CVE-2018-1123

Status Candidate

Overview

procps-ng before version 3.3.15 is vulnerable to a denial of service in ps via mmap buffer overflow. Inbuilt protection in ps maps a guard page at the end of the overflowed buffer, ensuring that the impact of this flaw is limited to a crash (temporary denial of service).

Red Hat Security Advisory 2018-2147-01
Posted Jul 10, 2018
Authored by Red Hat | Site access.redhat.com

Red Hat Security Advisory 2018-2147-01 - Git is a distributed revision control system with a decentralized architecture. As opposed to centralized version control systems with a client-server model, Git ensures that each working copy of a Git repository is an exact copy with complete revision history. This not only allows the user to work on and contribute to projects without the need to have permission to push the changes to their official repositories, but also makes it possible for the user to work with no network connection. Issues addressed include a code execution vulnerability.

Ubuntu Security Notice USN-3671-1
Posted Jun 6, 2018
Authored by Ubuntu | Site security.ubuntu.com

Ubuntu Security Notice 3671-1 - Etienne Stalmans discovered that git did not properly validate git submodules files. A remote attacker could possibly use this to craft a git repo that causes arbitrary code execution when "git clone --recurse-submodules" is used. It was discovered that an integer overflow existed in git's pathname sanity checking code when used on NTFS filesystems. An attacker could use this to cause a denial of service or expose sensitive information. Various other issues were also addressed.
