Synopsis

The remote FreeBSD host is missing a security-related update.

Description

Tim Wojtulewicz of Corelight reports :

Fix potential Undefined Behavior in decode_netbios_name() and decode_netbios_name_type() BIFs. The latter has a possibility of a remote heap-buffer-overread, making this a potential DoS vulnerability.

Add some extra length checking when parsing mobile ipv6 packets. Due to the possibility of reading invalid headers from remote sources, this is a potential DoS vulnerability.

Solution

Update the affected package.
