling of TSopt on TCP connections. NOTE: This vulnerability only affects products that are no longer supported by the maintainer El archivo sys/netinet/tcp_timer.h en FreeBSD versiones anteriores a 7.0, contiene una vulnerabilidad de denegación de servicio (DoS) debido a un manejo inapropiado de TSopt en conexiones TCP. NOTA: Esta vulnerabilidad sólo afecta a productos que ya no son soportados por el mantenedor. • http://jvn.jp/en/jp/JVN20930118 https://cgit.freebsd.org/src/commit/?id=4dc630cdd2f7a790604d2724ecb19c6aa95130a7 • CWE-755: Improper Handling of Exceptional Conditions •

In FreeBSD 13.0-STABLE before n246941-20f96f215562, 12.2-STABLE before r370400, 11.4-STABLE before r370399, 13.0-RELEASE before p4, 12.2-RELEASE before p10, and 11.4-RELEASE before p13, certain VirtIO-based device models in bhyve failed to handle errors when fetching I/O descriptors. A malicious guest may cause the device model to operate on uninitialized I/O vectors leading to memory corruption, crashing of the bhyve process, and possibly arbitrary code execution in the bhyve process. En FreeBSD versiones 13.0-STABLE anteriores a n246941-20f96f215562, 12.2-STABLE anteriores a r370400, 11.4-STABLE anteriores a r370399, 13.0-RELEASE anteriores a p4, 12.2-RELEASE anteriores a p10, y 11.4-RELEASE anteriores a p13, determinados modelos de dispositivos basados en VirtIO en bhyve presentaban un fallo al manejar los errores cuando se obtenían descriptores de E/S. Un huésped malicioso puede causar al modelo de dispositivo operar en vectores de E/S no inicializados, conllevando a una corrupción de la memoria, un bloqueo del proceso bhyve y, posiblemente, una ejecución de código arbitrario en el proceso bhyve. • https://security.FreeBSD.org/advisories/FreeBSD-SA-21:13.bhyve.asc https://security.netapp.com/advisory/ntap-20210923-0004 • CWE-908: Use of Uninitialized Resource •
