(NVClock: Insecure file usage)
Tavis Ormandy of the Gentoo Linux Security Team discovered that NVClock
makes usage of an insecure temporary file in the /tmp directory.
Impact :
A local attacker could create a specially crafted temporary file in
/tmp to execute arbitrary code with the privileges of the user running
NVCLock.
Workaround :
There is no known workaround at this time."
