Red Hat Security Advisory 2015-1918-01 – Red Hat Gluster Storage is a software only scale-out storage solution that provides flexible and affordable unstructured data storage. It unifies data storage and infrastructure, increases performance, and improves availability and manageability to meet enterprise-level storage challenges. Red Hat Gluster Storage’s Unified File and Object Storage is built on OpenStack’s Object Storage. A flaw was found in the way swiftonfile serialized and stored metadata on disk by using Python’s pickle module. A remote, authenticated user could use this flaw to execute arbitrary code on the storage node.

Ubuntu Security Notice 2778-1 – 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. 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. Various other issues were also addressed.

Ubuntu Security Notice 2770-1 – It was discovered that ContainerNode::parserInsertBefore in Blink would incorrectly proceed with a DOM tree insertion in some circumstances. If a user were tricked in to opening a specially crafted website, an attacker could potentially exploit this to bypass same origin restrictions. A use-after-free was discovered in the service worker implementation in Chromium. If a user were tricked in to opening a specially crafted website, an attacker could potentially exploit this to cause a denial of service via application crash, or execute arbitrary code with the privileges of the user invoking the program. Various other issues were also addressed.

Ubuntu Security Notice 2774-1 – 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. 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). Various other issues were also addressed.

Red Hat Security Advisory 2015-1917-01 – libwmf is a library for reading and converting Windows Metafile Format vector graphics. libwmf is used by applications such as GIMP and ImageMagick. It was discovered that libwmf did not correctly process certain WMF with embedded BMP images. By tricking a victim into opening a specially crafted WMF file in an application using libwmf, a remote attacker could possibly use this flaw to execute arbitrary code with the privileges of the user running the application.

Ubuntu Security Notice 2777-1 – 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. Benjamin Randazzo discovered an information leak in the md (multiple device) driver when the bitmap_info.file is disabled. A local privileged attacker could use this to obtain sensitive information from the kernel. Various other issues were also addressed.

Ubuntu Security Notice 2773-1 – 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. 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). Various other issues were also addressed.
