Linuxconf on Red Hat Linux 6.0 and earlier does not properly disable PAM-based access to the shutdown command, which could allow local users to cause a denial of service.
The Red Hat Linux su program does not log failed password guesses if the su process is killed before it times out, which allows local attackers to conduct brute force password guessing.
Samba 1.9.18 inadvertently includes a prototype application, wsmbconf, which is installed with incorrect permissions including the setgid bit, which allows local users to read and write files and possibly gain privileges via bugs in the program.
