Amazon Linux 2 : net-snmp (ALAS-2024-2402)

medium Nessus Plugin ID 187821

Language:

Synopsis

The remote Amazon Linux 2 host is missing a security update.

Description

The version of net-snmp installed on the remote host is prior to 5.7.2-49. It is, therefore, affected by a vulnerability as referenced in the ALAS2-2024-2402 advisory.

 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)

Tenable has extracted the preceding description block directly from the tested product security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Run 'yum update net-snmp' to update your system.
