The rtsol(8) and rtsold(8) programs do not validate the domain search list options provided in router advertisement mess

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.
