Meanwhile, mitigate by running fsck.gfs2, gfs2_edit, and savemeta in isolated environments and disabling automatic filesystem checks at boot to prevent automatic triggering of the vulnerable code.
Description
A stack overflow vulnerability in gfs2-utils allows local users to cause denial of service by triggering stack exhaustion via crafted GFS2 filesystem images. The issue arises from unbounded use of alloca() based on the di_depth field in untrusted images, affecting tools like fsck.gfs2, gfs2_edit, and savemeta. This vulnerability requires local access and user interaction and does not impact the kernel GFS2 driver. Mitigations include running affected tools in isolated environments and disabling automatic filesystem checks at boot until patched.
