Description
This security bulletin contains information about 2 vulnerabilities.
1) Observable discrepancy (CVE-ID: CVE-2023-50782)
CWE-ID: CWE-203 - Observable 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 potentially sensitive information.
The vulnerability exists due to excessive data output by the application. A remote attacker can decrypt captured messages in TLS servers that use RSA key exchanges, which may lead to exposure of confidential or sensitive data.
2) Resource exhaustion (CVE-ID: CVE-2024-41996)
CWE-ID: CWE-400 - Resource exhaustion
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Green
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to unnecessary validation of the public keys in the Diffie-Hellman Key Agreement Protocol when an approved safe prime is used. A remote attacker from the client side can trigger unnecessarily expensive server-side DHE modular-exponentiation calculations and cause asymmetric resource consumption, resulting in a denial of service (DoS) attack.
