How to fix?

A fix was pushed into the master branch but not yet published.

Overview

Affected versions of this package are vulnerable to Out-of-Bounds such that an attacker can send a crafted frame to the device resulting in an out of bounds write in the packet buffer. The overflow can be used to corrupt other packets and the allocator metadata. Corrupting a pointer will easily lead to denial of service. While carefully manipulating the allocator metadata gives an attacker the possibility to write data to arbitrary locations and thus execute arbitrary code.

Workaround

Users who are unable to upgrade to the fixed version should disable support for fragmented IP datagrams.
