Descriptions
In the Linux kernel before 4.20.12, net/ipv4/netfilter/nf_nat_snmp_basic_main.c in the SNMP NAT module has insufficient ASN.1 length checks (aka an array index error), making out-of-bounds read and write operations possible, leading to an OOPS or local privilege escalation. This affects snmp_version and snmp_helper.
En el kernel de Linux, en versiones anteriores a la 4.20.12, net/ipv4/netfilter/nf_nat_snmp_basic_main.c en el módulo SNMP NAT tiene comprobaciones de longitud ASN.1 insuficientes (conocido como error de índice de arrays), lo que hace que las operaciones de lectura y escritura fuera de límites sean posibles y conduciendo a un OOPS o al escalado de privilegios locales. Esto afecta a snmp_version y snmp_helper.
