Arch Linux Security Advisory ASA-201810-11 ========================================== Severity: High Date : 2018-10-17 CVE-ID : CVE-2015-5621 CVE-2018-18065 Package : net-snmp Type : multiple issues Remote : Yes Link : https://security.archlinux.org/AVG-777 Summary ======= The package net-snmp before version 5.8-1 is vulnerable to multiple issues including arbitrary code execution and denial of service. Resolution ========== Upgrade to 5.8-1. # pacman -Syu "net-snmp>=5.8-1" The problems have been fixed upstream in version 5.8. Workaround ========== None. Description =========== - CVE-2015-5621 (arbitrary code execution) It was discovered that in net-snmp before 5.8 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-2018-18065 (denial of service) A denial of service vulnerability has been discovered in net-snmp before 5.8. The _set_key function in agent/helpers/table_container.c has 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. Impact ====== A remote unauthenticated attacker is able to crash snmpd or potentially execute arbitrary code on the system by sending specially crafted packets.
