GLSA-200504-20 : openMosixview: Insecure temporary file creation
Low Nessus Plugin ID 18116
SynopsisThe remote Gentoo host is missing one or more security-related patches.
DescriptionThe remote host is affected by the vulnerability described in GLSA-200504-20 (openMosixview: Insecure temporary file creation)
Gangstuck and Psirac from Rexotec discovered that openMosixview insecurely creates several temporary files with predictable filenames.
A local attacker could create symbolic links in the temporary files directory, pointing to a valid file somewhere on the filesystem.
When openMosixView or the openMosixcollector daemon runs, this would result in the file being overwritten with the rights of the user running the utility, which could be the root user.
There is no known workaround at this time.
SolutionAll openMosixview users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose '>=sys-cluster/openmosixview-1.5-r1'
