The Gluster file system through versions 3.12 and 4.1.4 is vulnerable to a buffer overflow in the 'features/index' translator via the code handling the 'GFXATTRCLRLKCMD' xattr in the 'plgetxattr' function. A remote authenticated attacker could exploit this on a mounted volume to cause a denial of service.
