CVE ID:	CVE-2009-4146
Description:	The _rtld function in the Run-Time Link-Editor (rtld) in libexec/rtld- elf/rtld.c in FreeBSD 7.1, 7.2, and 8.0 does not clear the LD_PRELOAD environment variable, which allows local users to gain privileges by executing a setuid or setguid program with a modified LD_PRELOAD variable containing an untrusted search path that points to a Trojan horse library, a different vector than CVE-2009-4147.
Test IDs:	1.3.6.1.4.1.25623.1.0.66354
