The remote MiracleLinux 4 host has packages installed that are affected by multiple vulnerabilities as referenced in the AXSA:2013-540:05 advisory.

    The kernel package contains the Linux kernel (vmlinuz), the core of any Linux operating system. The kernel     handles the basic functions of the operating system: memory allocation, process allocation, device input     and output, etc.
    Security issues fixed with this release:
     CVE-2013-1935      A certain Red Hat patch to the KVM subsystem in the kernel package before 2.6.32-358.11.1.el6 on Red Hat     Enterprise Linux (RHEL) 6 does not properly implement the PV EOI feature, which allows guest OS users to     cause a denial of service (host OS crash) by leveraging a time window during which interrupts are disabled     but copy_to_user function calls are possible.
     CVE-2013-1943      The KVM subsystem in the Linux kernel before 3.0 does not check whether kernel addresses are specified     during allocation of memory slots for use in a guest's physical address space, which allows local users to     gain privileges or obtain sensitive information from kernel memory via a crafted application, related to     arch/x86/kvm/paging_tmpl.h and virt/kvm/kvm_main.c.
     CVE-2013-2017     The veth (aka virtual Ethernet) driver in the Linux kernel before 2.6.34 does not properly manage skbs     during congestion, which allows remote attackers to cause a denial of service (system crash) by leveraging     lack of skb consumption in conjunction with a double-free error.

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.

The Unity Linux 20 host has a package installed that is affected by a vulnerability as referenced in the UTSA-2026-000977 advisory.

The remote Redhat Enterprise Linux 6 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2013:0911 advisory.

    The kernel packages contain the Linux kernel, the core of any Linux     operating system.

    This update fixes the following security issues:

    * A flaw was found in the way KVM (Kernel-based Virtual Machine)     initialized a guest's registered pv_eoi (paravirtualized end-of-interrupt)     indication flag when entering the guest. An unprivileged guest user could     potentially use this flaw to crash the host. (CVE-2013-1935, Important)

    * A missing sanity check was found in the kvm_set_memory_region() function     in KVM, allowing a user-space process to register memory regions pointing     to the kernel address space. A local, unprivileged user could use this flaw     to escalate their privileges. (CVE-2013-1943, Important)

    * A double free flaw was found in the Linux kernel's Virtual Ethernet     Tunnel driver (veth). A remote attacker could possibly use this flaw to     crash a target system. (CVE-2013-2017, Moderate)

    Red Hat would like to thank IBM for reporting the CVE-2013-1935 issue and     Atzm WATANABE of Stratosphere Inc. for reporting the CVE-2013-2017 issue.
    The CVE-2013-1943 issue was discovered by Michael S. Tsirkin of Red Hat.

    This update also fixes several bugs and adds one enhancement. Documentation     for these changes will be available shortly from the Technical Notes     document linked to in the References section.

    Users should upgrade to these updated packages, which contain backported     patches to correct these issues and add this enhancement. The system must     be rebooted for this update to take effect.
