CWE-310  (opens in a new tab)
CWE-254  (opens in a new tab)

How to fix?

Upgrade Debian:9 nettle to version 3.2-1 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream nettle package and not the nettle package as distributed by Debian. See How to fix? for Debian:9 relevant fixed versions and status.

The ecc_256_modp 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-2015-8805.
