Description

The vulnerability allows a local user to escalate privileges on the system.

The vulnerability exists due to array index error in SNMP NAT module (net/ipv4/netfilter/nf_nat_snmp_basic_main.c) when parsing ASN.1-encoded payloads in SNMP messages. A local user can set up new network namespaces that invoke iptables configuration and triggers SNMP translations, cause out-of-bounds read and write operations and execute arbitrary code  on the system with elevated privileges.
