Description Jean-François Brunette (RETIRED) 2005-03-25 10:38:21 UTC
Description: Gangstuck and Psirac have reported some vulnerabilities in openMosixview, which can be exploited by malicious, local users to perform certain actions on a vulnerable system with escalated privileges. The vulnerabilities are caused due to various temporary files being created insecurely with predictable filenames. This can be exploited via symlink attacks to create or overwrite arbitrary files on the system with the privileges of the user running openmosixview or the openmosixcollector daemon. The vulnerabilities have been reported in versions 1.5 and prior. Solution: Grant only trusted users access to affected systems

Security please vote on GLSA need
Comment 9 Thierry Carrez (RETIRED) 2005-04-19 00:31:36 UTC
Do openmosixview or the openmosixcollector daemon typically run as root ? If yes, I would issue a GLSA about it, if not, I wouldn't. xmerlin/cluster herd, could you give us your opinion ?
Comment 10 Thierry Carrez (RETIRED) 2005-04-19 11:23:04 UTC
I think it can be run by root quite usually, so I vote YES.
Comment 11 Christian Zoffoli (RETIRED) 2005-04-19 12:13:32 UTC
It needs to be run as root as I can remember
Comment 12 Sune Kloppenborg Jeppesen 2005-04-19 12:29:31 UTC
I vote yes as well.
