https://notcve.org/view.php?id=CVE-2022-24805
net-snmp provides various tools relating to the Simple Network Management Protocol. Prior to version 5.9.2, a buffer overflow in the handling of the `INDEX` of `NET-SNMP-VACM-MIB` can cause an out-of-bounds memory access. A user with read-only credentials can exploit the issue. Version 5.9.2 contains a patch. Users should use strong SNMPv3 credentials and avoid sharing the credentials. • https://bugzilla.redhat.com/show_bug.cgi?id=2103225 https://bugzilla.redhat.com/show_bug.cgi?id=2105238 https://github.com/net-snmp/net-snmp/commit/67ebb43e9038b2dae6e74ae8838b36fcc10fc937 https://github.com/net-snmp/net-snmp/commit/ce66eb97c17aa9a48bc079be7b65895266fa6775 https://lists.debian.org/debian-lts-announce/2022/08/msg00020.html https://lists.fedoraproject.org/archives/list/package-announce@lists.fedoraproject.org/message/FX75KKGMO5XMV6JMQZF6KOG3JPFNQBY7 https://security.gentoo.org/glsa/202210-29 https://www. • CWE-120: Buffer Copy without Checking Size of Input ('Classic Buffer Overflow') CWE-125: Out-of-bounds Read •

https://notcve.org/view.php?id=CVE-2022-24809
net-snmp provides various tools relating to the Simple Network Management Protocol. Prior to version 5.9.2, a user with read-only credentials can use a malformed OID in a `GET-NEXT` to the `nsVacmAccessTable` to cause a NULL pointer dereference. Version 5.9.2 contains a patch. Users should use strong SNMPv3 credentials and avoid sharing the credentials. Those who must use SNMPv1 or SNMPv2c should use a complex community string and enhance the protection by restricting access to a given IP address range. net-snmp proporciona varias herramientas relacionadas con el protocolo simple de administración de red. • https://bugzilla.redhat.com/show_bug.cgi?id=2103225 https://bugzilla.redhat.com/show_bug.cgi?id=2105242 https://github.com/net-snmp/net-snmp/commit/ce66eb97c17aa9a48bc079be7b65895266fa6775 https://lists.debian.org/debian-lts-announce/2022/08/msg00020.html https://lists.fedoraproject.org/archives/list/package-announce@lists.fedoraproject.org/message/FX75KKGMO5XMV6JMQZF6KOG3JPFNQBY7 https://security.gentoo.org/glsa/202210-29 https://www.debian.org/security/2022/dsa-5209 https://access.redhat.com/security/cve&#x • CWE-476: NULL Pointer Dereference •
