    Package        : openssl
    CVE ID         : CVE-2019-1543
    
    Joran Dirk Greef discovered that overly long nonces used with
    ChaCha20-Poly1305 were incorrectly processed and could result in nonce
    reuse. This doesn't affect OpenSSL-internal uses of ChaCha20-Poly1305
    such as TLS.
    
    For the stable distribution (stretch), this problem has been fixed in
    version 1.1.0k-1~deb9u1. This DSA also upgrades openssl1.0 (which
    itself is not affected by CVE-2019-1543) to 1.0.2s-1~deb9u1
    
    We recommend that you upgrade your openssl packages.
    
    For the detailed security status of openssl please refer to
    its security tracker page at:
