      * Kernel: NetLabel: null pointer dereference while receiving CIPSO packet with null category may cause     kernel panic (CVE-2020-10711)

Tenable has extracted the preceding description block directly from the MiracleLinux 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 :

  - btrfs_root_node in fs/btrfs/ctree.c in the Linux kernel     through 5.3.12 allows a NULL pointer dereference     because rcu_dereference(root->node) can be     zero.(CVE-2019-19036)

  - An issue was discovered in the Linux kernel before     5.0.6. In rx_queue_add_kobject() and     netdev_queue_add_kobject() in net/core/net-sysfs.c, a     reference count is mishandled, aka     CID-a3e23f719f5c.(CVE-2019-20811)

  - In calc_vm_may_flags of ashmem.c, there is a possible     arbitrary write to shared memory due to a permissions     bypass. This could lead to local escalation of     privilege by corrupting memory shared between     processes, with no additional execution privileges     needed. User interaction is not needed for     exploitation. Product: Android Versions: Android kernel     Android ID: A-142938932(CVE-2020-0009)

  - ** DISPUTED ** An issue was discovered in the Linux     kernel before 5.6. svm_cpu_uninit in arch/x86/kvm/svm.c     has a memory leak, aka CID-d80b64ff297e. NOTE: third     parties dispute this issue because it's a one-time leak     at the boot, the size is negligible, and it can't be     triggered at will.(CVE-2020-12768)

  - ** DISPUTED ** An issue was discovered in the Linux     kernel through 5.7.1. drivers/tty/vt/keyboard.c has an     integer overflow if k_ascii is called several times in     a row, aka CID-b86dab054059. NOTE: Members in the     community argue that the integer overflow does not lead     to a security issue in this case.(CVE-2020-13974)

  - In the Linux kernel through 5.7.6, usbtest_disconnect     in drivers/usb/misc/usbtest.c has a memory leak, aka     CID-28ebeb8db770.(CVE-2020-15393)

  - A NULL pointer dereference flaw was found in the Linux     kernel's SELinux subsystem in versions before 5.7. This     flaw occurs while importing the Commercial IP Security     Option (CIPSO) protocol's category bitmap into the     SELinux extensible bitmap via the'     ebitmap_netlbl_import' routine. While processing the     CIPSO restricted bitmap tag in the     'cipso_v4_parsetag_rbm' routine, it sets the security     attribute to indicate that the category bitmap is     present, even if it has not been allocated. This issue     leads to a NULL pointer dereference issue while     importing the same category bitmap into SELinux. This     flaw allows a remote network user to crash the system     kernel, resulting in a denial of service(     CVE-2020-10711)

  - A flaw was found in the Linux kernel's implementation     of Userspace core dumps. This flaw allows an attacker     with a local account to crash a trivial program and     exfiltrate private kernel data.(CVE-2020-10732)

  - A flaw was found in the Linux kernels SELinux LSM hook     implementation before version 5.7, where it incorrectly     assumed that an skb would only contain a single netlink     message. The hook would incorrectly only validate the     first netlink message in the skb and allow or deny the     rest of the messages within the skb with the granted     permission without further processing.(CVE-2020-10751)

  - A buffer over-read flaw was found in RH kernel versions     before 5.0 in crypto_authenc_extractkeys in     crypto/authenc.c in the IPsec Cryptographic algorithm's     module, authenc. When a payload longer than 4 bytes,     and is not following 4-byte alignment boundary     guidelines, it causes a buffer over-read threat,     leading to a system crash. This flaw allows a local     attacker with user privileges to cause a denial of     service.(CVE-2020-10769)

  - In the Linux kernel before 5.7.8, fs/nfsd/vfs.c (in the     NFS server) can set incorrect permissions on new     filesystem objects when the filesystem lacks ACL     support, aka CID-22cf8419f131. This occurs because the     current umask is not considered.(CVE-2020-24394)

  - The Linux kernel through 5.7.11 allows remote attackers     to make observations that help to obtain sensitive     information about the internal state of the network     RNG, aka CID-f227e3ec3b5c. This is related to     drivers/char/random.c and     kernel/time/timer.c.(CVE-2020-16166)

  - A flaw was found in the Linux kernel's implementation     of GRO in versions before 5.2. This flaw allows an     attacker with local access to crash the     system.(CVE-2020-10720)

  - In the Linux kernel through 5.8.7, local attackers able     to inject conntrack netlink configuration could     overflow a local buffer, causing crashes or triggering     use of incorrect protocol numbers in     ctnetlink_parse_tuple_filter in     net/netfilter/nf_conntrack_netlink.c, aka     CID-1cc5ef91d2ff.(CVE-2020-25211)

The version of AOS installed on the remote host is prior to 5.18. It is, therefore, affected by multiple vulnerabilities as referenced in the NXSA-AOS-5.18 advisory.

