Package : nettle
CVE ID : CVE-2021-3580 CVE-2021-20305
Debian Bug : 985652 989631

Multiple vulnerabilities were discovered in nettle, a low level
cryptographic library, which could result in denial of service (remote
crash in RSA decryption via specially crafted ciphertext, crash on ECDSA
signature verification) or incorrect verification of ECDSA signatures.

For the stable distribution (buster), these problems have been fixed in
version 3.4.1-1+deb10u1.

We recommend that you upgrade your nettle packages.

For the detailed security status of nettle please refer to
its security tracker page at:
