NASL family Huawei Local Security Checks NASL id EULEROS_SA-2019-1488.NASL description According to the versions of the kernel packages installed, the EulerOS Virtualization installation on the remote host is affected by the following vulnerabilities : - A flaw was found in the way the Linux kernel handled IRET faults during the processing of NMIs. An unprivileged, local user could use this flaw to crash the system or, potentially (although highly unlikely), escalate their privileges on the system.(CVE-2015-5157) - A denial of service vulnerability was found in the WhiteHEAT USB Serial Driver (whiteheat_attach function in drivers/usb/serial/whiteheat.c). In the driver, the COMMAND_PORT variable was hard coded and set to 4 (5th element). The driver assumed that the number of ports would always be 5 and used port number 5 as the command port. However, when using a USB device in which the number of ports was set to a number less than 5 (for example, 3), the driver triggered a kernel NULL-pointer dereference. A non-privileged attacker could use this flaw to panic the host.(CVE-2015-5257) - A NULL pointer dereference flaw was found in the SCTP implementation. A local user could use this flaw to cause a denial of service on the system by triggering a kernel panic when creating multiple sockets in parallel while the system did not have the SCTP module loaded.(CVE-2015-5283) - It was found that the x86 ISA (Instruction Set Architecture) is prone to a denial of service attack inside a virtualized environment in the form of an infinite loop in the microcode due to the way (sequential) delivering of benign exceptions such as #AC (alignment check exception) is handled. A privileged user inside a guest could use this flaw to create denial of service conditions on the host kernel.(CVE-2015-5307) - A flaw was found in the way the Linux kernel last seen 2020-06-01 modified 2020-06-02 plugin id 124812 published 2019-05-13 reporter This script is Copyright (C) 2019-2020 and is owned by Tenable, Inc. or an Affiliate thereof. source https://www.tenable.com/plugins/nessus/124812 title EulerOS Virtualization 3.0.1.0 : kernel (EulerOS-SA-2019-1488) code # # (C) Tenable Network Security, Inc. # include("compat.inc"); if (description) { script_id(124812); script_version("1.4"); script_cvs_date("Date: 2020/01/17"); script_cve_id( "CVE-2015-5157", "CVE-2015-5257", "CVE-2015-5283", "CVE-2015-5307", "CVE-2015-5364", "CVE-2015-5366", "CVE-2015-5697", "CVE-2015-5707", "CVE-2015-6252", "CVE-2015-6526", "CVE-2015-6937", "CVE-2015-7312", "CVE-2015-7513", "CVE-2015-7515", "CVE-2015-7550", "CVE-2015-7566", "CVE-2015-7613", "CVE-2015-7799", "CVE-2015-7872", "CVE-2015-7990", "CVE-2015-8104", "CVE-2015-8215" ); script_bugtraq_id( 75510, 76005 ); script_name(english:"EulerOS Virtualization 3.0.1.0 : kernel (EulerOS-SA-2019-1488)"); script_summary(english:"Checks the rpm output for the updated packages."); script_set_attribute(attribute:"synopsis", value: "The remote EulerOS Virtualization host is missing multiple security updates."); script_set_attribute(attribute:"description", value: "According to the versions of the kernel packages installed, the EulerOS Virtualization installation on the remote host is affected by the following vulnerabilities : - A flaw was found in the way the Linux kernel handled IRET faults during the processing of NMIs.

