The Gluster file system through versions 4.1.4 and 3.12 is vulnerable to a heap-based buffer overflow in the 'servergetspec' function via the 'gfgetspecreq' RPC message. A remote authenticated attacker could exploit this to cause a denial of service or other potential unspecified impact.

The Gluster file system through versions 4.1.4 and 3.1.2 is vulnerable to a denial of service attack via use of the 'GFXATTRIOSTATSDUMPKEY' xattr. A remote, authenticated attacker could exploit this by mounting a Gluster volume and repeatedly calling 'setxattr(2)' to trigger a state dump and create an arbitrary number of files in the server's runtime directory.

The Gluster file system through version 4.1.4 is vulnerable to abuse of the 'features/index' translator. A remote attacker with access to mount volumes could exploit this via the 'GFXATTROPENTRYINKEY' xattrop to create arbitrary, empty files on the target server.
