The Unity Linux 20 host has a package installed that is affected by a vulnerability as referenced in the UTSA-2026-000803 advisory.

    The sctp_process_param function in net/sctp/sm_make_chunk.c in the SCTP implementation in the Linux kernel     before 3.17.4, when ASCONF is used, allows remote attackers to cause a denial of service (NULL pointer     dereference and system crash) via a malformed INIT chunk.

Tenable has extracted the preceding description block directly from the Unity 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 remote Redhat Enterprise Linux 7 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2015:0102 advisory.

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

    * A flaw was found in the way the Linux kernel's SCTP implementation     validated INIT chunks when performing Address Configuration Change     (ASCONF). A remote attacker could use this flaw to crash the system by     sending a specially crafted SCTP packet to trigger a NULL pointer     dereference on the system. (CVE-2014-7841, Important)

    * A race condition flaw was found in the way the Linux kernel's mmap(2),     madvise(2), and fallocate(2) system calls interacted with each other while     operating on virtual memory file system files. A local user could use this     flaw to cause a denial of service. (CVE-2014-4171, Moderate)

    * A NULL pointer dereference flaw was found in the way the Linux kernel's     Common Internet File System (CIFS) implementation handled mounting of file     system shares. A remote attacker could use this flaw to crash a client     system that would mount a file system share from a malicious server.
    (CVE-2014-7145, Moderate)

    * A flaw was found in the way the Linux kernel's splice() system call     validated its parameters. On certain file systems, a local, unprivileged     user could use this flaw to write past the maximum file size, and thus     crash the system. (CVE-2014-7822, Moderate)

    * It was found that the parse_rock_ridge_inode_internal() function of the     Linux kernel's ISOFS implementation did not correctly check relocated     directories when processing Rock Ridge child link (CL) tags. An attacker     with physical access to the system could use a specially crafted ISO image     to crash the system or, potentially, escalate their privileges on the     system. (CVE-2014-5471, CVE-2014-5472, Low)

    Red Hat would like to thank Akira Fujita of NEC for reporting the     CVE-2014-7822 issue. The CVE-2014-7841 issue was discovered by Liu Wei of     Red Hat.

    This update also fixes the following bugs:

    * Previously, a kernel panic could occur if a process reading from a locked     NFS file was killed and the lock was not released properly before the read     operations finished. Consequently, the system crashed. The code handling     file locks has been fixed, and instead of halting, the system now emits a     warning about the unreleased lock. (BZ#1172266)

    * A race condition in the command abort handling logic of the ipr device     driver could cause the kernel to panic when the driver received a response     to an abort command prior to receiving other responses to the aborted     command due to the support for multiple interrupts. With this update, the     abort handler waits for the aborted command's responses first before     completing an abort operation. (BZ#1162734)

    * Previously, a race condition could occur when changing a Page Table Entry     (PTE) or a Page Middle Directory (PMD) to pte_numa or pmd_numa,     respectively, causing the kernel to crash. This update removes the BUG_ON()     macro from the __handle_mm_fault() function, preventing the kernel panic in     the aforementioned scenario. (BZ#1170662)

    All kernel users are advised to upgrade to these updated packages, which     contain backported patches to correct these issues. The system must be     rebooted for this update to take effect.

* An integer overflow flaw was found in the way the Linux kernel's Advanced Linux Sound Architecture (ALSA) implementation handled user controls. A local, privileged user could use this flaw to crash the system. (CVE-2014-4656, Moderate)

The system must be rebooted for this update to take effect.

Updated kernel packages that fix one security issue and three bugs are now available for Red Hat Enterprise Linux 6.4 Extended Update Support.

Red Hat Product Security has rated this update as having Important security impact. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available from the CVE link in the References section.

This issue was discovered by Liu Wei of Red Hat.

This update also fixes the following bugs :

* Due to several bugs in the network console logging, a race condition between the network console send operation and the driver's IRQ handler could occur, or the network console could access invalid memory content. As a consequence, the respective driver, such as vmxnet3, triggered a BUG_ON() assertion and the system terminated unexpectedly. A patch addressing these bugs has been applied so that driver's IRQs are disabled before processing the send operation and the network console now accesses the RCU-protected (read-copy update) data properly. Systems using the network console logging no longer crashes due to the aforementioned conditions. (BZ#1165983)

* A bug in the vmxnet3 driver allowed potential race conditions to be triggered when the driver was used with the netconsole module. The race conditions allowed the driver's internal New API (NAPI) poll routine to run concurrently with the netpoll controller routine, which resulted in data corruption and a subsequent kernel panic. To fix this problem, the vmxnet3 driver has been modified to call the appropriate interrupt handler to schedule NAPI poll requests properly.
(BZ#1179594)

* Prior to this update, nfs_mark_return_delegation() was called without any locking, resulting in unsafe dereferencing of delegation->inode. Because the inode is only used to discover the nfs_client, the callers now pass a valid pointer to the nfs_server as a parameter. (BZ#1187637)

All kernel users are advised to upgrade to these updated packages, which contain backported patches to correct these issues. The system must be rebooted for this update to take effect.

The SUSE Linux Enterprise 12 kernel was updated to 3.12.31 to receive various security and bugfixes.

Security issues fixed: CVE-2014-9322: A local privilege escalation in the x86_64 32bit compatibility signal handling was fixed, which could be used by local attackers to crash the machine or execute code.

  - CVE-2014-9090: Various issues in LDT handling in 32bit     compatibility mode on the x86_64 platform were fixed,     where local attackers could crash the machine.

  - CVE-2014-8133: Insufficient validation of TLS register     usage could leak information from the kernel stack to     userspace.

  - CVE-2014-7826: kernel/trace/trace_syscalls.c in the     Linux kernel did not properly handle private syscall     numbers during use of the ftrace subsystem, which     allowed local users to gain privileges or cause a denial     of service (invalid pointer dereference) via a crafted     application.

  - CVE-2014-3647: Nadav Amit reported that the KVM (Kernel     Virtual Machine) mishandled noncanonical addresses when     emulating instructions that change the rip (Instruction     Pointer). A guest user with access to I/O or the MMIO     could use this flaw to cause a denial of service (system     crash) of the guest.

  - CVE-2014-3611: A race condition flaw was found in the     way the Linux kernel's KVM subsystem handled PIT     (Programmable Interval Timer) emulation. A guest user     who has access to the PIT I/O ports could use this flaw     to crash the host.

  - CVE-2014-3610: If the guest writes a noncanonical value     to certain MSR registers, KVM will write that value to     the MSR in the host context and a #GP will be raised     leading to kernel panic. A privileged guest user could     have used this flaw to crash the host.

  - CVE-2014-7841: A remote attacker could have used a flaw     in SCTP to crash the system by sending a maliciously     prepared SCTP packet in order to trigger a NULL pointer     dereference on the server.

  - CVE-2014-3673: The SCTP implementation in the Linux     kernel allowed remote attackers to cause a denial of     service (system crash) via a malformed ASCONF chunk,     related to net/sctp/sm_make_chunk.c and     net/sctp/sm_statefuns.c.

  - CVE-2014-3185: Multiple buffer overflows in the     command_port_read_callback function in     drivers/usb/serial/whiteheat.c in the Whiteheat USB     Serial Driver in the Linux kernel allowed physically     proximate attackers to execute arbitrary code or cause a     denial of service (memory corruption and system crash)     via a crafted device that provides a large amount of (1)     EHCI or (2) XHCI data associated with a bulk response.

Note that Tenable Network Security has extracted the preceding description block directly from the SUSE security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

The openSUSE 13.1 kernel was updated to fix security issues and bugs :

Security issues fixed: CVE-2014-9322: A local privilege escalation in the x86_64 32bit compatibility signal handling was fixed, which could be used by local attackers to crash the machine or execute code.

CVE-2014-9090: The do_double_fault function in arch/x86/kernel/traps.c in the Linux kernel did not properly handle faults associated with the Stack Segment (SS) segment register, which allowed local users to cause a denial of service (panic) via a modify_ldt system call, as demonstrated by sigreturn_32 in the linux-clock-tests test suite.
