"There has been a long-standing bug in Deadwood (ever since 2007) where
bounds checking for strings was not correctly done under some
circumstances.

Because of this, it has been possible to send Deadwood a 'packet of
death' which will crash Deadwood. Since the attack causes
out-of-bounds memory to be read, but not written to, the impact of the
bug is denial of service. It appears this attack can only be exploited
by an IP with permission to perform recursive queries against
Deadwood.

Note that this bug only affects users of the Deadwood recursive
resolver.

Note that Tenable Network Security has extracted the preceding
description block directly from the Fedora security advisory. Tenable
has attempted to automatically clean and format it as much as possible
without introducing additional issues."
