Description:
A vulnerability has been reported in FreeBSD, which can be exploited by malicious, local users to gain knowledge of sensitive information or cause a DoS (Denial of Service).
The vulnerability is caused due to an error in "/proc/curproc/cmdline" of the procfs file system and "/proc/self/cmdline" of the linprocfs file system when reading an argument vector from a process address space. This can be exploited to disclose parts of kernel memory or crash a vulnerable system.
Successful exploitation requires that the procfs or linprocfs file system is mounted.
NOTE: "/proc/self/cmdline" is not implemented in FreeBSD 4.x.
