Description:
A security issue has been reported in FreeBSD, which can be exploited by malicious, local users to gain knowledge of potentially sensitive information.
The problem is caused due to AMD K7/K8 CPUs only saving/restoring certain x87 registers in FXSAVE instructions when an exception is pending. This may leak x87 register information between processes.
