NDMP and Tivoli Storage manager
by Pucky, Todd M. 02 Aug '02

02 Aug '02

We currently have a F820 Filer that we backup through an NT box without NDMP, but we are looking to move to NDMP backups as our data load increases. Does anyone have experience using NDMP backups with Tivoli Storage Manager? If so, does it seem to effective? How is your configuration set up? Our current Tivoli environment is a NSM 3466 with a 3494 Automated Tape Library. Any advice would be greatly appreciated.

Sun RPC xdr_array buffer overflow
by Brian Tao 01 Aug '02

01 Aug '02

What's Netapp's position on DOT's implementation of the RPC mechanism? -- Brian Tao (BT300, taob(a)risc.org) "Though this be madness, yet there is method in't" ---------- Forwarded message ---------- From: Dave Ahmad <da(a)securityfocus.com> To: bugtraq(a)securityfocus.com Date: Wed, 31 Jul 2002 11:05:00 -0600 (MDT) Subject: [Bugtraq] Remote Buffer Overflow Vulnerability in Sun RPC -----BEGIN PGP SIGNED MESSAGE----- Internet Security Systems Security Brief July 31, 2002 Remote Buffer Overflow Vulnerability in Sun RPC Synopsis: Internet Security Systems (ISS) X-Force has discovered a buffer overflow in the xdr_array filter primitive. This function is a part of the Sun RPC library, and it is used in multiple RPC services. Any native or third party software that uses the xdr_array function may be vulnerable. Vulnerable RPC services are installed and enabled by default on the affected software versions. Impact: The buffer overflow vulnerability can allow remote attackers to execute arbitrary commands on a target system with superuser privileges. Attackers pose the most serious risk when attacking unprotected networks, or improperly protected networks Affected Versions: Sun Microsystems Solaris 2.5.1 Sun Microsystems Solaris 2.6 Sun Microsystems Solaris 7 Sun Microsystems Solaris 8 Sun Microsystems Solaris 9 Note: The versions above were tested and found to be vulnerable. Additional commercial and open-source Unix operating systems use implementations of Sun RPC, and may also be vulnerable.

Background Sun RPC is a remote procedure call framework which allows clients to invoke procedures in a server process over a network somewhat transparently. XDR is a mechanism for encoding data structures for use with RPC. NFS, NIS, and many other network services are built upon Sun RPC. The FreeBSD C runtime library (libc) contains an XDR encoder/decoder derived from Sun's RPC implementation. II. Problem Description An error in the calculation of memory needed for unpacking arrays in the XDR decoder can result in a heap buffer overflow. III. Impact Any application using Sun RPC may be vulnerable to the heap buffer overflow. Depending upon the application, this vulnerability may be exploitable and lead to arbitrary code execution. Though no exploits are known to exist currently, many RPC-based services run as the superuser (such as NFS, the NIS server, rpc.statd, and others) and thus this vulnerability should be considered high-risk. No RPC-based services are enabled by default in FreeBSD installations. IV. Workaround Do not run any RPC-based services. The RPC-based services running on a machine may be determined by: # rpcinfo -p <hostname> To disable any RPC-based services at next boot, add (or change if it is already present) the following lines in /etc/rc.conf: portmap_enable="NO" nfs_client_enable="NO" nfs_server_enable="NO" nis_client_enable="NO" nis_server_enable="NO" V. Solution Do one of the following: 1) Upgrade your vulnerable system to 4.6-STABLE; or to the RELENG_4_6, RELENG_4_5, or RELENG_4_4 security branch dated after the correction date (4.6.1-RELEASE-p4, 4.5-RELEASE-p12, or 4.4-RELEASE-p19). 2) To patch your present system: The following patch has been verified to apply to FreeBSD 4.4, 4.5, and 4.6 systems. a) Download the relevant patch from the location below, and verify the detached PGP signature using your PGP utility. # fetch ftp://ftp.FreeBSD.org/pub/FreeBSD/CERT/patches/SA-02:34/rpc.patch # fetch ftp://ftp.FreeBSD.org/pub/FreeBSD/CERT/patches/SA-02:34/rpc.patch.asc b) Execute the following commands as root: # cd /usr/src # patch < /path/to/patch c) Recompile the operating system as described in <URL:http://www.freebsd.org/doc/handbook/makeworld.html>. Note that any statically linked applications that are not part of the base system (i.e. from the Ports Collection or other 3rd-party sources) must be recompiled if they use Sun RPC. All affected applications must be restarted in order to use the corrected library. Though it is not required, rebooting may be the easiest way to accomplish this. VI. Correction details The following list contains the revision numbers of each file that was corrected in FreeBSD. Path Revision Branch - ------------------------------------------------------------------------- src/lib/libc/xdr/xdr_array.c RELENG_4 1.8.2.2 RELENG_4_6 1.8.10.2 RELENG_4_5 1.8.8.2 RELENG_4_4 1.8.6.2 src/sys/conf/newvers.sh RELENG_4_6 1.44.2.23.2.9 RELENG_4_5 1.44.2.20.2.13 RELENG_4_4 1.44.2.17.2.18 - ------------------------------------------------------------------------- VII.
