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

low Nessus Plugin ID 18146

Synopsis

The remote Gentoo host is missing one or more security-related patches.

Description

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.

Solution

All Rootkit Hunter users should upgrade to the latest version:
 # emerge --sync # emerge --ask --oneshot --verbose '>=app-forensics/rkhunter-1.2.3-r1'
