EyeLock Myris version 3.3.2 suffers from an unquoted search path issue impacting the service ‘MyrisService’ for Windows deployed as part of Myris solution. This could potentially allow an authorized but non-privileged local user to execute arbitrary code with elevated privileges on the system. A successful attempt would require the local user to be able to insert their code in the system root path undetected by the OS or other security applications where it could potentially be executed during application startup or reboot. If successful, the local user’s code would execute with the elevated privileges of the application.

LINE Instant Messenger versions before June 2016 suffer from authorization bypass and server-side request forgery vulnerabilities.

This bulletin summary lists nine released Microsoft security bulletins for August, 2016.

Ubuntu Security Notice 3054-1 – Ben Hawkes discovered an integer overflow in the Linux netfilter implementation. On systems running 32 bit kernels, a local unprivileged attacker could use this to cause a denial of service or possibly execute arbitrary code with administrative privileges. It was discovered that the keyring implementation in the Linux kernel did not ensure a data structure was initialized before referencing it after an error condition occurred. A local attacker could use this to cause a deni al of service. Various other issues were also addressed.

Ubuntu Security Notice 3056-1 – Ben Hawkes discovered an integer overflow in the Linux netfilter implementation. On systems running 32 bit kernels, a local unprivileged attacker could use this to cause a denial of service or possibly execute arbitrary code with administrative privileges. It was discovered that the keyring implementation in the Linux kernel did not ensure a data structure was initialized before referencing it after an error condition occurred. A local attacker could use this to cause a denial of service. Various other issues were also addressed.

Ubuntu Security Notice 3057-1 – Ben Hawkes discovered an integer overflow in the Linux netfilter implementation. On systems running 32 bit kernels, a local unprivileged attacker could use this to cause a denial of service or possibly execute arbitrary code with administrative privileges. It was discovered that the keyring implementation in the Linux kernel did not ensure a data structure was initialized before referencing it after an error condition occurred. A local attacker could use this to cause a denial of service. Various other issues were also addressed.

Red Hat Security Advisory 2016-1585-01 – KVM is a full virtualization solution for Linux on AMD64 and Intel 64 systems. The qemu-kvm packages provide the user-space component for running virtual machines using KVM. Security Fix: Quick emulator built with the virtio framework is vulnerable to an unbounded memory allocation issue. It was found that a malicious guest user could submit more requests than the virtqueue size permits. Processing a request allocates a VirtQueueElement and therefore causes unbounded memory allocation on the host controlled by the guest.

Red Hat Security Advisory 2016-1586-01 – KVM is a full virtualization solution for Linux on AMD64 and Intel 64 systems. The qemu-kvm-rhev package provides the user-space component for running virtual machines using KVM in environments managed by Red Hat Enterprise Virtualization Manager. Security Fix: Quick emulator built with the virtio framework is vulnerable to an unbounded memory allocation issue. It was found that a malicious guest user could submit more requests than the virtqueue size permits. Processing a request allocates a VirtQueueElement and therefore causes unbounded memory allocation on the host controlled by the guest.

Ubuntu Security Notice 3051-1 – It was discovered that the keyring implementation in the Linux kernel did not ensure a data structure was initialized before referencing it after a n error condition occurred. A local attacker could use this to cause a denial of service. Kangjie Lu discovered an information leak in the netlink implementation of the Linux kernel. A local attacker could use this to obtain sensitive information from kernel memory. Various other issues were also addressed.

Ubuntu Security Notice 3050-1 – Ben Hawkes discovered that the Linux netfilter implementation did not correctly perform validation when handling IPT_SO_SET_REPLACE events. A local unprivileged attacker could use this to cause a denial of service or possibly execute arbitrary code with administrative privileges. Vitaly Kuznetsov discovered that the Linux kernel did not properly suppress hugetlbfs support in X86 paravirtualized guests. An attacker in the guest Various other issues were also addressed.
