According to the versions of the krb5 packages installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :

    In MIT Kerberos 5 (aka krb5) before 1.21.3, an attacker can modify the plaintext Extra Count field of a     confidential GSS krb5 wrap token, causing the unwrapped token to appear truncated to the     application.(CVE-2024-37370)

    In MIT Kerberos 5 (aka krb5) before 1.21.3, an attacker can cause invalid memory reads during GSS message     token handling by sending message tokens with invalid length fields.(CVE-2024-37371)
