CVEID: CVE-2019-17023
DESCRIPTION: Mozilla Firefox could allow a remote attacker to bypass security restrictions, caused by the negotiaition of a lower protocol after a HelloRetryRequest is sent. By persuading a victim to visit a specially-crafted Web site, a remote attacker could exploit this vulnerability to trigger an invalid state transition in the TLS State Machine to ignore incoming Application Data records.
CVSS Base score: 6.5
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/174062 for the current score.

CVEID: CVE-2020-12403
DESCRIPTION: Mozilla Network Security Services (NSS), as used in Mozilla Firefox could allow a remote attacker to obtain sensitive information, caused by the implementation of CHACHA20-POLY1305 decryption with undersized tag. By persuading a victim to visit a specially-crafted Web site, a remote attacker could exploit this vulnerability using multi-part Chacha20 to trigger an out-of-bounds read and obtain sensitive information.
CVSS Base score: 6.8
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/187746 for the current score.
