| Vector | AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H |
Name of the Vulnerable Software and Affected Versions
Gluster file system versions 3.1.2 through 4.1.4
Description
The issue allows a remote, authenticated attacker to perform a denial of service attack by utilizing the
GF XATTR IOSTATS DUMP KEY xattr. This can be exploited by mounting a Gluster volume and repeatedly calling setxattr(2) to trigger a state dump, resulting in the creation of an arbitrary number of files in the server's runtime directory.Recommendations
For versions 3.1.2 through 4.1.4, consider restricting access to the
GF XATTR IOSTATS DUMP KEY xattr to prevent exploitation.
As a temporary workaround, consider disabling the setxattr(2) function until a patch is available.
Restrict access to the Gluster volume to minimize the risk of exploitation.Fix
