Nettle is a low-level encryption library.

In versions earlier than Nettle 3.2, the ecc_256_modq function in the ecc-256.c does not properly handle carry forward, and an incorrect output occurs in the implementation of the NIST elliptic curve in the P-256, which allows attackers to exploit this vulnerability to perform security attacks.
