The remote Redhat Enterprise Linux 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2023:2870 advisory.

    FreeRADIUS is a high-performance and highly configurable free Remote Authentication Dial In User Service     (RADIUS) server, designed to allow centralized authentication and authorization for a network.

    Security Fix(es):

    * freeradius: Information leakage in EAP-PWD (CVE-2022-41859)

    * freeradius: Crash on unknown option in EAP-SIM (CVE-2022-41860)

    * freeradius: Crash on invalid abinary data (CVE-2022-41861)

    For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and     other related information, refer to the CVE page(s) listed in the References section.

    Additional Changes:

    For detailed information on changes in this release, see the Red Hat Enterprise Linux 8.8 Release Notes     linked from the References section.

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

The remote SUSE Linux SLES12 / SLES_SAP12 host has packages installed that are affected by multiple vulnerabilities as referenced in the SUSE-SU-2022:4621-1 advisory.

  - In freeradius, the EAP-PWD function compute_password_element() leaks information about the password which     allows an attacker to substantially reduce the size of an offline dictionary attack. (CVE-2022-41859)

  - In freeradius, when an EAP-SIM supplicant sends an unknown SIM option, the server will try to look that     option up in the internal dictionaries. This lookup will fail, but the SIM code will not check for that     failure. Instead, it will dereference a NULL pointer, and cause the server to crash. (CVE-2022-41860)

  - A flaw was found in freeradius. A malicious RADIUS client or home server can send a malformed abinary     attribute which can cause the server to crash. (CVE-2022-41861)

远程 Redhat Enterprise Linux 9 主机上安装的程序包受到 RHSA-2023: 2166 公告中提及的多个漏洞的影响。

  - 在 freeradius 中，EAP-PWD 函数 compute_password_element() 会泄漏有关密码的信息，攻击者因而能够大幅减小离线字典攻击的大小。(CVE-2022-41859)

  - 在 freeradius 中，如果 EAP-SIM 请求方发送未知的 SIM 选项，服务器则会尝试在内部字典中查找该选项。虽然查找失败，但 SIM 代码不会核查失败原因。相反，SIM 代码将取消引用空指针，并造成服务器崩溃。(CVE-2022-41860)

  - 在 freeradius 中发现一个缺陷。恶意的 RADIUS 客户端或主服务器可发送畸形的 abinary 属性，从而造成服务器崩溃。(CVE-2022-41861)

请注意，Nessus 尚未测试这些问题，而是只依据应用程序自我报告的版本号进行判断。

遠端 Debian 10 主機上安裝的多個套件受到 dla-3342 公告中提及的多個弱點影響。

  - 在 freeradius 中，EAP-PWD 函式 compute_password_element() 會洩漏有關密碼的資訊，進而允許攻擊者大幅減少離線字典攻擊的大小。(CVE-2022-41859)

  - 在 freeradius 中，當 EAP-SIM 要求者傳送未知的 SIM 選項時，伺服器將嘗試在內部字典中查閱該選項。此查閱作業將失敗，但 SIM 程式碼將不會檢查該失敗情況。相反，它會解除參照 NULL 指標，並造成伺服器當機。(CVE-2022-41860)

  - 在 freeradius 中發現一個瑕疵。惡意 RADIUS 用戶端或主伺服器可傳送格式錯誤的二進位屬性，進而造成伺服器當機。(CVE-2022-41861)

請注意，Nessus 並未測試這些問題，而是僅依據應用程式自我報告的版本號碼作出判斷。
