CVE-2024-43167

A NULL pointer dereference flaw was found in the ub_ctx_set_fwd function in
Unbound. This issue could allow an attacker who can invoke specific
sequences of API calls to cause a segmentation fault. When certain API
functions such as ub_ctx_set_fwd and ub_ctx_resolvconf are called in a
particular order, the program attempts to read from a NULL pointer, leading
to a crash. This issue can result in a denial of service by causing the
application to terminate unexpectedly.
