CVE-2016-2194 is a vulnerability of currently unknown severity. The ressol function in Botan before 1.10.11 and 1.11.x before 1.11.27 allows remote attackers to cause a denial of service (infinite loop) via unspecified input to the OS2ECP function, related to a composite modulus.. EPSS estimates a 2.56% chance of exploitation in the next 30 days.
