The remote SUSE Linux SUSE15 host has packages installed that are affected by multiple vulnerabilities as referenced in the openSUSE-SU-2021:1244-1 advisory.

  - An integer underflow issue exists in ntfs-3g 2017.3.23. A local attacker could potentially exploit this by     running /bin/ntfs-3g with specially crafted arguments from a specially crafted directory to cause a heap     buffer overflow, resulting in a crash or the ability to execute arbitrary code. In installations where     /bin/ntfs-3g is a setuid-root binary, this could lead to a local escalation of privileges. (CVE-2019-9755)

  - In NTFS-3G versions < 2021.8.22, when a specially crafted NTFS attribute is supplied to the function     ntfs_get_attribute_value, a heap buffer overflow can occur allowing for memory disclosure or denial of     service. The vulnerability is caused by an out-of-bound buffer access which can be triggered by mounting a     crafted ntfs partition. The root cause is a missing consistency check after reading an MFT record : the     bytes_in_use field should be less than the bytes_allocated field. When it is not, the parsing of the     records proceeds into the wild. (CVE-2021-33285)

    (CVE-2021-39262)

  - A crafted NTFS image can trigger a heap-based buffer overflow, caused by an unsanitized attribute in     ntfs_get_attribute_value, in NTFS-3G < 2021.8.22. (CVE-2021-39263)

  - A use-after-free flaw was found in libvirt. The qemuMonitorUnregister() function in     qemuProcessHandleMonitorEOF is called using multiple threads without being adequately protected by a     monitor lock. This flaw could be triggered by the virConnectGetAllDomainStats API when the guest is     shutting down. An unprivileged client with a read-only connection could use this flaw to perform a denial     of service attack by causing the libvirt daemon to crash. (CVE-2021-3975)

  - A NULL pointer dereference issue was found in the block mirror layer of QEMU in versions prior to 6.2.0.
    The `self` pointer is dereferenced in mirror_wait_on_conflicts() without ensuring that it's not NULL. A     malicious unprivileged user within the guest could use this flaw to crash the QEMU process on the host     when writing data reaches the threshold of mirroring node. (CVE-2021-4145)

  - A NULL pointer dereference issue was found in the ACPI code of QEMU. A malicious, privileged user within     the guest could use this flaw to crash the QEMU process on the host, resulting in a denial of service     condition. (CVE-2021-4158)

  - A flaw was found in the copying tool `nbdcopy` of libnbd. When performing multi-threaded copies using     asynchronous nbd calls, nbdcopy was blindly treating the completion of an asynchronous command as     successful, rather than checking the *error parameter. This could result in the silent creation of a     corrupted destination image. (CVE-2022-0485)

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

The version of AHV installed on the remote host is prior to 20230302.102005. It is, therefore, affected by multiple vulnerabilities as referenced in the NXSA-AHV-20230302.100173 advisory.

  - A crafted NTFS image can trigger a heap-based buffer overflow, caused by an unsanitized attribute in     ntfs_get_attribute_value, in NTFS-3G < 2021.8.22. (CVE-2021-39263)

  - EDK2's Network Package is susceptible to a buffer overflow vulnerability when processing DNS Servers     option from a DHCPv6 Advertise message. This vulnerability can be exploited by an attacker to gain     unauthorized access and potentially lead to a loss of Confidentiality, Integrity and/or Availability.
    (CVE-2023-45234)

  - A NULL pointer dereference was found In libssh during re-keying with algorithm guessing. This issue may     allow an authenticated client to cause a denial of service. (CVE-2023-1667)

  - A vulnerability was found in libssh, where the authentication check of the connecting client can be     bypassed in the`pki_verify_data_signature` function in memory allocation problems. This issue may happen     if there is insufficient memory or the memory usage is limited. The problem is caused by the return value     `rc,` which is initialized to SSH_ERROR and later rewritten to save the return value of the function call     `pki_key_check_hash_compatible.` The value of the variable is not changed between this point and the     cryptographic verification. Therefore any error between them calls `goto error` returning SSH_OK.
    (CVE-2023-2283)

  - A vulnerability was found that the response times to malformed ciphertexts in RSA-PSK ClientKeyExchange     differ from response times of ciphertexts with correct PKCS#1 v1.5 padding. (CVE-2023-5981)

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 ntfs-3g packages installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :

  - In NTFS-3G versions < 2021.8.22, when a specially crafted NTFS attribute is supplied to the function     ntfs_get_attribute_value, a heap buffer overflow can occur allowing for memory disclosure or denial of     service. The vulnerability is caused by an out-of-bound buffer access which can be triggered by mounting a     crafted ntfs partition. The root cause is a missing consistency check after reading an MFT record : the     'bytes_in_use' field should be less than the 'bytes_allocated' field. When it is not, the parsing of the     records proceeds into the wild. (CVE-2021-33285)

  - In NTFS-3G versions < 2021.8.22, when specially crafted NTFS attributes are read in the function     ntfs_attr_pread_i, a heap buffer overflow can occur and allow for writing to arbitrary memory or denial of     service of the application. (CVE-2021-33287)

  - In NTFS-3G versions < 2021.8.22, when a specially crafted MFT section is supplied in an NTFS image a heap     buffer overflow can occur and allow for code execution. (CVE-2021-33289)

  - In NTFS-3G versions < 2021.8.22, when a specially crafted NTFS inode pathname is supplied in an NTFS image     a heap buffer overflow can occur resulting in memory disclosure, denial of service and even code     execution. (CVE-2021-35266)

