Vulnerability Title
fuse-overlayfs release-1.x preserves SUID/SGID bits after truncate/open(O_TRUNC)
Vulnerability Description
fuse-overlayfs is an implementation of overlayfs in FUSE for rootless containers. Prior to 1.17, the release-1.x C branch preserves SUID and SGID mode bits in main.c during open(O_TRUNC) and truncate handling on a copied-up file, allowing a low-privileged process to leave the upper-layer file with mode 4777. This issue is fixed in version 1.17.
