Summary

The remote host is missing an update to the system as announced in the referenced advisory FreeBSD-SA-09:16.rtld.asc

Insight

Insight

The run-time link-editor, rtld, links dynamic executable with their needed libraries at run-time. It also allows users to explicitly load libraries via various LD_ environmental variables. When running setuid programs rtld will normally remove potentially dangerous environment variables. Due to recent changes in FreeBSD environment variable handling code, a corrupt environment may result in attempts to unset environment variables failing.

Solution

Solution

Upgrade your system to the appropriate stable release or security branch dated after the correction date https://secure1.securityspace.com/smysecure/catid.html?in=FreeBSD-SA-09:16.rtld.asc
