SUMMARY: This bulletin contains information about vulnerabilities in the SCO Unix operating system and a security advisory released by SCO. SCO C2 systems may also be affected by these vulnerabilities. BACKGROUND: The at(C), login(M), prwarn(C) sadc(ADM), and pt_chmod programs included in the SCO Unix software contain security vulnerablities. Detailed information about how to exploit these problems is known to have been released in various Internet discussion forums. IMPACT: Any user with an account on a SCO UNIX system can obtain root privileges using any one of the programs listed. RECOMMENDED SOLUTION: A SCO advisory that addresses these problems and provides solutions follows. ASSIST recommends all DoD elements with SCO systems affected by these vulnerabilities install the appropriate patches as soon as possible. ======================================================================== SCO Advisory 94:001 November 30th, 1994 Patches for at(C), login(M), prwarn(C), sadc(ADM), pt_chmod - ------------------------------------------------------------------------ The Santa Cruz Operation has been informed of the following problems present in our software. I. Description The programs at(C), login(M), prwarn(C) sadc(ADM), and pt_chmod may each allow unauthorized root access to the system. There are four unrelated issues present, one for each program listed above. II. Impact Any user with an account on the system may obtain root access using any one of the programs listed. III. Releases These problems exist on the following releases of SCO Products: SCO Unix System V/386 Release 3.2 Versions 4.2, 4.1, and 4.0 SCO Open Desktop Lite Release 3.0 SCO Open Desktop Release 3.0 and 2.0 SCO Open Server Network System Release 3.0 SCO Open Server Enterprise System Release 3.0 IV. Solution SCO is providing the following (S)ystem (S)ecurity (E)nhancements, SSEs, to address these problems. These are preliminary patches which SCO feels addresses the issues at hand, but these patches have not been fully tested and integrated and hence cannot officially be supported. Official patches should be available in the near future via a (S)upport (L)evel (S)upplement. (SLS). The README file mentioned below will be updated when an official Supplement is available. Binary Patch ------ ------ at(C) sse001 login(M) sse002 prwarn(C) sse003 sadc(ADM) sse004 pt_chmod sse005 These are available at the following sites: Anonymous ftp: ftp.sco.COM:/SSE UUCP downloading, and SOS access: sosco (USA), scolon (Europe), in the directory /usr/spool/uucppublic/SSE.

Binaries acquired from this directory are to be considered preliminary fixes only, and have not been fully tested or integrated. As such, these patches are not officially supported. They are provided as a timely response to security concerns that have been brought to the attention of The Santa Cruz Operation. When final, approved patches are available, usually by a Support Level Supplement, the README files below will be modified to indicate the existence of the finalized version of the supplement. SCO reserves the right to change the contents of these supplements at any time. The format of the Supplements found here are as follows: ssexxx.tar.Z - a compressed tar file ssexxx.ltr.Z - cover letter, release information, and installation instructions where xxx indicates the number of the supplement. Please note that the ssexxx.tar.Z files are *not* diskette images. After downloading an SSE, uncompress both the tar file and the cover letter. For example, if you were trying to install SSE001, after downloading sse001.tar.Z and ssexxx.ltr.Z, you would uncompress both files: # uncompress ssexxx.tar.Z # uncompress ssexxx.ltr.Z After uncompressing both files, you should then follow the instructions provided in the sse001.ltr file for installation instructions.
