Security update for the Linux Kernel (important)

The openSUSE Leap 42.3 kernel was updated to 4.4.90 to receive various security and bugfixes. The following security bugs were fixed: - CVE-2017-1000252: The KVM subsystem in the Linux kernel allowed guest OS users to cause a denial of service assertion failure, and hypervisor hang or crash via a...

x86: Incorrect handling of self-linear shadow mappings with translated guests

ISSUE DESCRIPTION The shadow pagetable code uses linear mappings to inspect and modify the shadow pagetables. A linear mapping which points back to itself is known as self-linear. For translated guests, the shadow linear mappings being in a separate address space are not intended to be self-linea...

Unlimited recursion in linear pagetable de-typing

ISSUE DESCRIPTION x86 PV guests are permitted to set up certain forms of what is often called "linear page tables", where pagetables contain references to other pagetables at the same level or higher. Certain restrictions apply in order to fit into Xen's page type handling system. An important...

DMOP map/unmap missing argument checks

ISSUE DESCRIPTION DMOPs which were a subgroup of HVMOPs in older releases allow guests to control and drive other guests. The I/O request server page mapping interface uses range sets to represent I/O resources the emulation of which is provided by a given I/O request server. The internals of the...

Xen Hypervisor Memory Leak on Boot (XSA-235)

According to its self-reported version number, the Xen hypervisor installed on the remote host is affected by flaw within the pagealloc.c and asm-arm/numa.h due to not scrubbing the memory on boot. This could potentially leave sensitive information available to read after a reboot. This issue onl...

ARM Trusted Firmware Authentication Vulnerability

ARM Trusted Firmware is an implementation of multiple ARM interface standards. A security vulnerability exists in the BL1 FWU SMC handling code in ARM Trusted Firmware versions prior to 1.4. The vulnerability can be exploited by an attacker with the help of a specially crafted AArch32 image to...

ARM: Some memory not scrubbed at boot

ISSUE DESCRIPTION Data can remain readable in DRAM across soft and even hard reboots. To ensure that sensitive data is not leaked from one domain to another after a reboot, Xen must "scrub" all memory on boot write it with zeroes. Unfortunately, it was discovered that when memory was in disjoint...

First Android Malware Found Exploiting Dirty COW Linux Flaw to Gain Root Privileges

Nearly a year after the disclosure of the Dirty COW vulnerability that affected the Linux kernel, cybercriminals have started exploiting the vulnerability against Android users, researchers have warned. Publicly disclosed last year in October, Dirty COW was present in a section of the Linux...
