Overview
Affected versions of this package are vulnerable to Race Condition Enabling Link Following in the handling of procfs file writes. An attacker can cause arbitrary writes to sensitive files or trigger a denial of service by redirecting write operations through race conditions and manipulating shared mounts or symbolic links. This can result in bypassing security mechanisms, escalating privileges, or crashing the host system by targeting files such as /proc/sysrq-trigger or altering kernel parameters.
Workaround
This vulnerability can be mitigated by:
Do not run untrusted container images from unknown or unverified sources.
Using rootless containers.
