Last modified

CVE-2016-2195 is a vulnerability of currently unknown severity. 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.. EPSS estimates a 6.68% chance of exploitation in the next 30 days.
