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 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.

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.
