Test ID:	1.3.6.1.4.1.25623.1.1.10.2019.0068
Category:	Mageia Linux Local Security Checks
Title:	Mageia: Security Advisory (MGASA-2019-0068)
Summary:	The remote host is missing an update for the 'opencontainers-runc' package(s) announced via the MGASA-2019-0068 advisory.
Description:	Summary: The remote host is missing an update for the 'opencontainers-runc' package(s) announced via the MGASA-2019-0068 advisory. Vulnerability Insight: Not using pivot_root(2) leaves the host /proc around in the mount namespace so that it is possible to mount another /proc without any other submount, even if /proc in the container is not fully visible. This flaw allows an attacker to read and modify some parts of the Linux kernel memory (rhbz#1663068). runc through 1.0-rc6 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: a new container with an attacker-controlled image, or 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 (CVE-2019-5736). Affected Software/OS: 'opencontainers-runc' package(s) on Mageia 6. Solution: Please install the updated package(s). CVSS Score: 9.3 CVSS Vector: AV:N/AC:M/Au:N/C:C/I:C/A:C
