Security Bulletin

This security bulletin contains information about 5 vulnerabilities.

1) Improper Encoding or Escaping of Output

EUVDB-ID: #VU118183

Risk: Low

CVSSv4.0: 0.5 [CVSS:4.0/AV:N/AC:H/AT:N/PR:N/UI:A/VC:N/VI:L/VA:N/SC:N/SI:N/SA:N/E:U/U:Clear]

CVE-ID: CVE-2025-58189

CWE-ID: CWE-116 - Improper Encoding or Escaping of Output

Exploit availability: No

Description

The vulnerability allows a remote attacker to perform spoofing attacks.

The vulnerability exists due to missing sanitization of input data when the Conn.Handshake fails during ALPN negotiation in crypto/tls. A remote attacker can pass specially crafted input via an error message and influence the application behavior, leading to a potential spoofing attack. 

Mitigation

Install updates from vendor's repository.

Vulnerable software versions

Fedora: 43

docker-buildx: before 0.30.0-1.fc43

CPE2.3 External links

https://bodhi.fedoraproject.org/updates/FEDORA-2025-36ed57480f


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: #VU118184

Risk: Medium

CVSSv4.0: 6.6 [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]

CVE-ID: CVE-2025-61723

CWE-ID: CWE-400 - Resource exhaustion
