The remote SUSE Linux SLES11 / SLES_SAP11 host has packages installed that are affected by multiple vulnerabilities as referenced in the SUSE-SU-2021:14764-1 advisory.

    The SUSE Linux Enterprise 11 SP4 kernel was updated to receive various security and bugfixes.


    The following security bugs were fixed:

    - CVE-2021-0512: Fixed a possible out of bounds write due to a heap buffer overflow in
    __hidinput_change_resolution_multipliers. This could lead to local escalation of privilege with no     additional execution privileges needed. User interaction is not needed for exploitation. (bsc#1187595)
    - CVE-2021-34693: Fixed a bug in net/can/bcm.c which could allow local users to obtain sensitive     information from kernel stack memory because parts of a data structure are uninitialized. (bsc#1187452)
    - CVE-2020-36386: Fixed an out-of-bounds read in hci_extended_inquiry_result_evt. (bsc#1187038)
    - CVE-2020-24588: Fixed a bug that could allow an adversary to abuse devices that support receiving non-     SSP A-MSDU frames to inject arbitrary network packets. (bsc#1185861 bsc#1185863)
    - CVE-2021-29154: Fixed an incorrect computation of branch displacements in the BPF JIT compilers, which     could allow to execute arbitrary code within the kernel context. (bsc#1184391)
    - CVE-2021-32399: Fixed a race condition in net/bluetooth/hci_request.c for removal of the HCI controller.
    (bsc#1184611)

    The firmware-nonfree package has been updated to include addtional firmware     that may be requested by some drivers in Linux 5.10, availble for Debian LTS as     backported kernel.

    Some of the updated firmware files adresses security vulnerabilities, which may     allow Escalation of Privileges, Denial of Services and Information Disclosures.

    CVE-2020-24586 (INTEL-SA-00473)

        The 802.11 standard that underpins Wi-Fi Protected Access (WPA,         WPA2, and WPA3) and Wired Equivalent Privacy (WEP) doesn't require         that received fragments be cleared from memory after (re)connecting         to a network. Under the right circumstances, when another device         sends fragmented frames encrypted using WEP, CCMP, or GCMP, this can         be abused to inject arbitrary network packets and/or exfiltrate user         data.

    CVE-2020-24587  (INTEL-SA-00473)

        The 802.11 standard that underpins Wi-Fi Protected Access (WPA,         WPA2, and WPA3) and Wired Equivalent Privacy (WEP) doesn't require         that all fragments of a frame are encrypted under the same key. An         adversary can abuse this to decrypt selected fragments when another         device sends fragmented frames and the WEP, CCMP, or GCMP encryption         key is periodically renewed.

    CVE-2020-24588  (INTEL-SA-00473)

        The 802.11 standard that underpins Wi-Fi Protected Access (WPA,         WPA2, and WPA3) and Wired Equivalent Privacy (WEP) doesn't require         that the A-MSDU flag in the plaintext QoS header field is         authenticated. Against devices that support receiving non-SSP A-MSDU         frames (which is mandatory as part of 802.11n), an adversary can         abuse this to inject arbitrary network packets.

    CVE-2021-23168  (INTEL-SA-00621)

        Out of bounds read for some Intel(R) PROSet/Wireless WiFi and         Killer(TM) WiFi products may allow an unauthenticated user to         potentially enable denial of service via adjacent access.

    CVE-2021-23223 (INTEL-SA-00621)

        Improper initialization for some Intel(R) PROSet/Wireless WiFi and         Killer(TM) WiFi products may allow a privileged user to potentially         enable escalation of privilege via local access.

    CVE-2021-37409 (INTEL-SA-00621)

        Improper access control for some Intel(R) PROSet/Wireless WiFi and         Killer(TM) WiFi products may allow a privileged user to potentially         enable escalation of privilege via local access.

    CVE-2021-44545 (INTEL-SA-00621)

        Improper input validation for some Intel(R) PROSet/Wireless WiFi and         Killer(TM) WiFi products may allow an unauthenticated user to         potentially enable denial of service via adjacent access.

    CVE-2022-21181 (INTEL-SA-00621)

        Improper input validation for some Intel(R) PROSet/Wireless WiFi and         Killer(TM) WiFi products may allow a privileged user to potentially         enable escalation of privilege via local access.

    The following advisories are also fixed by this upload, but needs an     updated Linux kernel to load the updated firmware:

    CVE-2020-12362 (INTEL-SA-00438)

        Integer overflow in the firmware for some Intel(R) Graphics Drivers         for Windows * before version 26.20.100.7212 and before Linux kernel         version 5.5 may allow a privileged user to potentially enable an         escalation of privilege via local access.

    CVE-2020-12363 (INTEL-SA-00438)

        Improper input validation in some Intel(R) Graphics Drivers for         Windows* before version 26.20.100.7212 and before Linux kernel         version 5.5 may allow a privileged user to potentially enable a         denial of service via local access.

