Vulnerability Details

CVEID: CVE-2019-1543 DESCRIPTION: OpenSSL could allow a remote attacker to obtain sensitive information, caused by an error in the ChaCha20-Poly1305 AEAD cipher. By sending a message encrypted using a reused overly long nonce, an attacker could exploit this vulnerability to conduct serious confidentiality and integrity attacks.
CVSS Base Score: 4.8

CVEID: CVE-2019-9517 DESCRIPTION: Multiple vendors are vulnerable to a denial of service, caused by an Internal Data Buffering attack. By opening the HTTP/2 window so the peer can send without constraint and sending a stream of requests for a large response object, a remote attacker could consume excessive CPU resources.
