The remote Ubuntu 16.04 ESM host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-5795-2 advisory.
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. (CVE-2022-44792)
handle_ipv6IpForwarding in agent/mibgroup/ip-mib/ip_scalars.c in Net-SNMP 5.4.3 through 5.9.3 has a NULL Pointer Exception bug that can be used by a remote attacker to cause the instance to crash via a crafted UDP packet, resulting in Denial of Service. (CVE-2022-44793)
A flaw was found in net-snmp. A buffer overflow in the handling of the INDEX of NET-SNMP-VACM-MIB can cause an out-of-bounds memory access issue. (CVE-2022-24805)
A flaw was found in net-snmp. This issue occurs due to improper input validation when simultaneously setting malformed OIDs in the master agent and subagent. (CVE-2022-24806)
A flaw was found in net-snmp. A malformed OID in a SET request to the SNMP-VIEW-BASED-ACM- MIB::vacmAccessTable can cause an out-of-bounds memory access issue. (CVE-2022-24807)
A flaw was found in net-snmp. A malformed OID in a SET request to NET-SNMP-AGENT-MIB::nsLogTable can cause a NULL pointer dereference issue. (CVE-2022-24808)
A flaw was found in net-snmp. A malformed OID in a GET-NEXT to the nsVacmAccessTable can cause a NULL pointer dereference issue. (CVE-2022-24809)
A flaw was found in net-snmp. A malformed OID in a SET to the nsVacmAccessTable can cause a NULL pointer dereference issue. (CVE-2022-24810)
Note that Nessus has not tested for these issues but has instead relied only on the application’s self-reported version number.
