- Information about a new vulnerability in the SUN rcp utility
-
- November 1, 1989, 1615 PST
- Number A-5
-
- CIAC has learned of a new vulnerability in the SunOS 4.0.x rcp
- utility (Sun Bug Report number 1017314). This is a different
- vulnerability from the rcp vulnerability described in the CIAC
- bulletin of August 21, 1989.
-
- This new vulnerability can be exploited by any other trusted host
- listed in /etc/hosts.equiv or /.rhosts. This hole can be ex-
- ploited by anyone running NFS (Network File System), and in par-
- ticular by someone who is using a PC to run PC/NFS. This new rcp
- hole affects only SunOS 4.0.x systems; 3.5 systems are not
- affected.
-
- Sun Microsystems will distrubute a patch for this vulnerability
- when version SunOS 4.1 is released. In the meantime, CIAC recom-
- mends that you use the following workaround:
-
- Change the 'nobody'/etc/passwd file entry from
-
- nobody:*:-2:-2::/:
-
- to
-
- nobody:*:65534:65534:Mismatched NFS ID's:/:
-
- If you have already used another workaround for this vulnerability,
- please be advised that other workarounds may cause unexpected sys-
- tem behavior. Several incorrect workarounds have already been dis-
- tributed by organizations outside of DOE.
-
- If you need further information about this problem, please contact:
-
- Ana Maria De Alvare', (415) 422-7007 or FTS 532-7007
- or
- (415) 422-8193 or FTS 532-8193
-
- or send electronic mail to: ciac@tiger.llnl.gov
-
- CIAC FAX: (415) 422-4294 or FTS 532-4294
-
-
- P.S.--CIAC also advises that if you run SunOS 4.0.3, you should re-
- move the + in the /etc/hosts.equiv file unless you are running YP.
