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.
