|Gentoo Linux Security Advisory
Title: NVClock: Insecure file usage (GLSA 200707-08)
Date: July 24, 2007
A vulnerability has been discovered in NVClock, allowing for the execution of arbitrary code.
NVClock is an utility for changing NVidia graphic chipsets internal frequency.
Vulnerable: < 0.7-r2
Unaffected: >= 0.7-r2
Architectures: All supported architectures
Tavis Ormandy of the Gentoo Linux Security Team discovered that NVClock makes usage of an insecure temporary file in the /tmp directory.
A local attacker could create a specially crafted temporary file in /tmp to execute arbitrary code with the privileges of the user running NVCLock.
There is no known workaround at this time.
All NVClock users should upgrade to the latest version:
|# emerge --sync
# emerge --ask --oneshot --verbose ">=media-video/nvclock-0.7-r2"
