Arch Linux Security Advisory ASA-201902-20 ========================================== Severity: High Date : 2019-02-17 CVE-ID : CVE-2019-5736 Package : flatpak Type : privilege escalation Remote : Yes Link : https://security.archlinux.org/AVG-880 Summary ======= The package flatpak before version 1.2.3-1 is vulnerable to privilege escalation. Resolution ========== Upgrade to 1.2.3-1. # pacman -Syu "flatpak>=1.2.3-1" The problem has been fixed upstream in version 1.2.3. Workaround ========== None. Description =========== A vulnerability discovered in runc through 1.0-rc6, as used in Docker before 18.09.2 and other products, allows attackers to overwrite the host runc binary (and consequently obtain host root access) by leveraging the ability to execute a command as root within one of these types of containers: (1) a new container with an attacker-controlled image, or (2) an existing container, to which the attacker previously had write access, that can be attached with docker exec. This occurs because of file-descriptor mishandling, related to /proc/self/exe. Impact ====== A malicious container can escalate privileges to gain access as root on the host system and execute arbitrary code.