  - When using the Apache JServ Protocol (AJP), care must be taken when trusting incoming connections to     Apache Tomcat. Tomcat treats AJP connections as having higher trust than, for example, a similar HTTP     connection. If such connections are available to an attacker, they can be exploited in ways that may be     surprising. In Apache Tomcat 9.0.0.M1 to 9.0.0.30, 8.5.0 to 8.5.50 and 7.0.0 to 7.0.99, Tomcat shipped     with an AJP Connector enabled by default that listened on all configured IP addresses. It was expected     (and recommended in the security guide) that this Connector would be disabled if not required. This     vulnerability report identified a mechanism that allowed: - returning arbitrary files from anywhere in the     web application - processing any file in the web application as a JSP Further, if the web application     allowed file upload and stored those files within the web application (or the attacker was able to control     the content of the web application by some other means) then this, along with the ability to process a     file as a JSP, made remote code execution possible. It is important to note that mitigation is only     required if an AJP port is accessible to untrusted users. Users wishing to take a defence-in-depth     approach and block the vector that permits returning arbitrary files and execution as JSP may upgrade to     Apache Tomcat 9.0.31, 8.5.51 or 7.0.100 or later. A number of changes were made to the default AJP     Connector configuration in 9.0.31 to harden the default configuration. It is likely that users upgrading     to 9.0.31, 8.5.51 or 7.0.100 or later will need to make small changes to their configurations.
    (CVE-2020-1938)

  - rtl_p2p_noa_ie in drivers/net/wireless/realtek/rtlwifi/ps.c in the Linux kernel through 5.3.6 lacks a     certain upper-bound check, leading to a buffer overflow. (CVE-2019-17666)

  - The Linux kernel before 5.1-rc5 allows page->_refcount reference count overflow, with resultant use-after-     free issues, if about 140 GiB of RAM exists. This is related to fs/fuse/dev.c, fs/pipe.c, fs/splice.c,     include/linux/mm.h, include/linux/pipe_fs_i.h, kernel/trace/trace.c, mm/gup.c, and mm/hugetlb.c. It can     occur with FUSE requests. (CVE-2019-11487)

  - A flaw was found in the fix for CVE-2019-11135, in the Linux upstream kernel versions before 5.5 where,     the way Intel CPUs handle speculative execution of instructions when a TSX Asynchronous Abort (TAA) error     occurs. When a guest is running on a host CPU affected by the TAA flaw (TAA_NO=0), but is not affected by     the MDS issue (MDS_NO=1), the guest was to clear the affected buffers by using a VERW instruction     mechanism. But when the MDS_NO=1 bit was exported to the guests, the guests did not use the VERW mechanism     to clear the affected buffers. This issue affects guests running on Cascade Lake CPUs and requires that     host has 'TSX' enabled. Confidentiality of data is the highest threat associated with this vulnerability.
    (CVE-2019-19338)

  - The xz_decomp function in xzlib.c in libxml2 2.9.1 does not properly detect compression errors, which     allows context-dependent attackers to cause a denial of service (process hang) via crafted XML data.
    (CVE-2015-8035)

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

The SUSE Linux Enterprise 12 SP3 kernel was updated to receive various security and bugfixes.

The following security bugs were fixed :

CVE-2020-10135: Legacy pairing and secure-connections pairing authentication in Bluetooth may have allowed an unauthenticated user to complete authentication without pairing credentials via adjacent access. An unauthenticated, adjacent attacker could impersonate a Bluetooth BR/EDR master or slave to pair with a previously paired remote device to successfully complete the authentication procedure without knowing the link key (bnc#1171988).

CVE-2020-10711: A NULL pointer dereference flaw was found in the SELinux subsystem. This flaw occurs while importing the Commercial IP Security Option (CIPSO) protocol's category bitmap into the SELinux extensible bitmap via the' ebitmap_netlbl_import' routine. This flaw allowed a remote network user to crash the system kernel, resulting in a denial of service (bnc#1171191).

CVE-2020-10751: A flaw was found in the SELinux LSM hook implementation, where it incorrectly assumed that an skb would only contain a single netlink message.
