SGI Security Advisory
Title : Multiple Vulnerabilities in BIND Name Service Daemon
Number : 20021201-01-P
Date : December 4, 2002
Reference: CERT CA-2002-31, VU#844360, VU#852283
Reference: CVE CAN-2002-0029, CAN-2002-1219
Reference: ISS X-Force Alert #21469
Reference: SGI BUGS 873320 873381
Fixed in : IRIX 6.5.19 or patch 4881
______________________________________________________________________________
- -----------------------
- --- Issue Specifics ---
- -----------------------
The BIND distribution provides Internet domain name service known as DNS.
ISC and CERT have reported several vulnerabilities discovered in
certain versions of BIND distributions. These vulnerabilities can be
used to perform denial of service attacks and/or to obtain privileged
access remotely.
See the following URLs for additional information:
http://www.cert.org/advisories/CA-2002-31.htmlhttp://bvlive01.iss.net/issEn/delivery/xforce/alertdetail.jsp?oid=21469http://www.isc.org/products/BIND/bind-security.html
CERT assigned the following CVE candidates to these issues:
http://cve.mitre.org/cgi-bin/cvename.cgi?name=CAN-2002-0029http://cve.mitre.org/cgi-bin/cvename.cgi?name=CAN-2002-1219
SGI has investigated the issue and provides the following information for
customer interpretation and possible action.
- --------------
- --- Impact ---
- --------------
SGI distributes BIND with IRIX 6.5, but it is not installed by default.
It is part of an optional package called eoe.sw.named.
To determine the version of IRIX you are running, execute the following
command:
# uname -R
That will return a result similar to the following:
# 6.5 6.5.16f
The first number ("6.5") is the release name, the second ("6.5.16f" in this
case) is the extended release name. The extended release name is the
"version" we refer to throughout this document.
To see if BIND is installed, execute the following command:
% versions eoe.sw.named
I = Installed, R = Removed
Name Date Description
I eoe 12/12/2001 IRIX Execution Environment, 6.5.14f
I eoe.sw 12/12/2001 IRIX Execution Environment Software
I eoe.sw.named 12/12/2001 Berkeley Internet Name Domain Server
These vulnerabilities have been publicly discussed in public Usenet
newsgroups and Internet mailing lists.
- --------------------------
- --- Temporary Solution ---
- --------------------------
Unfortunately, there are no effective workarounds for this issue.
However, if patch 4725 is applied and configured in a chroot-ed manner,
some of the exposure to the vulnerability can be minimized.
SGI recommends either installing the appropriate patch from the list below
or upgrading to IRIX 6.5.19 when it is released.
- ----------------
- --- Solution ---
- ----------------
SGI has provided a patch for these vulnerabilities. Our recommendation is to
upgrade to IRIX 6.5.19 when available, or install the appropriate patch.
