The remote Redhat Enterprise Linux 7 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2024:5316 advisory.

    Kerberos is a network authentication system, which can improve the security of your network by eliminating     the insecure practice of sending passwords over the network in unencrypted form. It allows clients and     servers to authenticate to each other with the help of a trusted third party, the Kerberos key     distribution center (KDC).

    Package        : krb5     CVE ID         : CVE-2024-37370 CVE-2024-37371

    Two vulnerabilities were discovered in the GSS message token handling in     krb5, the MIT implementation of Kerberos. An attacker can take advantage     of these flaws to bypass integrity protections or cause a denial of     service.

    For the oldstable distribution (bullseye), these problems have been fixed     in version 1.18.3-6+deb11u5.

    For the stable distribution (bookworm), these problems have been fixed in     version 1.20.1-2+deb12u2.

    We recommend that you upgrade your krb5 packages.

    For the detailed security status of krb5 please refer to its security     tracker page at:
    https://security-tracker.debian.org/tracker/krb5
