Описание
An integer underflow in Organization Specific TLV was found in various versions of OpenvSwitch.
A flaw was found in the OpenvSwitch package. If LLDP processing is enabled for a specific port, crafted LLDP packets could cause a data underflow.
Отчет
To exploit this vulnerability, it requires LLDP processing to be enabled for a specific port, which is unlikely to be exploitable in any of the Red Hat products. Considering this restriction, the impact is lowered to moderate.