A privileged user inside a guest could use this flaw to create denial of service conditions on the host kernel.(CVE-2015-5307) - A flaw was found in the way the Linux kernel's networking implementation handled UDP packets with incorrect checksum values. A remote attacker could potentially use this flaw to trigger an infinite loop in the kernel, resulting in a denial of service on the system, or cause a denial of service in applications using the edge triggered epoll functionality.(CVE-2015-5364) - A flaw was found in the way the Linux kernel's networking implementation handled UDP packets with incorrect checksum values. A remote attacker could potentially use this flaw to trigger an infinite loop in the kernel, resulting in a denial of service on the system, or cause a denial of service in applications using the edge triggered epoll functionality.(CVE-2015-5366) - A cross-boundary flaw was discovered in the Linux kernel software raid driver. The driver accessed a disabled bitmap where only the first byte of the buffer was initialized to zero. This meant that the rest of the request (up to 4095 bytes) was left and copied into user space. An attacker could use this flaw to read private information from user space that would not otherwise have been accessible.(CVE-2015-5697) - An integer-overflow vulnerability was found in the scsi block-request handling code in function start_req(). A local attacker could use specially crafted IOV requests to overflow a counter used in bio_map_user_iov()'s page calculation, and write past the end of the array that contains kernel-page pointers.(CVE-2015-5707) - A flaw was found in the way the Linux kernel's vhost driver treated userspace provided log file descriptor when processing the VHOST_SET_LOG_FD ioctl command. The file descriptor was never released and continued to consume kernel memory. A privileged local user with access to the /dev/vhost-net files could use this flaw to create a denial-of-service attack.(CVE-2015-6252) - A flaw was found in the way the Linux kernel's perf subsystem retrieved userlevel stack traces on PowerPC systems. A local, unprivileged user could use this flaw to cause a denial of service on the system by creating a special stack layout that would force the perf_callchain_user_64() function into an infinite loop.(CVE-2015-6526) - A NULL-pointer dereference vulnerability was discovered in the Linux kernel. The kernel's Reliable Datagram Sockets (RDS) protocol implementation did not verify that an underlying transport existed before creating a connection to a remote server. A local system user could exploit this flaw to crash the system by creating sockets at specific times to trigger a NULL pointer dereference.(CVE-2015-6937) - Multiple race conditions in the Advanced Union Filesystem (aufs) aufs3-mmap.patch and aufs4-mmap.patch patches for the Linux kernel 3.x and 4.x allow local users to cause a denial of service (use-after-free and BUG) or possibly gain privileges via a (1) madvise or (2) msync system call, related to mm/madvise.c and mm/msync.c.(CVE-2015-7312) - A divide-by-zero flaw was discovered in the Linux kernel built with KVM virtualization support(CONFIG_KVM). The flaw occurs in the KVM module's Programmable Interval Timer(PIT) emulation, when PIT counters for channel 1 or 2 are set to zero(0) and a privileged user inside the guest attempts to read these counters. A privileged guest user with access to PIT I/O ports could exploit this issue to crash the host kernel (denial of service).(CVE-2015-7513) - An out-of-bounds memory access flaw was found in the Linux kernel's aiptek USB tablet driver (aiptek_probe() function in drivers/input/tablet/aiptek.c). The driver assumed that the interface always had at least one endpoint. By using a specially crafted USB device with no endpoints on one of its interfaces, an unprivileged user with physical access to the system could trigger a kernel NULL pointer dereference, causing the system to panic.(CVE-2015-7515) - A NULL-pointer dereference flaw was found in the kernel, which is caused by a race between revoking a user-type key and reading from it. The issue could be triggered by an unprivileged user with a local account, causing the kernel to crash (denial of service).(CVE-2015-7550) - A flaw was found in the way the Linux kernel visor driver handles certain invalid USB device descriptors. The driver assumes that the device always has at least one bulk OUT endpoint. By using a specially crafted USB device (without a bulk OUT endpoint), an unprivileged user with physical access could trigger a kernel NULL-pointer dereference and cause a system panic (denial of service).(CVE-2015-7566) - A race condition flaw was found in the way the Linux kernel's IPC subsystem initialized certain fields in an IPC object structure that were later used for permission checking before inserting the object into a globally visible list. A local, unprivileged user could potentially use this flaw to elevate their privileges on the system.(CVE-2015-7613) - A flaw was discovered in the Linux kernel where issuing certain ioctl() -s commands to the '/dev/ppp' device file could lead to a NULL pointer dereference. A privileged user could use this flaw to cause a kernel crash and denial of service.(CVE-2015-7799) - It was found that the Linux kernel's keys subsystem did not correctly garbage collect uninstantiated keyrings. A local attacker could use this flaw to crash the system or, potentially, escalate their privileges on the system.(CVE-2015-7872) - A denial of service flaw was discovered in the Linux kernel, where a race condition caused a NULL pointer dereference in the RDS socket-creation code. A local attacker could use this flaw to create a situation in which a NULL pointer crashed the kernel.(CVE-2015-7990) - It was found that the x86 ISA (Instruction Set Architecture) is prone to a denial of service attack inside a virtualized environment in the form of an infinite loop in the microcode due to the way (sequential) delivering of benign exceptions such as #DB (debug exception) is handled. A privileged user inside a guest could use this flaw to create denial of service conditions on the host kernel.(CVE-2015-8104) - It was found that the Linux kernel's IPv6 network stack did not properly validate the value of the MTU variable when it was set. A remote attacker could potentially use this flaw to disrupt a target system's networking (packet loss) by setting an invalid MTU value, for example, via a NetworkManager daemon that is processing router advertisement packets running on the target system.(CVE-2015-8215) Note that Tenable Network Security has extracted the preceding description block directly from the EulerOS security advisory.

