Last modified

CVE-2015-8805 is a vulnerability of currently unknown severity. The ecc_256_modq function in ecc-256.c in Nettle before 3.2 does not properly handle carry propagation and produces incorrect output in its implementation of the P-256 NIST elliptic curve, which allows attackers to have unspecified impact via unknown vectors, a different vulnerability than CVE-2015-8803.. EPSS estimates a 2.74% chance of exploitation in the next 30 days.
