Description

This security bulletin contains information about 2 vulnerabilities.

1) Missing Required Cryptographic Step (CVE-ID: CVE-2019-3738)

CWE-ID: CWE-325 - Missing Required Cryptographic Step

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N/E:U/U:Green

The vulnerability allows a remote attacker to gain access to sensitive information.

The vulnerability exists due to an error in the cryptographic process. A remote attacker can coerce two parties into computing the same predictable shared key and gain access to sensitive information.

2) Information Exposure Through Timing Discrepancy (CVE-ID: CVE-2019-3739)

CWE-ID: CWE-208 - Information Exposure Through Timing Discrepancy

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N/E:U/U:Green

The vulnerability allows a remote attacker to gain access to sensitive information.

The vulnerability exists due to a timing discrepancy during ECDSA key generation. A remote attacker can recover the ECDSA keys and decrypt encrypted information.
