CVE-2019-18837

Name of the Vulnerable Software and Affected Versions crun versions prior to 0.10.5

Description An issue was discovered in crun where it doesn't correctly check whether a target is a symlink when a crafted image is used, resulting in access to files outside of the container. This issue is related to the libcrun/linux.c and libcrun/chroot realpath.c files.

Recommendations For versions prior to 0.10.5, update to version 0.10.5 or later to resolve the issue. As a temporary workaround, consider restricting access to crafted images to minimize the risk of exploitation.
