Description:
Christian S.J. Peron has reported a security issue in FreeBSD, which can be exploited by malicious, local users to gain knowledge of sensitive information or corrupt data.
The problem is caused due to insecure default permissions on the iir driver (/dev/iir) allowing any user on the system to open the device and send arbitrary commands to the hardware supported by the iir driver.
Successful exploitation may allow disclosure or destruction of data.
Solution:
Update FreeBSD or apply patch.
