Description

This security bulletin contains information about 1 vulnerability.


1) Return of Wrong Status Code (CVE-ID: CVE-2025-5987)

CWE-ID: CWE-393 - Return of Wrong Status Code

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


The vulnerability allows a remote attacker to compromise the affected system.

The vulnerability exists due to incorrect handling of the wrong status code returned by the OpenSSL within the chacha20_poly1305_set_key() function when using the ChaCha20 cipher with the OpenSSL library. A remote attacker can force the library to partially initialize cipher context, leading to an undefined application's behavior.
