From agent99@sgi.com Mon Aug 12 23:00:36 2002 From: SGI Security Coordinator To: agent99@sgi.com Date: Mon, 12 Aug 2002 14:01:29 -0700 (PDT) Subject: Bulk Data Services (BDS) vulnerability on IRIX -----BEGIN PGP SIGNED MESSAGE----- _____________________________________________________________________________ SGI Security Advisory Title: Bulk Data Services (BDS) vulnerability Number: 20020804-01-P Date: August 12, 2002 Reference: CAN-2002-0632 _____________________________________________________________________________ - ----------------------- - --- Issue Specifics --- - ----------------------- It's been reported that under certain conditions, SGI's BDS (Bulk Data Service) software can be tricked to give a client read access to any file on a server system where BDS is running. SGI has investigated the issue and recommends the following steps for neutralizing the exposure. It is HIGHLY RECOMMENDED that these measures be implemented on ALL vulnerable SGI systems. This vulnerability has been fixed with a patch for BDSPro 2.4 and in later versions of BDSPro. - -------------- - --- Impact --- - -------------- BDS is an optional product and is not installed by default. To check if BDS is installed on your system, execute the following command: # versions bds.eoe.server If the output looks like the following, then BDS is installed. I = Installed, R = Removed Name Date Description I bds 01/08/2002 Bulk Data Server, version 2.4 I bds.eoe 01/08/2002 Bulk Data Server Software I bds.eoe.server 01/08/2002 Bulk Data Server Software 2.4 This vulnerability may be exploited by a remote user, and no local account is required. This issue has been corrected in BDSPro 2.5 and later versions. This vulnerability has been assigned the following CVE: http://cve.mitre.org/cgi-bin/cvename.cgi?name=CAN-2002-0632 - ---------------------------- - --- Temporary Workaround --- - ---------------------------- Apart from not running BDSPro, there is no effective workaround available for this issue. See solution section below. - ---------------- - --- Solution --- - ---------------- SGI has provided a patch for these vulnerabilities. The patch relies on hooks in the kernel that are not present until IRIX 6.5.13 to fix the vulnerabilities. SGI recommends either installing the patch for BDSPro 2.4 or upgrading to BDSPro 2.5 or later when it is released (on an IRIX 6.5.13+ system). OS Version Vulnerable?