    CVE-2020-12364 (INTEL-SA-00438)

        Null pointer reference in some Intel(R) Graphics Drivers for         Windows* before version 26.20.100.7212 and before version Linux         kernel version 5.5 may allow a privileged user to potentially enable         a denial of service via local access.

Tenable has extracted the preceding description block directly from the SUSE security advisory.

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

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

  - The 802.11 standard that underpins Wi-Fi Protected Access (WPA, WPA2, and WPA3) and Wired Equivalent     Privacy (WEP) doesn't require that received fragments be cleared from memory after (re)connecting to a     network. Under the right circumstances, when another device sends fragmented frames encrypted using WEP,     CCMP, or GCMP, this can be abused to inject arbitrary network packets and/or exfiltrate user data.
    (CVE-2020-24586)

  - The 802.11 standard that underpins Wi-Fi Protected Access (WPA, WPA2, and WPA3) and Wired Equivalent     Privacy (WEP) doesn't require that all fragments of a frame are encrypted under the same key. An adversary     can abuse this to decrypt selected fragments when another device sends fragmented frames and the WEP,     CCMP, or GCMP encryption key is periodically renewed. (CVE-2020-24587)

  - The 802.11 standard that underpins Wi-Fi Protected Access (WPA, WPA2, and WPA3) and Wired Equivalent     Privacy (WEP) doesn't require that the A-MSDU flag in the plaintext QoS header field is authenticated.
    Against devices that support receiving non-SSP A-MSDU frames (which is mandatory as part of 802.11n), an     adversary can abuse this to inject arbitrary network packets. (CVE-2020-24588)

  - An issue was discovered in the kernel in NetBSD 7.1. An Access Point (AP) forwards EAPOL frames to other     clients even though the sender has not yet successfully authenticated to the AP. This might be abused in     projected Wi-Fi networks to launch denial-of-service attacks against connected clients and makes it easier     to exploit other vulnerabilities in connected clients. (CVE-2020-26139)

  - An issue was discovered in the ALFA Windows 10 driver 6.1316.1209 for AWUS036H. The WEP, WPA, WPA2, and     WPA3 implementations accept plaintext frames in a protected Wi-Fi network. An adversary can abuse this to     inject arbitrary data frames independent of the network configuration. (CVE-2020-26140)

  - An issue was discovered in the ALFA Windows 10 driver 6.1316.1209 for AWUS036H. The Wi-Fi implementation     does not verify the Message Integrity Check (authenticity) of fragmented TKIP frames. An adversary can     abuse this to inject and possibly decrypt packets in WPA or WPA2 networks that support the TKIP data-     confidentiality protocol. (CVE-2020-26141)

  - An issue was discovered in the kernel in OpenBSD 6.6. The WEP, WPA, WPA2, and WPA3 implementations treat     fragmented frames as full frames. An adversary can abuse this to inject arbitrary network packets,     independent of the network configuration. (CVE-2020-26142)

  - An issue was discovered in the ALFA Windows 10 driver 1030.36.604 for AWUS036ACH. The WEP, WPA, WPA2, and     WPA3 implementations accept fragmented plaintext frames in a protected Wi-Fi network. An adversary can     abuse this to inject arbitrary data frames independent of the network configuration. (CVE-2020-26143)

  - A flaw was found in the Linux kernel, where the WiFi implementations accept plaintext A-MSDU frames as     long as the first 8 bytes correspond to a valid RFC1042 (ex., LLC/SNAP) header for EAPOL. The highest     threat from this vulnerability is to integrity. (CVE-2020-26144)

  - An issue was discovered on Samsung Galaxy S3 i9305 4.4.4 devices. The WEP, WPA, WPA2, and WPA3     implementations accept second (or subsequent) broadcast fragments even when sent in plaintext and process     them as full unfragmented frames. An adversary can abuse this to inject arbitrary network packets     independent of the network configuration. (CVE-2020-26145)

  - A vulnerability was found in Linux kernel, where the WiFi implementation reassemble fragments with non-     consecutive packet numbers. An adversary can abuse this to exfiltrate selected fragments. This     vulnerability is exploitable when another device sends fragmented frames and the WEP, CCMP, or GCMP data-     confidentiality protocol is used. Note that WEP is vulnerable to this attack by design. (CVE-2020-26146)

  - An issue was discovered in the Linux kernel 5.8.9. The WEP, WPA, WPA2, and WPA3 implementations reassemble     fragments even though some of them were sent in plaintext. This vulnerability can be abused to inject     packets and/or exfiltrate selected fragments when another device sends fragmented frames and the WEP,     CCMP, or GCMP data-confidentiality protocol is used. (CVE-2020-26147)

  - In unix_scm_to_skb of af_unix.c, there is a possible use after free bug due to a race condition. This     could lead to local escalation of privilege with System execution privileges needed.
