Guido Vranken discovered that an incorrect bounds check in ZeroMQ, a lightweight messaging kernel, could result in the execution of arbitrary code.

A pointer overflow, with code execution, was discovered in ZeroMQ libzmq 4.2.x and 4.3.x before 4.3.1. A v2_decoder.cpp zmq::v2_decoder_t::size_ready integer overflow allows an authenticated attacker to overwrite an arbitrary amount of bytes beyond the bounds of a buffer, which can be leveraged to run arbitrary code on the target system. The memory layout allows the attacker to inject OS commands ...

webkit2gtk: Web content engine library for GTK+ Several security issues were fixed in WebKitGTK+.

A vulnerability was discovered in runc, which is used by Docker to run containers. runc did not prevent container processes from modifying the runc binary via /proc/self/exe. A malicious container could replace the runc binary, resulting in container escape and privilege escalation. This was fixed by creating a per-container copy of runc.

The runC tool is a lightweight, portable implementation of the Open Container Format that provides container runtime. Security Fix: * A flaw was found in the way runc handled system file descriptors when running containers. A malicious container could use this flaw to overwrite contents of the runc binary and consequently run arbitrary commands on the container host system. Additional details ab ...

Docker is an open-source engine that automates the deployment of any application as a lightweight, portable, self-sufficient container that runs virtually anywhere. Security Fix: * A flaw was found in the way runc handled system file descriptors when running containers. A malicious container could use this flaw to overwrite contents of the runc binary and consequently run arbitrary commands on the ...
