Vendor Workaround
Do not run gfs2-utils savemeta on untrusted or potentially compromised GFS2 filesystem images. Run gfs2-utils tools in a containerized or VM-isolated environment when processing untrusted images. Disable automatic fsck at boot for GFS2 filesystems until patches are applied by setting fs_passno to 0 in /etc/fstab.

| Description | A stack out-of-bounds write vulnerability was found in gfs2-utils. In savemeta, the height value from on-disk inode metadata is used as a loop bound without bounds checking, causing a stack buffer overflow that may lead to arbitrary code execution when processing crafted GFS2 filesystem images. | |
