CVE-2016-2195
Integer overflow in the PointGFp constructor in Botan before 1.10.11 and 1.11.x before 1.11.27 allows remote attackers to overwrite memory and possibly execute arbitrary code via a crafted ECC point, which triggers a heap-based buffer overflow.

Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (6.68%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
