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

  - crypto/ahash.c in the Linux kernel through 4.10.9 allows attackers to cause a denial of service (API     operation calling its own callback, and infinite recursion) by triggering EBUSY on a full queue.
    (CVE-2017-7618)

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

The 4.10.10 stable kernel update contains a number of important fixes across the tree.

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

The Unity Linux 20 host has a package installed that is affected by a vulnerability as referenced in the UTSA-2026-001574 advisory.

    crypto/ahash.c in the Linux kernel through 4.10.9 allows attackers to cause a denial of service (API     operation calling its own callback, and infinite recursion) by triggering EBUSY on a full queue.

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 OracleVM system is missing necessary patches to address critical security updates : please see Oracle VM Security Advisory OVMSA-2017-0174 for details.

The openSUSE Leap 42.2 kernel was updated to 4.4.62 to receive various security and bugfixes.

The following security bugs were fixed :

  - CVE-2017-7618: crypto/ahash.c in the Linux kernel     allowed attackers to cause a denial of service (API     operation calling its own callback, and infinite     recursion) by triggering EBUSY on a full queue     (bnc#1033340).

  - CVE-2016-4997: The compat IPT_SO_SET_REPLACE and     IP6T_SO_SET_REPLACE setsockopt implementations in the     netfilter subsystem in the Linux kernel allowed local     users to gain privileges or cause a denial of service     (memory corruption) by leveraging in-container root     access to provide a crafted offset value that triggers     an unintended decrement (bnc#986362).

  - CVE-2016-4998: The IPT_SO_SET_REPLACE setsockopt     implementation in the netfilter subsystem in the Linux     kernel allowed local users to cause a denial of service     (out-of-bounds read) or possibly obtain sensitive     information from kernel heap memory by leveraging     in-container root access to provide a crafted offset     value that leads to crossing a ruleset blob boundary     (bnc#986365).

  - CVE-2017-7616: Incorrect error handling in the     set_mempolicy and mbind compat syscalls in     mm/mempolicy.c in the Linux kernel allowed local users     to obtain sensitive information from uninitialized stack     data by triggering failure of a certain bitmap operation     (bnc#1033336).

  - CVE-2017-2671: The ping_unhash function in     net/ipv4/ping.c in the Linux kernel was too late in     obtaining a certain lock and consequently cannot ensure     that disconnect function calls are safe, which allowed     local users to cause a denial of service (panic) by     leveraging access to the protocol value of IPPROTO_ICMP     in a socket system call (bnc#1031003).

  - CVE-2017-7308: The packet_set_ring function in     net/packet/af_packet.c in the Linux kernel did not     properly validate certain block-size data, which allowed     local users to cause a denial of service (overflow) or     possibly have unspecified other impact via crafted     system calls (bnc#1031579).

  - CVE-2017-7294: The vmw_surface_define_ioctl function in     drivers/gpu/drm/vmwgfx/vmwgfx_surface.c in the Linux     kernel did not validate addition of certain levels data,     which allowed local users to trigger an integer overflow     and out-of-bounds write, and cause a denial of service     (system hang or crash) or possibly gain privileges, via     a crafted ioctl call for a /dev/dri/renderD* device     (bnc#1031440).

  - CVE-2017-7261: The vmw_surface_define_ioctl function in     drivers/gpu/drm/vmwgfx/vmwgfx_surface.c in the Linux     kernel did not check for a zero value of certain levels     data, which allowed local users to cause a denial of     service (ZERO_SIZE_PTR dereference, and GPF and possibly     panic) via a crafted ioctl call for a /dev/dri/renderD*     device (bnc#1031052).

  - CVE-2017-7187: The sg_ioctl function in     drivers/scsi/sg.c in the Linux kernel allowed local     users to cause a denial of service (stack-based buffer     overflow) or possibly have unspecified other impact via     a large command size in an SG_NEXT_CMD_LEN ioctl call,     leading to out-of-bounds write access in the sg_write     function (bnc#1030213).

  - CVE-2017-7374: Use-after-free vulnerability in     fs/crypto/ in the Linux kernel allowed local users to     cause a denial of service (NULL pointer dereference) or     possibly gain privileges by revoking keyring keys being     used for ext4, f2fs, or ubifs encryption, causing     cryptographic transform objects to be freed prematurely     (bnc#1032006).

The Unity Linux 20 host has a package installed that is affected by a vulnerability as referenced in the UTSA-2026-003261 advisory.

    crypto/ahash.c in the Linux kernel through 4.10.9 allows attackers to cause a denial of service (API     operation calling its own callback, and infinite recursion) by triggering EBUSY on a full queue.

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.

Infinite recursion in ahash.c by triggering EBUSY on a full queue :

A vulnerability was found in crypto/ahash.c in the Linux kernel which allows attackers to cause a denial of service (API operation calling its own callback, and infinite recursion) by triggering EBUSY on a full queue.(CVE-2017-7618)

Time subsystem allows local users to discover real PID values :

The time subsystem in the Linux kernel, when CONFIG_TIMER_STATS is enabled, allows local users to discover real PID values (as distinguished from PID values inside a PID namespace) by reading the /proc/timer_list file, related to the print_timer function in kernel/time/timer_list.c and the __timer_stats_timer_set_start_info function in kernel/time/timer.c.(CVE-2017-5967)

Stack-based buffer overflow in sg_ioctl function :

The sg_ioctl function in drivers/scsi/sg.c in the Linux kernel allows local users to cause a denial of service (stack-based buffer overflow) or possibly have unspecified other impacts via a large command size in an SG_NEXT_CMD_LEN ioctl call, leading to out-of-bounds write access in the sg_write function. (CVE-2017-7187)

Incorrect error handling in the set_mempolicy and mbind compat syscalls in mm/mempolicy.c :

Incorrect error handling in the set_mempolicy() and mbind() compat syscalls in mm/mempolicy.c; in the Linux kernel allows local users to obtain sensitive information from uninitialized stack data by triggering failure of a certain bitmap operation. (CVE-2017-7616)

Race condition in Link Layer Control :

A race condition leading to a NULL pointer dereference was found in the Linux kernel's Link Layer Control implementation. A local attacker with access to ping sockets could use this flaw to crash the system.
(CVE-2017-2671)

Overflow in check for priv area size :

It was found that the packet_set_ring() function of the Linux kernel's networking implementation did not properly validate certain block-size data. A local attacker with CAP_NET_RAW capability could use this flaw to trigger a buffer overflow, resulting in the crash of the system.
Due to the nature of the flaw, privilege escalation cannot be fully ruled out, although we believe it is unlikely. (CVE-2017-7308)
