The Unity Linux 20 host has a package installed that is affected by a vulnerability as referenced in the UTSA-2026-002332 advisory.

    fs/btrfs/inode.c in the Linux kernel before 4.3.3 mishandles compressed inline extents, which allows local     users to obtain sensitive pre-truncation information from a file via a clone action.

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 Oracle Linux 7 host has packages installed that are affected by multiple vulnerabilities as referenced in the ELSA-2016-2574 advisory.

An update for kernel is now available for Red Hat Enterprise Linux 7.

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

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

Security Fix(es) :

* It was found that the Linux kernel's IPv6 implementation mishandled socket options. A local attacker could abuse concurrent access to the socket options to escalate their privileges, or cause a denial of service (use-after-free and system crash) via a crafted sendmsg system call. (CVE-2016-3841, Important)

* Several Moderate and Low impact security issues were found in the Linux kernel. Space precludes documenting each of these issues in this advisory. Refer to the CVE links in the References section for a description of each of these vulnerabilities. (CVE-2013-4312, CVE-2015-8374, CVE-2015-8543, CVE-2015-8812, CVE-2015-8844, CVE-2015-8845, CVE-2016-2053, CVE-2016-2069, CVE-2016-2847, CVE-2016-3156, CVE-2016-4581, CVE-2016-4794, CVE-2016-5412, CVE-2016-5828, CVE-2016-5829, CVE-2016-6136, CVE-2016-6198, CVE-2016-6327, CVE-2016-6480, CVE-2015-8746, CVE-2015-8956, CVE-2016-2117, CVE-2016-2384, CVE-2016-3070, CVE-2016-3699, CVE-2016-4569, CVE-2016-4578)

Red Hat would like to thank Philip Pettersson (Samsung) for reporting CVE-2016-2053; Tetsuo Handa for reporting CVE-2016-2847; the Virtuozzo kernel team and Solar Designer (Openwall) for reporting CVE-2016-3156;
Justin Yackoski (Cryptonite) for reporting CVE-2016-2117; and Linn Crosetto (HP) for reporting CVE-2016-3699. The CVE-2015-8812 issue was discovered by Venkatesh Pottem (Red Hat Engineering); the CVE-2015-8844 and CVE-2015-8845 issues were discovered by Miroslav Vadkerti (Red Hat Engineering); the CVE-2016-4581 issue was discovered by Eric W. Biederman (Red Hat); the CVE-2016-6198 issue was discovered by CAI Qian (Red Hat); and the CVE-2016-3070 issue was discovered by Jan Stancek (Red Hat).

The remote Ubuntu 14.04 LTS host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-2887-1 advisory.

    It was discovered that a use-after-free vulnerability existed in the AF_UNIX implementation in the Linux     kernel. A local attacker could use crafted epoll_ctl calls to cause a denial of service (system crash) or     expose sensitive information. (CVE-2013-7446)

    It was discovered that the KVM implementation in the Linux kernel did not properly restore the values of     the Programmable Interrupt Timer (PIT). A user-assisted attacker in a KVM guest could cause a denial of     service in the host (system crash). (CVE-2015-7513)

    Sasha Levin discovered that the Reliable Datagram Sockets (RDS) implementation in the Linux kernel had a     race condition when checking whether a socket was bound or not. A local attacker could use this to cause a     denial of service (system crash). (CVE-2015-7990)

    It was discovered that the Btrfs implementation in the Linux kernel incorrectly handled compressed inline     extants on truncation. A local attacker could use this to expose sensitive information. (CVE-2015-8374)

Tenable has extracted the preceding description block directly from the Ubuntu 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 remote Ubuntu 14.04 LTS host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-2890-2 advisory.

    It was discovered that a use-after-free vulnerability existed in the AF_UNIX implementation in the Linux     kernel. A local attacker could use crafted epoll_ctl calls to cause a denial of service (system crash) or     expose sensitive information. (CVE-2013-7446)

    It was discovered that the KVM implementation in the Linux kernel did not properly restore the values of     the Programmable Interrupt Timer (PIT). A user-assisted attacker in a KVM guest could cause a denial of     service in the host (system crash). (CVE-2015-7513)

    It was discovered that the Linux kernel keyring subsystem contained a race between read and revoke     operations. A local attacker could use this to cause a denial of service (system crash). (CVE-2015-7550)

    Sasha Levin discovered that the Reliable Datagram Sockets (RDS) implementation in the Linux kernel had a     race condition when checking whether a socket was bound or not. A local attacker could use this to cause a     denial of service (system crash). (CVE-2015-7990)

    It was discovered that the Btrfs implementation in the Linux kernel incorrectly handled compressed inline     extants on truncation. A local attacker could use this to expose sensitive information. (CVE-2015-8374)

     discovered that the Linux kernel networking implementation did not validate protocol identifiers     for certain protocol families, A local attacker could use this to cause a denial of service (system crash)     or possibly gain administrative privileges. (CVE-2015-8543)

    Dmitry Vyukov discovered that the pptp implementation in the Linux kernel did not verify an address length     when setting up a socket. A local attacker could use this to craft an application that exposed sensitive     information from kernel memory. (CVE-2015-8569)

    David Miller discovered that the Bluetooth implementation in the Linux kernel did not properly validate     the socket address length for Synchronous Connection-Oriented (SCO) sockets. A local attacker could use     this to expose sensitive information. (CVE-2015-8575)

    It was discovered that the netfilter Network Address Translation (NAT) implementation did not ensure that     data structures were initialized when handling IPv4 addresses. An attacker could use this to cause a     denial of service (system crash). (CVE-2015-8787)
