there is a symlink handling problem in the pcp suite from SGI. The binary pmpost will follow symlinks, if setuid root this leads to instant root compromise, as found on SuSE 7.1 (I doubt that this a default SuSE package, though).
It would have been nice if you had informed SGI about this problem before mailing to bugtraq. As a temporary workaround, remove setuid from pmpost. Any PCP events from pmie running as a user will not be logged, this is unlikely to be a problem. A full patch will be available tomorrow, after it has been reviewed. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.0.3 (GNU/Linux) Comment: Exmh version 2.1.1 10/15/1999 iD8DBQE7Lw1zi4UHNye0ZOoRAkuiAKCPcvq+v50TVJ1yvoHTv7bvrqaKEACg1L12 cpMAlQsuJjV90ZJ6tXF1PUU= =YBPa -----END PGP SIGNATURE-----
