CVE-2022-44792 – net-snmp: NULL Pointer Exception when handling ipDefaultTTL
https://notcve.org/view.php?id=CVE-2022-44792
handle_ipDefaultTTL in agent/mibgroup/ip-mib/ip_scalars.c in Net-SNMP 5.8 through 5.9.3 has a NULL Pointer Exception bug that can be used by a remote attacker (who has write access) to cause the instance to crash via a crafted UDP packet, resulting in Denial of Service. handle_ipDefaultTTL en agent/mibgroup/ip-mib/ip_scalars.c en Net-SNMP 5.8 a 5.9.3 tiene un error de excepción de puntero NULL que puede ser utilizado por un atacante remoto (que tiene acceso de escritura) para provocar que la instancia se bloquee a través de un paquete UDP elaborado, lo que resulta en una Denegación de Servicio. A vulnerability was found in Net-SNMP. This issue occurs because the handle_ipDefaultTTL function in agent/mibgroup/ip-mib/ip_scalars.c in Net-SNMP has a NULL Pointer Exception flaw that allows a remote attacker (who has to write access) to cause the instance to crash via a crafted UDP packet, resulting in a denial of service. • https://gist.github.com/menglong2234/b7bc13ae1a144f47cc3c95a7ea062428 https://github.com/net-snmp/net-snmp/issues/474 https://lists.debian.org/debian-lts-announce/2023/01/msg00010.html https://security.netapp.com/advisory/ntap-20230223-0011 https://access.redhat.com/security/cve/CVE-2022-44792 https://bugzilla.redhat.com/show_bug.cgi?id=2141897 • CWE-476: NULL Pointer Dereference •

CVE-2022-43945 – kernel: nfsd buffer overflow by RPC message over TCP with garbage data
https://notcve.org/view.php?id=CVE-2022-43945
The Linux kernel NFSD implementation prior to versions 5.19.17 and 6.0.2 are vulnerable to buffer overflow. NFSD tracks the number of pages held by each NFSD thread by combining the receive and send buffers of a remote procedure call (RPC) into a single array of pages. A client can force the send buffer to shrink by sending an RPC message over TCP with garbage data added at the end of the message. The RPC message with garbage data is still correctly formed according to the specification and is passed forward to handlers. Vulnerable code in NFSD is not expecting the oversized request and writes beyond the allocated buffer space. • http://packetstormsecurity.com/files/171289/Kernel-Live-Patch-Security-Notice-LNS-0092-1.html https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=f90497a16e434c2211c66e3de8e77b17868382b8 https://security.netapp.com/advisory/ntap-20221215-0006 https://access.redhat.com/security/cve/CVE-2022-43945 https://bugzilla.redhat.com/show_bug.cgi?id=2141752 • CWE-131: Incorrect Calculation of Buffer Size CWE-770: Allocation of Resources Without Limits or Throttling •
CVE-2022-40304 – libxml2: dict corruption caused by entity reference cycles
https://notcve.org/view.php?id=CVE-2022-40304
An issue was discovered in libxml2 before 2.10.3. Certain invalid XML entity definitions can corrupt a hash table key, potentially leading to subsequent logic errors. In one case, a double-free can be provoked. Se descubrió un problema en libxml2 antes de la versión 2.10.3. Ciertas definiciones de entidades XML no válidas pueden dañar la clave de una tabla hash, lo que podría provocar errores lógicos posteriores. • http://seclists.org/fulldisclosure/2022/Dec/21 http://seclists.org/fulldisclosure/2022/Dec/24 http://seclists.org/fulldisclosure/2022/Dec/25 http://seclists.org/fulldisclosure/2022/Dec/26 http://seclists.org/fulldisclosure/2022/Dec/27 https://gitlab.gnome.org/GNOME/libxml2/-/commit/1b41ec4e9433b05bb0376be4725804c54ef1d80b https://gitlab.gnome.org/GNOME/libxml2/-/tags https://gitlab.gnome.org/GNOME/libxml2/-/tags/v2.10.3 https://security.netapp.com/advisory/ntap-20221209-0003 • CWE-415: Double Free •
