CVE-2018-14652 – glusterfs: Buffer overflow in "features/locks" translator allows for denial of service
https://notcve.org/view.php?id=CVE-2018-14652
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 'GF_XATTR_CLRLK_CMD' xattr in the 'pl_getxattr' function. A remote authenticated attacker could exploit this on a mounted volume to cause a denial of service. El sistema de archivos Gluster hasta las versiones 3.12 y 4.1.4 es vulnerable a un desbordamiento de búfer en el traductor "features/index" mediante el código que maneja el xattr "GF_XATTR_CLRLK_CMD" en la función "pl_getxattr". Un atacante autenticado remoto podría explotar esta vulnerabilidad en un volumen montado para provocar una denegación de servicio (DoS). A buffer overflow was found in strncpy of the pl_getxattr() function. • 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-2018-14652 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-2018-14652 https://bugzilla.redhat.com/show_bug.cg • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer CWE-120: Buffer Copy without Checking Size of Input ('Classic Buffer Overflow') •
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 •
CVE-2018-14661 – glusterfs: features/locks translator passes an user-controlled string to snprintf without a proper format string resulting in a denial of service
https://notcve.org/view.php?id=CVE-2018-14661
It was found that usage of snprintf function in feature/locks translator of glusterfs server 3.8.4, as shipped with Red Hat Gluster Storage, was vulnerable to a format string attack. A remote, authenticated attacker could use this flaw to cause remote denial of service. Se ha detectado que el uso de la función snprintf en el traductor feature/locks del servidor glusterfs 3.8.4, tal y como se distribuye con Red Hat Gluster Storage, era vulnerable a un ataque de cadena de formato. Un atacante remoto autenticado podría explotar este error para provocar una denegación de servicio (DoS).

CVE-2018-14653 – glusterfs: Heap-based buffer overflow via "gf_getspec_req" RPC message
https://notcve.org/view.php?id=CVE-2018-14653
The Gluster file system through versions 4.1.4 and 3.12 is vulnerable to a heap-based buffer overflow in the '__server_getspec' function via the 'gf_getspec_req' RPC message. A remote authenticated attacker could exploit this to cause a denial of service or other potential unspecified impact. El sistema de archivos Gluster hasta las versiones 3.12 y 4.1.4 es vulnerable a un desbordamiento de búfer basado en memoria dinámica (heap) en la función "__server_getspec" mediante el mensaje RPC "gf_getspec_req".
