  "title": "Gfs2-utils: gfs2-utils: stack overflow via alloca(1\u003C\u003Cdi_depth) in hash table traversal",
  "description": "A stack overflow vulnerability was found in gfs2-utils. The hash table traversal code in metawalk.c uses alloca() with an exponentially-derived size from the untrusted on-disk di_depth field without bounds validation. A crafted GFS2 filesystem image with a large di_depth value causes stack exhaustion and a denial of service when processed by fsck.gfs2, gfs2_edit, or savemeta.",