NASL family Debian Local Security Checks NASL id DEBIAN_DSA-3364.NASL description Several vulnerabilities have been discovered in the Linux kernel that may lead to a privilege escalation or denial of service. - CVE-2015-8215 It was discovered that NetworkManager would set IPv6 MTUs based on the values received in IPv6 RAs (Router Advertisements), without sufficiently validating these values. A remote attacker could exploit this attack to disable IPv6 connectivity. This has been mitigated by adding validation in the kernel. - CVE-2015-2925 Jann Horn discovered that when a subdirectory of a filesystem is bind-mounted into a container that has its own user and mount namespaces, a process with CAP_SYS_ADMIN capability in the user namespace can access files outside of the subdirectory. The default Debian configuration mitigated this as it does not allow unprivileged users to create new user namespaces. - CVE-2015-5156 Jason Wang discovered that when a virtio_net device is connected to a bridge in the same VM, a series of TCP packets forwarded through the bridge may cause a heap buffer overflow. A remote attacker could use this to cause a denial of service (crash) or possibly for privilege escalation. - CVE-2015-6252 Michael S. Tsirkin of Red Hat Engineering found that the vhost driver leaked file descriptors passed to it with the VHOST_SET_LOG_FD ioctl command. A privileged local user with access to the /dev/vhost-net file, either directly or via libvirt, could use this to cause a denial of service (hang or crash). - CVE-2015-6937 It was found that the Reliable Datagram Sockets (RDS) protocol implementation did not verify that an underlying transport exists when creating a connection. Depending on how a local RDS application initialised its sockets, a remote attacker might be able to cause a denial of service (crash) by sending a crafted packet. - CVE-2015-7312 Xavier Chantry discovered that the patch provided by the aufs project to correct behaviour of memory-mapped files from an aufs mount introduced a race condition in the msync() system call. Ben Hutchings found that it also introduced a similar bug in the madvise_remove() function. A local attacker could use this to cause a denial of service or possibly for privilege escalation. last seen 2020-06-01 modified 2020-06-02 plugin id 86050 published 2015-09-22 reporter This script is Copyright (C) 2015-2019 and is owned by Tenable, Inc. or an Affiliate thereof. source https://www.tenable.com/plugins/nessus/86050 title Debian DSA-3364-1 : linux - security update code # # (C) Tenable Network Security, Inc. # # The descriptive text and package checks in this plugin were # extracted from Debian Security Advisory DSA-3364.

NASL family Ubuntu Local Security Checks NASL id UBUNTU_USN-2778-1.NASL description It was discovered that the Linux kernel did not check if a new IPv6 MTU set by a user space application was valid. A remote attacker could forge a route advertisement with an invalid MTU that a user space daemon like NetworkManager would honor and apply to the kernel, causing a denial of service. (CVE-2015-0272) It was discovered that virtio networking in the Linux kernel did not handle fragments correctly, leading to kernel memory corruption. A remote attacker could use this to cause a denial of service (system crash) or possibly execute code with administrative privileges. (CVE-2015-5156) It was discovered that the Reliable Datagram Sockets (RDS) implementation in the Linux kernel did not verify sockets were properly bound before attempting to send a message, which could cause a NULL pointer dereference. An attacker could use this to cause a denial of service (system crash). (CVE-2015-6937) Ben Hutchings discovered that the Advanced Union Filesystem (aufs) for the Linux kernel did not correctly handle references of memory mapped files from an aufs mount. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code with administrative privileges. (CVE-2015-7312).
