FreeBSD : mDNSResponder -- corrupted stack crash when parsing bad resolv.conf (1cd87e2a-81e3-11df-81d8-00262d5ed8ee)

Synopsis :

The remote FreeBSD host is missing a security-related update.

Description :

Juli Mallett reports :

mdnsd will crash on some systems with a corrupt stack and once that's
fixed it will still leak a file descriptor when parsing resolv.conf.
The crash is because scanf is used with %10s for a buffer that is only
10 chars long. The buffer size needs increased to 11 chars to hold the
trailing NUL. To fix the leak, an fclose needs added.
