CVE-2016-6832
Heap-based buffer overflow in the ff_audio_resample function in resample.c in libav before 11.4 allows remote attackers to cause a denial of service (crash) via vectors related to buffer resizing.
Does this matter?
Lower severity and a low EPSS score (1.59%). Track it; it rarely justifies an emergency change on its own.
