Security Bulletin
This security bulletin contains one medium risk vulnerability.
EUVDB-ID: #VU17474
Risk: Medium
CVSSv3.1: 7.6 [CVSS:3.1/AV:L/AC:L/PR:L/UI:R/S:C/C:H/I:H/A:H/E:F/RL:O/RC:C]
CVE-ID: CVE-2019-5736
CWE-ID:
CWE-264 - Permissions, Privileges, and Access Controls
Exploit availability: Yes
DescriptionThe vulnerability allows a remote attacker to gain elevated privileges.
The weakness exists in the runc container runtime due to file-descriptor mishandling, related to /proc/self/exe. A remote attacker can leverage 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, overwrite the host runc binary with minimal user interaction and execute arbitrary code with root privileges.
Successful exploitation of the vulnerability may result in system compromise.
Update the affected packages.
Opensuse: 15.1
