Security Bulletin

This security bulletin contains information about 2 vulnerabilities.

1) Observable discrepancy

EUVDB-ID: #VU88199

Risk: Medium

CVSSv3.1: 6.5 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N/E:U/RL:O/RC:C]

CVE-ID: CVE-2023-50782

CWE-ID: CWE-203 - Observable discrepancy

Exploit availability: No

Description

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.

Mitigation

Update the affected package openssl-3 to the latest version.

Vulnerable software versions

Q & A

Can this vulnerability be exploited remotely?

Yes. This vulnerability can be exploited by a remote non-authenticated attacker via the Internet.

Is there known malware, which exploits this vulnerability?

No. We are not aware of malware exploiting this vulnerability.

2) Resource exhaustion

EUVDB-ID: #VU98050

Risk: Medium

CVSSv3.1: 6.5 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H/E:U/RL:O/RC:C]

CVE-ID: CVE-2024-41996

CWE-ID: CWE-400 - Resource exhaustion

Exploit availability: No

Description

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.

Mitigation

Update the affected package openssl-3 to the latest version.
