CVE-2007-6285
First published: Wed Dec 19 2007(Updated: )
It was reported to secalert that the autofs defaults do not set the nodev NFS option. <a class="bz_bug_link bz_status_CLOSED bz_closed bz_public " title="CLOSED ERRATA - CVE-2007-5964 autofs defaults don't restrict suid in /net" href="show_bug.cgi?id=410031">bug 410031</a> notes the missing nosuid option by default for the /net autofs filesystems, the fix for that issue did not take into account that there was also a missing nodev option for these filesystems. Without the nodev option, it is possible for an attacker to mount a remote filesystem which could give them access to various devices that should normally have restricted access, such as /dev/mem, and various hardware devices. Acknowledgements: Red Hat would like to thank Tim Baum for reporting this issue.
