According to the versions of the net-snmp packages installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :
The vulnerability exists due to a boundary error when handling INDEX of NET-SNMP-VACM-MIB. A remote attacker can trick the victim into loading a specially crafted MIB collection, trigger an out-of-bounds write and execute arbitrary code on the target system. (CVE-2022-24805)
The vulnerability exists due to insufficient validation of user-supplied input when SETing malformed OIDs in master agent and subagent simultaneously. A remote user can pass specially crafted input to the application and perform a denial of service (DoS) attack. (CVE-2022-24806)
The vulnerability exists due to a boundary error in a SET request to SNMP-VIEW-BASED-ACM- MIB::vacmAccessTable. A remote user can pass a malformed OID in a SET request, trigger an out-of-bounds write and execute arbitrary code on the target system. (CVE-2022-24807)
The vulnerability exists due to a NULL pointer dereference error in NET-SNMP-AGENT-MIB::nsLogTable when handling malformed OID in a SET request. A remote user can pass specially crafted data to the application and perform a denial of service (DoS) attack. (CVE-2022-24808)
The vulnerability exists due to a NULL pointer dereference error in nsVacmAccessTable when handling malformed OID in GET-NEXT. A remote user can pass specially crafted data to the application and perform a denial of service (DoS) attack. (CVE-2022-24809)
The vulnerability exists due to a NULL pointer dereference error in nsVacmAccessTable when handling malformed OID in a SET request. A remote user can pass specially crafted data to the application and perform a denial of service (DoS) attack. (CVE-2022-24810)
Note that Tenable Network Security has extracted the preceding description block directly from the EulerOS security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
