Description
systeminfo.c for Sun Solaris allows local users to read kernel memory via a 0 variable count argument to the sysinfo system call, which causes a -1 argument to be used by the copyout function. NOTE: this issue has been referred to as an integer overflow, but it is probably more like a signedness error or integer underflow.
