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

The Unity Linux 20 host has a package installed that is affected by a vulnerability as referenced in the UTSA-2026-003546 advisory.

    In the tun subsystem in the Linux kernel before 4.13.14, dev_get_valid_name is not called before     register_netdevice. This allows local users to cause a denial of service (NULL pointer dereference and     panic) via an ioctl(TUNSETIFF) call with a dev name containing a / character. This is similar to     CVE-2013-4343.

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

  - An integer overflow flaw was found in the way the Linux     kernel's networking subsystem processed TCP Selective     Acknowledgment (SACK) segments. While processing SACK     segments, the Linux kernel's socket buffer (SKB) data     structure becomes fragmented. Each fragment is about     TCP maximum segment size (MSS) bytes. To efficiently     process SACK blocks, the Linux kernel merges multiple     fragmented SKBs into one, potentially overflowing the     variable holding the number of segments. A remote     attacker could use this flaw to crash the Linux kernel     by sending a crafted sequence of SACK segments on a TCP     connection with small value of TCP MSS, resulting in a     denial of service (DoS). (CVE-2019-11477)

  - Kernel: tcp: excessive resource consumption while     processing SACK blocks allows remote denial of service     (CVE-2019-11478)

  - Kernel: tcp: excessive resource consumption for TCP     connections with low MSS allows remote denial of     service (CVE-2019-11479)

  - In the tun subsystem in the Linux kernel before     4.13.14, dev_get_valid_name is not called before     register_netdevice. This allows local users to cause a     denial of service (NULL pointer dereference and panic)     via an ioctl(TUNSETIFF) call with a dev name containing     a / character. This is similar to     CVE-2013-4343.(CVE-2018-7191)

  - A flaw was found in the Linux kernel where the coredump     implementation does not use locking or other mechanisms     to prevent vma layout or vma flags changes while it     runs. This allows local users to obtain sensitive     information, cause a denial of service (DoS), or     possibly have unspecified other impact by triggering a     race condition with mmget_not_zero or get_task_mm     calls.(CVE-2019-11599)

  - An issue was discovered in the Linux kernel before     4.20. There is a race condition in smp_task_timedout()     and smp_task_done() in     drivers/scsi/libsas/sas_expander.c, leading to a     use-after-free.(CVE-2018-20836)

  - A race condition in perf_event_open() allows local     attackers to leak sensitive data from setuid programs.
    As no relevant locks (in particular the     cred_guard_mutex) are held during the     ptrace_may_access() call, it is possible for the     specified target task to perform an execve() syscall     with setuid execution before perf_event_alloc()     actually attaches to it, allowing an attacker to bypass     the ptrace_may_access() check and the     perf_event_exit_task(current) call that is performed in     install_exec_creds() during privileged execve()     calls.(CVE-2019-3901)

  - A flaw was found in the Linux kernel, prior to version     5.0.7, in drivers/scsi/megaraid/megaraid_sas_base.c,     where a NULL pointer dereference can occur when     megasas_create_frame_pool() fails in     megasas_alloc_cmds(). An attacker can crash the system     if they were able to load the megaraid_sas kernel     module and groom memory beforehand, leading to a denial     of service (DoS), related to a     use-after-free.(CVE-2019-11810)

  - A vulnerability was found in polkit. When     authentication is performed by a non-root user to     perform an administrative task, the authentication is     temporarily cached in such a way that a local attacker     could impersonate the authorized process, thus gaining     access to elevated privileges.(CVE-2019-6133)

The remote Oracle Linux 6 / 7 host has packages installed that are affected by a vulnerability as referenced in the ELSA-2019-4703 advisory.

    kernel-uek     [3.8.13-118.36.1]
    - tun: call dev_get_valid_name() before register_netdevice() (Cong Wang)  [Orabug: 29925557]     {CVE-2018-7191}

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

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

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - In the tun subsystem in the Linux kernel before 4.13.14, dev_get_valid_name is not called before     register_netdevice. This allows local users to cause a denial of service (NULL pointer dereference and     panic) via an ioctl(TUNSETIFF) call with a dev name containing a / character. This is similar to     CVE-2013-4343. (CVE-2018-7191)

Note that Nessus relies on the presence of the package as reported by the vendor.

The version of AOS installed on the remote host is prior to 5.17.1. It is, therefore, affected by multiple vulnerabilities as referenced in the NXSA-AOS-5.17.1 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)
