Description Todd C. Miller 2021-03-20 10:41:33 MDT

The code in sudo to probe network interfaces doesn't support IPv6.  It should use the SIOCGLIFCONF ioctl where possible (see the if_tcp man page) and SIOCGLIFNUM as well to avoid looping forever.

On Solaris 10/sparc at least it is possible for get_net_ifs() to fail to return.

Support for this will land in sudo 1.9.7.

Comment 2 Todd C. Miller 2021-05-12 07:36:40 MDT

Fixed in sudo 1.9.7
