Debian DLA-3270-1 : net-snmp - LTS security update

medium Nessus Plugin ID 170055

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-3270 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)

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+deb10u4.
