Kernel: KVM: error in exception handling leads to wrong debug stack value

kernel KVM before versions kernel 4.16, kernel 4.16-rc7, kernel 4.17-rc1, kernel 4.17-rc2 and kernel 4.17-rc3 is vulnerable to a flaw in the way the Linux kernel's KVM hypervisor handled exceptions delivered after a stack switch operation via Mov SS or Pop SS instructions. During the stack switch operation, the processor did not deliver interrupts and exceptions, rather they are delivered once the first instruction after the stack switch is executed. An unprivileged KVM guest user could use this flaw to crash the guest or, potentially, escalate their privileges in the guest.

xen: Nested VT-x usable even when disabled

An issue was discovered in Xen 4.9.x through 4.11.x, on Intel x86 platforms, allowing x86 HVM and PVH guests to cause a host OS denial of service (NULL pointer dereference) or possibly have unspecified other impact because nested VT-x is not properly restricted.

systemd: kills privileged process if unprivileged PIDFile was tampered

It was discovered systemd does not correctly check the content of PIDFile files before using it to kill processes. When a service is run from an unprivileged user (e.g. User field set in the service file), a local attacker who is able to write to the PIDFile of the mentioned service may use this flaw to trick systemd into killing other services and/or privileged processes. Versions before v237 are vulnerable.

docker: container breakout without selinux in enforcing mode

The default OCI linux spec in oci/defaults{_linux}.go in Docker/Moby from 1.11 to current does not block /proc/acpi pathnames. The flaw allows an attacker to modify host's hardware like enabling/disabling bluetooth or turning up/down keyboard brightness.

kernel: error in exception handling leads to DoS (CVE-2018-8897 regression)

A flaw was found in the way the Linux kernel handled exceptions delivered after a stack switch operation via Mov SS or Pop SS instructions. During the stack switch operation, processor does not deliver interrupts and exceptions, they are delivered once the first instruction after the stack switch is executed. An unprivileged system user could use this flaw to crash the system kernel resulting in DoS. This CVE-2018-10872 was assigned due to regression of CVE-2018-8897 in Red Hat Enterprise Linux 6.10 GA kernel. No other versions are affected by this CVE.

podman: Containers run as non-root users do not drop capabilities

It has been discovered that podman before version 0.6.1 does not drop capabilities when executing a container as a non-root user. This results in unnecessary privileges being granted to the container.

kernel: kvm: guest userspace to guest kernel write

A flaw was found in the way Linux kernel KVM hypervisor before 4.18 emulated instructions such as sgdt/sidt/fxsave/fxrstor. It did not check current privilege(CPL) level while emulating unprivileged instructions. An unprivileged guest user/process could use this flaw to potentially escalate privileges inside guest.

Mozilla: Linux file truncation via sandbox broker (MFSA 2017-18)

On Linux systems, if the content process is compromised, the sandbox broker will allow files to be truncated even though the sandbox explicitly only has read access to the local file system and no write permissions. Note: This attack only affects the Linux operating system. Other operating systems are not affected. This vulnerability affects Firefox < 55.

Kernel: KVM: debug exception via syscall emulation

A flaw was found in the Linux kernel before version 4.12 in the way the KVM module processed the trap flag(TF) bit in EFLAGS during emulation of the syscall instruction, which leads to a debug exception(#DB) being raised in the guest stack. A user/process inside a guest could use this flaw to potentially escalate their privileges inside the guest. Linux guests are not affected by this.

Dell SmartFabric OS10 Software, version(s) 10.5.6.x, 10.5.5.x, 10.5.4.x, 10.5.3.x, contain(s) an Execution with Unnecessary Privileges vulnerability. A low privileged attacker with local access could potentially exploit this vulnerability, leading to Command execution

Cisco ATA 190 Series Analog Telephone Adapter Firmware Privilege Escalation Vulnerability

A vulnerability in the web-based management interface of Cisco ATA 190 Series Analog Telephone Adapter firmware could allow an authenticated, remote attacker with low privileges to run commands as an Admin user. This vulnerability is due to incorrect authorization verification by the HTTP server. An attacker could exploit this vulnerability by sending a malicious request to the web-based management interface. A successful exploit could allow the attacker to run commands as the Admin user.

A vulnerability has been identified in InterMesh 7177 Hybrid 2.0 Subscriber (All versions < V8.2.12), InterMesh 7707 Fire Subscriber (All versions < V7.2.12 only if the IP interface is enabled (which is not the default configuration)). The web server of affected devices allows to write arbitrary files to the web server's DocumentRoot directory.

Untrusted search path vulnerability in the AprolConfigureCCServices of B&R APROL

An untrusted search path vulnerability in the AprolConfigureCCServices of B&R APROL <= R 4.2.-07P3 and <= R 4.4-00P3 may allow an authenticated local attacker to execute arbitrary code with elevated privileges.

Untrusted search path vulnerability in B&R APROL

An untrusted search path vulnerability in B&R APROL <= R 4.4-00P3 may be used by an authenticated local attacker to get other users to execute arbitrary code under their privileges.

A vulnerability has been identified in SINEC NMS (All versions < V3.0). The affected application executes a subset of its services as `NT AUTHORITY\SYSTEM`. This could allow a local attacker to execute operating system commands with elevated privileges.
