High
| Vector | AV:L/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:H |
Name of the Vulnerable Software and Affected Versions
runc versions 1.0.0-rc95 through 1.1.4
Description
The issue is related to the libcontainer/rootfs linux.go component of the runc tool, which is used for running isolated containers. It allows an attacker to exploit incorrect access control, potentially leading to escalation of privileges. This can be achieved by spawning two containers with custom volume-mount configurations and running custom images. The vulnerability exists due to a regression of a previous issue.
Recommendations
For versions 1.0.0-rc95 through 1.1.4, consider disabling the
libcontainer/rootfs linux.go component as a temporary workaround until a patch is available. Restrict access to custom volume-mount configurations and custom images to minimize the risk of exploitation. At the moment, there is no information about a newer version that contains a fix for this vulnerability.Exploit
