Description

The 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.

Impact :

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.

Workaround :

There is no known workaround at this time.
