Patch-ID# 100296-02 Keywords: nfs rpc mount exportfs Synopsis: SunOS 4.1, 4.1.1, 4.1.2: netgroup exports to world Date: 16/Oct/91 SunOS release: 4.1, 4.1_PSR_A, 4.1.1 4.1.2 Unbundled Product: Unbundled Release: Topic: bug fix BugId's fixed with this patch: 2000680 1044852 1048890 Architectures for which this patch is available: sun3, sun3x, sun4, sun4c sun4m Patches which may conflict with this patch: Obsoleted by: Problem Description: If the cached list of netgroups that a client is not a member of exceeds the cache capacity then the mount daemon will acknowledge the client's membership of any netgroup even if it is not a member. If the access list of hosts is a string under 256 chars then things work as expected, but that if it is longer everyone can mount the filesystem. Additionally this patch also fixes a problem where the cached netgroup entry may contain groups from the previous mount. INSTALL: As root: mv /usr/etc/rpc.mountd /usr/etc/rpc.mountd.FCS cp `arch`/rpc.mountd /usr/etc chown root /usr/etc/rpc.mountd chgrp staff /usr/etc/rpc.mountd chmod 755 /usr/etc/rpc.mountd You will then need to kill the currently running rpc.mountd and restart it as per /etc/rc.local or simply reboot the system.
