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.

A flaw was found in the way nettle's RSA decryption functions handled specially crafted ciphertext. An attacker could use this flaw to provide a manipulated ciphertext leading to application crash and denial of service.
