The rtsol(8) and rtsold(8) programs do not validate the domain + search list options provided in router advertisement messages; the + option body is passed to resolvconf(8) unmodified.
+resolvconf(8) is a shell script which does not validate its input. + A lack of quoting meant that shell commands pass as input to + resolvconf(8) may be executed.
+Systems running rtsol(8) or rtsold(8) are vulnerable to remote + code execution from systems on the same network segment. In + particular, router advertisement messages are not routable and + should be dropped by routers, so the attack does not cross network + boundaries.
+ +In some cases, the `tcp-setmss` handler may free the packet + data and throw an error without halting the rule processing engine. + A subsequent rule can then allow the traffic after the packet data + is gone, resulting in a NULL pointer dereference.
+Maliciously crafted packets sent from a remote host may result + in a Denial of Service (DoS) if the `tcp-setmss` directive is used + and a subsequent rule would allow the traffic to pass.
