TITLE

Brocade Fabric OS Resource management vulnerability

Trust: 0.8

sources: JVNDB: JVNDB-2017-012501

DESCRIPTION

A vulnerability in the IPv6 stack on Brocade Fibre Channel SAN products running Brocade Fabric OS (FOS) versions before 7.4.2b, 8.1.2 and 8.2.0 could allow an attacker to cause a denial of service (CPU consumption and device hang) condition by sending crafted Router Advertisement (RA) messages to a targeted system. Brocade Fabric OS (FOS) Contains a resource management vulnerability.Service operation interruption (DoS) There is a possibility of being put into a state. BrocadeFibreChannelSANproducts are Brocade switches and BrocadeFabricOS (FOS) is an embedded system running on them. Security vulnerabilities exist in BrocadeFibreChannelSAN products prior to BrocadeFOS7.4.2b, pre-8.1.2, and pre-8.0.6 IPv6 stacks. Broadcom Fabric OS is prone to a remote denial-of-service vulnerability. Exploiting this issue allows remote attackers to cause a denial-of-service condition due to excessive CPU consumption. Versions prior to Broadcom Fabric OS 7.4.2b, 8.1.2 and 8.2.0 are vulnerable
