FreeBSD : FreeBSD -- Improper environment sanitization in rtld(1) (ad08d14b-ca3d-11df-aade-0050568f000c)

High Nessus Plugin ID 50336


The remote FreeBSD host is missing one or more security-related updates.


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.


Update the affected packages.
