Debian DSA-5209-1 : net-snmp - security update

medium Nessus Plugin ID 164160

Language:

Synopsis

The remote Debian host is missing one or more security-related updates.

Description

The remote Debian 11 host has packages installed that are affected by multiple vulnerabilities as referenced in the dsa-5209 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 the stable distribution (bullseye), these problems have been fixed in version 5.9+dfsg-4+deb11u1.