  - NTFS-3G versions < 2021.8.22, a stack buffer overflow can occur when correcting differences in the MFT and     MFTMirror allowing for code execution or escalation of privileges when setuid-root. (CVE-2021-35267)

  - In NTFS-3G versions < 2021.8.22, when a specially crafted NTFS inode is loaded in the function     ntfs_inode_real_open, a heap buffer overflow can occur allowing for code execution and escalation of     privileges. (CVE-2021-35268)

  - NTFS-3G versions < 2021.8.22, when a specially crafted NTFS attribute from the MFT is setup in the     function ntfs_attr_setup_flag, a heap buffer overflow can occur allowing for code execution and escalation     of privileges. (CVE-2021-35269)

  - A crafted NTFS image can cause a NULL pointer dereference in ntfs_extent_inode_open in NTFS-3G <     2021.8.22. (CVE-2021-39251)

  - A crafted NTFS image can cause an out-of-bounds read in ntfs_ie_lookup in NTFS-3G < 2021.8.22.
    (CVE-2021-39252)

  - A crafted NTFS image can cause an out-of-bounds read in ntfs_runlists_merge_i in NTFS-3G < 2021.8.22.
    (CVE-2021-39253)

  - A crafted NTFS image can cause an integer overflow in memmove, leading to a heap-based buffer overflow in     the function ntfs_attr_record_resize, in NTFS-3G < 2021.8.22. (CVE-2021-39254)

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

The version of AHV installed on the remote host is prior to 20230302.102005. It is, therefore, affected by multiple vulnerabilities as referenced in the NXSA-AHV-20230302.101026 advisory.

  - A crafted NTFS image can trigger a heap-based buffer overflow, caused by an unsanitized attribute in     ntfs_get_attribute_value, in NTFS-3G < 2021.8.22. (CVE-2021-39263)

  - EDK2's Network Package is susceptible to a buffer overflow vulnerability when processing DNS Servers     option from a DHCPv6 Advertise message. This vulnerability can be exploited by an attacker to gain     unauthorized access and potentially lead to a loss of Confidentiality, Integrity and/or Availability.
    (CVE-2023-45234)

  - Certain DNSSEC aspects of the DNS protocol (in RFC 4033, 4034, 4035, 6840, and related RFCs) allow remote     attackers to cause a denial of service (CPU consumption) via one or more DNSSEC responses, aka the     KeyTrap issue. One of the concerns is that, when there is a zone with many DNSKEY and RRSIG records, the     protocol specification implies that an algorithm must evaluate all combinations of DNSKEY and RRSIG     records. (CVE-2023-50387)

  - The Closest Encloser Proof aspect of the DNS protocol (in RFC 5155 when RFC 9276 guidance is skipped)     allows remote attackers to cause a denial of service (CPU consumption for SHA-1 computations) via DNSSEC     responses in a random subdomain attack, aka the NSEC3 issue. The RFC 5155 specification implies that an     algorithm must perform thousands of iterations of a hash function in certain situations. (CVE-2023-50868)

  - close_altfile in filename.c in less before 606 omits shell_quote calls for LESSCLOSE. (CVE-2022-48624)

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

Linux/Unix 主機上安裝了一個或多個受到弱點影響的套件，且供應商未提供可用的修補程式。

  - 在 NTFS-3G 2021.8.22 之前版本的 ntfs_runlists_merge_i 中使用建構的 NTFS 影像，可能會造成超出邊界讀取。
    (CVE-2021-39253)

請注意，Nessus 依賴供應商報告的套件存在。

遠端主機上安裝的 AHV 低於 20230302.102005 版。因此，它受到 NXSA-AHV-20230302.101026 公告中所提及的多個弱點影響。

  - 在 NTFS-3G 2021.8.22 之前版本中，特製的 NTFS 影像可觸發由 ntfs_get_attribute_value 中未清理的屬性所造成的堆積型緩衝區溢位弱點。(CVE-2021-39263)

  - EDK2 的 Network Package 在處理 DHCPv6 Advertise 訊息的 DNS Servers 選項時，容易受到緩衝區溢位弱點影響。攻擊者可利用此弱點來取得未經授權的存取權，並可能造成機密性、完整性和/或可用性喪失。
    (CVE-2023-45234)

  - 遠端攻擊者可利用 DNS 通訊協定 (在 RFC 4033、4034、4035、6840 和相關 RFC 中) 的特定 DNSSEC 方面，透過一或多個 DNSSEC 回應造成拒絕服務 (CPU 消耗)，即 KeyTrap 問題。其中一個問題是，當某個區域具有多個 DNSKEY 和 RRSIG 記錄時，通訊協定規格即表示演算法必須評估 DNSKEY 和 RRSIG 記錄的所有組合。(CVE-2023-50387)

  - 遠端攻擊者可利用 DNS 通訊協定 (略過 RFC 9276 指南時為 RFC 5155) 的最近封裝證明部分，透過隨機子網域攻擊中的 DNSSEC 回應造成拒絕服務 (SHA-1 計算的 CPU 消耗)，即 NSEC3 問題。RFC 5155 規格即表示，演算法必須在某些情況下執行雜湊函式的數千次反覆運算。(CVE-2023-50868)

  - 在 606 版之前的 less 中，filename.c 的 close_altfile 省略了對 LESSCLOSE 的 shell_quote 呼叫。(CVE-2022-48624)
