CVE-2018-14660 – glusterfs: Repeat use of "GF_META_LOCK_KEY" xattr allows for memory exhaustion
https://notcve.org/view.php?id=CVE-2018-14660
A flaw was found in glusterfs server through versions 4.1.4 and 3.1.2 which allowed repeated usage of GF_META_LOCK_KEY xattr. A remote, authenticated attacker could use this flaw to create multiple locks for single inode by using setxattr repetitively resulting in memory exhaustion of glusterfs server node. Se ha encontrado un error en el servidor glusterfs hasta las versiones 4.1.4 y 3.1.2 que permitía el uso repetido del xattr GF_META_LOCK_KEY. Un atacante autenticado remoto podría emplear este error para crear múltiples bloqueos para un único inode mediante el uso repetido de setxattr, lo que resulta en el agotamiento de la memoria del nodo del servidor glusterfs. A flaw was found in glusterfs server which allowed repeated usage of GF_META_LOCK_KEY xattr. • 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-2018-14660 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-2018-14660 https://bugzilla.redhat.com/show_bug.cgi?id=1635926 • CWE-400: Uncontrolled Resource Consumption CWE-770: Allocation of Resources Without Limits or Throttling •

CVE-2018-10914 – glusterfs: remote denial of service of gluster volumes via posix_get_file_contents function in posix-helpers.c
https://notcve.org/view.php?id=CVE-2018-10914
It was found that an attacker could issue a xattr request via glusterfs FUSE to cause gluster brick process to crash which will result in a remote denial of service. If gluster multiplexing is enabled this will result in a crash of multiple bricks and gluster volumes. Se ha descubierto que un atacante podría lanzar una petición xattr mediante glusterfs FUSE para provocar que el proceso brick de gluster se cierre inesperadamente, lo que resultará en una denegación de servicio (DoS) remota. Si gluster multiplexing está habilitado, esto resultará en el cierre inesperado de múltiples bloques y volúmenes de gluster. • http://lists.opensuse.org/opensuse-security-announce/2020-01/msg00035.html https://access.redhat.com/errata/RHSA-2018:2607 https://access.redhat.com/errata/RHSA-2018:2608 https://access.redhat.com/errata/RHSA-2018:3470 https://bugzilla.redhat.com/show_bug.cgi?id=CVE-2018-10914 https://lists.debian.org/debian-lts-announce/2018/09/msg00021.html https://lists.debian.org/debian-lts-announce/2021/11/msg00000.html https://security.gentoo.org/glsa/201904-06 https://access.redhat.c • CWE-476: NULL Pointer Dereference •
