The vulnerability is caused due to the "_rtld()" function in libexec/rtld-elf/rtld.c not correctly clearing certain dangerous environment variables before executing suid root processes, which can be exploited to execute arbitrary code with root privileges.

It is a pre-released version in order to deliver a module as quickly as possible to our customers that may be useful in some situations.
