[GLSA-200504-25] Rootkit Hunter: Insecure temporary file creation

Vulnerability Assessment Summary
Rootkit Hunter: Insecure temporary file creation

Detailed Explanation for this Vulnerability Assessment
The remote host is affected by the vulnerability described in GLSA-200504-25
(Rootkit Hunter: Insecure temporary file creation)


Sune Kloppenborg Jeppesen and Tavis Ormandy of the Gentoo Linux
Security Team have reported that the check_update.sh script and the
main rkhunter script 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 rkhunter or the check_update.sh script 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.
