CVE-2018-14659 – glusterfs: Unlimited file creation via "GF_XATTR_IOSTATS_DUMP_KEY" xattr allows for denial of service

https://notcve.org/view.php?id=CVE-2018-14659

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 'GF_XATTR_IOSTATS_DUMP_KEY' 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. El sistema de archivos Gluster hasta las versiones 3.12 y 4.1.4 es vulnerable a un ataque de denegación de servicio (DoS) mediante el uso del xattr "GF_XATTR_IOSTATS_DUMP_KEY". Un atacante autenticado remoto podría explotar esta vulnerabilidad montando un volumen Gluster y llamando repetidamente a "setxattr(2)" para desencadenar un volcado de estado y crear un número arbitrario de archivos en el directorio runtime del servidor. A flaw was found in glusterfs server which allowed clients to create io-stats dumps on server node. • https://access.redhat.com/errata/RHSA-2018:3431 https://access.redhat.com/errata/RHSA-2018:3432 https://access.redhat.com/errata/RHSA-2018:3470 https://bugzilla.redhat.com/show_bug.cgi?id=CVE-2018-14659 https://lists.debian.org/debian-lts-announce/2018/11/msg00003.html https://lists.debian.org/debian-lts-announce/2021/11/msg00000.html https://security.gentoo.org/glsa/201904-06 https://access.redhat.com/security/cve/CVE-2018-14659 https://bugzilla.redhat.com/show_bug.cg • CWE-400: Uncontrolled Resource Consumption •
