  "title": "crun: crun is an open source OCI Container Runtime fully written in C",
  "description": "crun is an open source OCI Container Runtime fully written in C. Prior to version 1.28, crun\u0027s default device setup opens the container rootfs \u0060/dev\u0060 directory without \u0060O_NOFOLLOW\u0060. If an OCI bundle contains \u0060rootfs/dev\u0060 as a symlink and the bundle configuration does not mount \u0060/dev\u0060, crun follows that symlink and creates the default device nodes and stdio symlinks at the symlink target outside the container rootfs. In a local rootful crun replay, this created fixed device nodes and symlinks outside the rootfs before crun returned failure. A pre-existing file named \u0060ptmx\u0060 in the target directory was also replaced by crun\u0027s forced \u0060ptmx -\u003E pts/ptmx\u0060 symlink. Version 1.28 fixes the issue.",
