Description

This update for net-snmp fixes the following issues :

Security issues fixed :

CVE-2018-18065: _set_key in agent/helpers/table_container.c had a NULL Pointer Exception bug that can be used by an authenticated attacker to remotely cause the instance to crash via a crafted UDP packet, resulting in Denial of Service. (bsc#1111122)

Non-security issues fixed: swintst_rpm: Protect against unspecified Group name (bsc#1102775)

Add tsm and tlstm MIBs and the USM security module. (bsc#1081164)

Fix agentx freezing on timeout (bsc#1027353)

Note that Tenable Network Security has extracted the preceding description block directly from the SUSE security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
