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.
