The remote Debian 11 host has packages installed that are affected by multiple vulnerabilities as referenced in the dsa-5287 advisory.

    Several vulnerabilities were discovered in Heimdal, an implementation of Kerberos 5 that aims to be     compatible with MIT Kerberos. CVE-2021-3671 Joseph Sutton discovered that the Heimdal KDC does not     validate that the server name in the TGS-REQ is present before dereferencing, which may result in denial     of service. CVE-2021-44758 It was discovered that Heimdal is prone to a NULL dereference in acceptors     where an initial SPNEGO token that has no acceptable mechanisms, which may result in denial of service for     a server application that uses SPNEGO. CVE-2022-3437 Several buffer overflow flaws and non-constant time     leaks were discovered when using 1DES, 3DES or RC4 (arcfour). CVE-2022-41916 An out-of-bounds memory     access was discovered when Heimdal normalizes Unicode, which may result in denial of service.
    CVE-2022-42898 It was discovered that integer overflows in PAC parsing may result in denial of service for     Heimdal KDCs or possibly Heimdal servers. CVE-2022-44640 It was discovered that the Heimdal's ASN.1     compiler generates code that allows specially crafted DER encodings to invoke an invalid free on the     decoded structure upon decode error, which may result in remote code execution in the Heimdal KDC. For the     stable distribution (bullseye), these problems have been fixed in version 7.7.0+dfsg-2+deb11u2. We     recommend that you upgrade your heimdal packages. For the detailed security status of heimdal please refer     to its security tracker page at: https://security-tracker.debian.org/tracker/heimdal

The remote SUSE Linux SLES12 / SLES_SAP12 host has packages installed that are affected by multiple vulnerabilities as referenced in the SUSE-SU-2023:0081-1 advisory.

  - A flaw was found in Samba. The security vulnerability occurs when KDC and the kpasswd service share a     single account and set of keys, allowing them to decrypt each other's tickets. A user who has been     requested to change their password, can exploit this flaw to obtain and use tickets to other services.
    (CVE-2022-2031)

  - A flaw was found in Samba. Some SMB1 write requests were not correctly range-checked to ensure the client     had sent enough data to fulfill the write, allowing server memory contents to be written into the file (or     printer) instead of client-supplied data. The client cannot control the area of the server memory written     to the file (or printer). (CVE-2022-32742)

  - A flaw was found in Samba. The KDC accepts kpasswd requests encrypted with any key known to it. By     encrypting forged kpasswd requests with its own key, a user can change other users' passwords, enabling     full domain takeover. (CVE-2022-32744)

  - A flaw was found in Samba. Samba AD users can cause the server to access uninitialized data with an LDAP     add or modify the request, usually resulting in a segmentation fault. (CVE-2022-32745)

  - A flaw was found in the Samba AD LDAP server. The AD DC database audit logging module can access LDAP     message values freed by a preceding database module, resulting in a use-after-free issue. This issue is     only possible when modifying certain privileged attributes, such as userAccountControl. (CVE-2022-32746)

  - A heap-based buffer overflow vulnerability was found in Samba within the GSSAPI unwrap_des() and     unwrap_des3() routines of Heimdal. The DES and Triple-DES decryption routines in the Heimdal GSSAPI     library allow a length-limited write buffer overflow on malloc() allocated memory when presented with a     maliciously small packet. This flaw allows a remote user to send specially crafted malicious data to the     application, possibly resulting in a denial of service (DoS) attack. (CVE-2022-3437)

  - Netlogon RPC Elevation of Privilege Vulnerability (CVE-2022-38023)

  - PAC parsing in MIT Kerberos 5 (aka krb5) before 1.19.4 and 1.20.x before 1.20.1 has integer overflows that     may lead to remote code execution (in KDC, kadmind, or a GSS or Kerberos application server) on 32-bit     platforms (which have a resultant heap-based buffer overflow), and cause a denial of service on other     platforms. This occurs in krb5_pac_parse in lib/krb5/krb/pac.c. Heimdal before 7.7.1 has a similar bug.

The remote SUSE Linux SUSE15 host has packages installed that are affected by multiple vulnerabilities as referenced in the openSUSE-SU-2023:0019-1 advisory.

  - All Samba versions 4.x.x before 4.9.17, 4.10.x before 4.10.11 and 4.11.x before 4.11.3 have an issue,     where the S4U (MS-SFU) Kerberos delegation model includes a feature allowing for a subset of clients to be     opted out of constrained delegation in any way, either S4U2Self or regular Kerberos authentication, by     forcing all tickets for these clients to be non-forwardable. In AD this is implemented by a user attribute     delegation_not_allowed (aka not-delegated), which translates to disallow-forwardable. However the Samba AD     DC does not do that for S4U2Self and does set the forwardable flag even if the impersonated client has the     not-delegated flag set. (CVE-2019-14870)

  - A null pointer de-reference was found in the way samba kerberos server handled missing sname in TGS-REQ     (Ticket Granting Server - Request). An authenticated user could use this flaw to crash the samba server.
    (CVE-2021-3671)

  - Heimdal before 7.7.1 allows attackers to cause a NULL pointer dereference in a SPNEGO acceptor via a     preferred_mech_type of GSS_C_NO_OID and a nonzero initial_response value to send_accept. (CVE-2021-44758)

  - A heap-based buffer overflow vulnerability was found in Samba within the GSSAPI unwrap_des() and     unwrap_des3() routines of Heimdal. The DES and Triple-DES decryption routines in the Heimdal GSSAPI     library allow a length-limited write buffer overflow on malloc() allocated memory when presented with a     maliciously small packet. This flaw allows a remote user to send specially crafted malicious data to the     application, possibly resulting in a denial of service (DoS) attack. (CVE-2022-3437)

  - Heimdal is an implementation of ASN.1/DER, PKIX, and Kerberos. Versions prior to 7.7.1 are vulnerable to a     denial of service vulnerability in Heimdal's PKI certificate validation library, affecting the KDC (via     PKINIT) and kinit (via PKINIT), as well as any third-party applications using Heimdal's libhx509. Users     should upgrade to Heimdal 7.7.1 or 7.8. There are no known workarounds for this issue. (CVE-2022-41916)

  - PAC parsing in MIT Kerberos 5 (aka krb5) before 1.19.4 and 1.20.x before 1.20.1 has integer overflows that     may lead to remote code execution (in KDC, kadmind, or a GSS or Kerberos application server) on 32-bit     platforms (which have a resultant heap-based buffer overflow), and cause a denial of service on other     platforms. This occurs in krb5_pac_parse in lib/krb5/krb/pac.c. Heimdal before 7.7.1 has a similar bug.
    (CVE-2022-42898)

  - Heimdal before 7.7.1 allows remote attackers to execute arbitrary code because of an invalid free in the     ASN.1 codec used by the Key Distribution Center (KDC). (CVE-2022-44640)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.
