EulerOS Virtualization 3.0.1.0 : net-snmp (EulerOS-SA-2019-1436)

critical Nessus Plugin ID 124939

Synopsis

The remote EulerOS Virtualization host is missing multiple security updates.

Description

According to the versions of the net-snmp packages installed, the EulerOS Virtualization installation on the remote host is affected by the following vulnerabilities :

- It was discovered that the snmp_pdu_parse() mishandles error codes and is vulnerable to a heap corruption within the parsing of the PDU prior to the authentication process. A remote, unauthenticated attacker could use this flaw to crash snmpd or, potentially, execute arbitrary code on the system with the privileges of the user running snmpd.(CVE-2018-1000116)

- snmp_oid_compare in snmplib/snmp_api.c in Net-SNMP before 5.8 has a NULL Pointer Exception bug that can be used by an unauthenticated attacker to remotely cause the instance to crash via a crafted UDP packet, resulting in Denial of Service.(CVE-2018-18066)

- It was discovered that the snmp_pdu_parse() function could leave incompletely parsed varBind variables in the list of variables. A remote, unauthenticated attacker could use this flaw to crash snmpd or, potentially, execute arbitrary code on the system with the privileges of the user running snmpd.(CVE-2015-5621)

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.

Solution

Update the affected net-snmp packages.
