Versions Affected : All verisons prior to FreeNAS 11.3-U5
getfsstat(2) is a system call which provides information about mounted filesystems. The kernel provides compatibility system calls for old versions of the interface.
A bug in an internal interface used by getfsstat(2) compatibility system calls could result in a free of an uninitialized pointer when getfsstat(2) is called with an invalid argument.
No workaround is available.
- Upgrade to FreeNAS 11.3-U5 or later.
