TITLE

Contiki-NG Buffer error vulnerability

Trust: 0.8

sources: JVNDB: JVNDB-2018-009398

DESCRIPTION

An issue was discovered in Contiki-NG through 4.1. There is a buffer over-read in lookup in os/storage/antelope/lvm.c while parsing AQL (lvm_register_variable, lvm_set_variable_value, create_intersection, create_union). Contiki-NG Contains a buffer error vulnerability.Information is obtained, information is altered, and service operation is disrupted (DoS) There is a possibility of being put into a state. Attackers can use this vulnerability to cause a denial of service. Contiki-NG is an open source cross-platform operating system for the next generation of IoT devices. The 'lookup' in the os / storage / antelope / lvm.c file in Contiki-NG 4.1 and earlier has a security vulnerability. An attacker could use this vulnerability to execute code (buffer read out of bounds)
