- CVE-2018-6767 (arbitrary code execution)

A stack-based buffer over-read in the ParseRiffHeaderConfig function of

denial-of-service attack or possibly have unspecified other impact via
a maliciously crafted RF64 file.

- CVE-2018-7253 (arbitrary code execution)

The ParseDsdiffHeaderConfig function of the cli/dsdiff.c file of

(heap-based buffer over-read) or possibly overwrite the heap via a
maliciously crafted DSDIFF file.

- CVE-2018-7254 (arbitrary code execution)

The ParseCaffHeaderConfig function of the cli/caff.c file of WavPack
5.1.0 allows a remote attacker to cause a denial-of-service (global

memory allocation, via a maliciously crafted CAF file.

Impact
======

A remote attacker is able to execute arbitrary code on the affected
host via maliciously crafted files.
