SUMMARY: This bulletin contains information about security vulnerabilities and upgrades for ULTRIX and DEC OSF/1 operating systems. BACKGROUND: The DECNET-ULTRIX V4.2, ULTRIX V4.3 (VAX/RISC), ULTRIX V4.3A (RISC), ULTRIX V4.4 (VAX/RISC), ULTRIX Worksystem Software and DEC OSF/1 V1.2 - V2.0 have security vulnerabilities. Information about these vulnerabilities has been widely distributed on various Internet forums. A security advisory released by Digital Equipment Corporation containing information about upgrades that correct these problems is attached below. IMPACT: Potential security vulnerabilities exist that could allow users to gain root access to DEC systems. RECOMMENDED SOLUTIONS: ASSIST recommends all DoD sites obtain and install the appropriate upgrade package on all affected DoD DEC systems as soon as possible. Review the attached DEC advisory for specifics about DEC system versions affected and upgrade packages available from DEC. <<<<<<<<<<<<<<<<<<<<<<< BEGIN DEC ADVISORY >>>>>>>>>>>>>>>>>>>>>> SOURCE: Digital Equipment Corporation - ( DSIN / DSNlink FLASH MAIL ) Software Security Response Team 17.MAY.94 PRODUCT: ULTRIX Versions 4.3, 4.3A, V4.4 DECnet-ULTRIX Version 4.2 DEC OSF/1 Versions 1.2, 1.3, 1.3A, 2.0 ADVISORY INFORMATION: SUBJECT: Security Enhanced Kit for DECNET-ULTRIX V4.2, ULTRIX V4.3 (VAX/RISC), ULTRIX V4.3A (RISC), ULTRIX V4.4 (VAX/RISC), ULTRIX Worksystem Software and DEC OSF/1 V1.2 - V2.0 IMPACT: Potential security vulnerabilities exist where, under certain circumstances user access or privilege may be expanded. SOLUTION: ULTRIX: Upgrade/Install ULTRIX to an minimum of V4.4 and install the Security Enhanced Kit DEC OSF/1: Upgrade/Install to a minimum of V1.2 and install the Security Enhanced Kit [NOTE: In the text below, Digital identifies OSF/1 V2.0 as the minimum. Digital has confirmed that 2.0 is correct] These kits are available from Digital Equipment Corporation by contacting your normal Digital support channel or by request via DSNlink for electronic transfer. IMPACT: Digital has discovered the existence of potential security vulnerabilities inthe ULTRIX V4.3, V4.3a, V4.4 and DEC OSF/1 V1.2, V1.3, V2.0 Operating Systems, and DECnet-ULTRIX V4.2. These potential vulnerabilities were discovered as a result of evaluating recent reports of potential security vulnerabilities which were distributed on the INTERNET and as a result of Digital's continued engineering efforts. The solutions to these vulnerabilities have been included in the next release of ULTRIX and DEC OSF/1. The kits have been created to correct potential security vulnerabilities which, under certain circumstances may expand user access or privilege. Digital Equipment Corporation strongly urges customers to upgrade to a minimum of ULTRIX V4.4 and DEC OSF/1 V2.0, then apply the Security Enhanced Kit. - Please refer to the applicable Release Note information prior to upgrading your installation.
