Code injection

In Gargoyle OS 1.12.0, when IPv6 is used, a routing loop can occur that generates excessive network traffic between an affected device and its upstream ISP's router. This occurs when a link prefix route points to a point-to-point link, a destination IPv6 address belongs to the prefix and is not a...

CVE-2021-23270

Summary (CVE-2021-23270): Gargoyle OS 1.12.0 exposes a routing-loop condition when using IPv6, causing excessive traffic between the device and its upstream ISP’s router. The issue occurs if a link-prefix route points to a point-to-point link, a destination IPv6 address belongs to that prefix but...
