The manipulation with an unknown input leads to a memory corruption vulnerability. CWE is classifying the issue as CWE-119. The product performs operations on a memory buffer, but it can read from or write to a memory location that is outside of the intended boundary of the buffer. This is going to have an impact on confidentiality, integrity, and availability. CVE summarizes:

Buffer overflow in APNGDis 2.8 and earlier allows a remote attackers to cause denial of service and possibly execute arbitrary code via a crafted image containing a malformed chunk size descriptor.

The bug was discovered 03/14/2017. The weakness was disclosed 02/20/2018 as EDB-ID 41668 as confirmed exploit (Exploit-DB). The advisory is available at exploit-db.com. This vulnerability is traded as CVE-2017-6192 since 02/22/2017. It is possible to launch the attack remotely. The exploitation doesn't require any form of authentication. Technical details are unknown but a public exploit is available.

A public exploit has been developed by Alwin Peppels and been published before and not just after the advisory. The exploit is shared for download at exploit-db.com. It is declared as proof-of-concept. The vulnerability was handled as a non-public zero-day exploit for at least 343 days. During that time the estimated underground price was around $0-$5k.

There is no information about possible countermeasures known. It may be suggested to replace the affected object with an alternative product.
