Synopsis

The remote Ubuntu host is missing one or more security updates.

Description

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.
