Description

 FreeBSD contains a flaw that may lead to an unauthorized information disclosure. The issue is triggered when a local user generates a list of network interfaces and the "SIOCGICONF" ioctl fails to zero out the buffer, which may cause up to 12 bytes of potentially sensitive information from previously cached kernel memory to be disclosed to the user process, resulting in a loss of confidentiality.
