The Unity Linux 20 host has a package installed that is affected by a vulnerability as referenced in the UTSA-2026-001984 advisory.

    The skb_flow_dissect function in net/core/flow_dissector.c in the Linux kernel through 3.12 allows remote     attackers to cause a denial of service (infinite loop) via a small value in the IHL field of a packet with     IPIP encapsulation.

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 6 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2013:1490 advisory.

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

    * A flaw was found in the way IP packets with an Internet Header Length     (ihl) of zero were processed in the skb_flow_dissect() function in the     Linux kernel. A remote attacker could use this flaw to trigger an infinite     loop in the kernel, leading to a denial of service. (CVE-2013-4348,     Important)

    * A flaw was found in the way the Linux kernel's IPv6 implementation     handled certain UDP packets when the UDP Fragmentation Offload (UFO)     feature was enabled. A remote attacker could use this flaw to crash the     system or, potentially, escalate their privileges on the system.
    (CVE-2013-4387, Important)

    * A flaw was found in the way the Linux kernel handled the creation of     temporary IPv6 addresses. If the IPv6 privacy extension was enabled     (/proc/sys/net/ipv6/conf/eth0/use_tempaddr set to '2'), an attacker on     the local network could disable IPv6 temporary address generation, leading     to a potential information disclosure. (CVE-2013-0343, Moderate)

    * A flaw was found in the way the Linux kernel handled HID (Human Interface     Device) reports with an out-of-bounds Report ID. An attacker with physical     access to the system could use this flaw to crash the system or,     potentially, escalate their privileges on the system. (CVE-2013-2888,     Moderate)

    * Heap-based buffer overflow flaws were found in the way the     Pantherlord/GreenAsia game controller driver, the Logitech force feedback     drivers, and the Logitech Unifying receivers driver handled HID reports.
    An attacker with physical access to the system could use these flaws to     crash the system or, potentially, escalate their privileges on the system.
    (CVE-2013-2892, CVE-2013-2893, CVE-2013-2895, Moderate)

    * A NULL pointer dereference flaw was found in the way the N-Trig touch     screen driver handled HID reports. An attacker with physical access to the     system could use this flaw to crash the system, resulting in a denial of     service. (CVE-2013-2896, Moderate)

    * An information leak flaw was found in the way the Linux kernel's device     mapper subsystem, under certain conditions, interpreted data written to     snapshot block devices. An attacker could use this flaw to read data from     disk blocks in free space, which are normally inaccessible. (CVE-2013-4299,     Moderate)

    * A use-after-free flaw was found in the tun_set_iff() function in the     Universal TUN/TAP device driver implementation in the Linux kernel.
    A privileged user could use this flaw to crash the system or, potentially,     further escalate their privileges on the system. (CVE-2013-4343, Moderate)

    * An off-by-one flaw was found in the way the ANSI CPRNG implementation in     the Linux kernel processed non-block size aligned requests. This could lead     to random numbers being generated with less bits of entropy than expected     when ANSI CPRNG was used. (CVE-2013-4345, Moderate)

    * A flaw was found in the way the Linux kernel's IPv6 SCTP implementation     interacted with the IPsec subsystem. This resulted in unencrypted SCTP     packets being sent over the network even though IPsec encryption was     enabled. An attacker able to inspect these SCTP packets could use this flaw     to obtain potentially sensitive information. (CVE-2013-4350, Moderate)

    Red Hat would like to thank Fujitsu for reporting CVE-2013-4299 and Stephan     Mueller for reporting CVE-2013-4345. The CVE-2013-4348 issue was discovered     by Jason Wang of Red Hat.

    Bug fix:

    * RoCE appeared to be supported in the MRG Realtime kernel even when the     required user space packages from the HPN channel were not installed.
    The Realtime kernel now checks for the HPN channel packages before exposing     the RoCE interfaces. RoCE devices appear as plain 10GigE devices if the     needed HPN channel user space packages are not installed. (BZ#1012993)

    Users should upgrade to these updated packages, which upgrade the kernel-rt     kernel to version kernel-rt-3.8.13-rt14, and correct these issues.
    The system must be rebooted for this update to take effect.

Various bug and CVE fixes.

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

Multiple vulnerabilities has been found and corrected in the Linux kernel :

The ipc_rcu_putref function in ipc/util.c in the Linux kernel before 3.10 does not properly manage a reference count, which allows local users to cause a denial of service (memory consumption or system crash) via a crafted application (CVE-2013-4483).

The skb_flow_dissect function in net/core/flow_dissector.c in the Linux kernel through 3.12 allows remote attackers to cause a denial of service (infinite loop) via a small value in the IHL field of a packet with IPIP encapsulation (CVE-2013-4348).

The Linux kernel before 3.12, when UDP Fragmentation Offload (UFO) is enabled, does not properly initialize certain data structures, which allows local users to cause a denial of service (memory corruption and system crash) or possibly gain privileges via a crafted application that uses the UDP_CORK option in a setsockopt system call and sends both short and long packets, related to the ip_ufo_append_data function in net/ipv4/ip_output.c and the ip6_ufo_append_data function in net/ipv6/ip6_output.c (CVE-2013-4470).

The ext4_orphan_del function in fs/ext4/namei.c in the Linux kernel before 3.7.3 does not properly handle orphan-list entries for non-journal filesystems, which allows physically proximate attackers to cause a denial of service (system hang) via a crafted filesystem on removable media, as demonstrated by the e2fsprogs tests/f_orphan_extents_inode/image.gz test (CVE-2013-2015).

net/ipv6/ip6_output.c in the Linux kernel through 3.11.4 does not properly determine the need for UDP Fragmentation Offload (UFO) processing of small packets after the UFO queueing of a large packet, which allows remote attackers to cause a denial of service (memory corruption and system crash) or possibly have unspecified other impact via network traffic that triggers a large response packet (CVE-2013-4387).

The IPv6 SCTP implementation in net/sctp/ipv6.c in the Linux kernel through 3.11.1 uses data structures and function calls that do not trigger an intended configuration of IPsec encryption, which allows remote attackers to obtain sensitive information by sniffing the network (CVE-2013-4350).

The updated packages provides a solution for these security issues.
