Synopsis
The remote Debian host is missing one or more security-related updates.Description
The remote Debian 10 host has packages installed that are affected by multiple vulnerabilities as referenced in the dla-3088 advisory.- 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 Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.
Solution
Upgrade the net-snmp packages.For Debian 10 buster, these problems have been fixed in version 5.7.3+dfsg-5+deb10u3.
