glusterfs: Repeat use of "GF_META_LOCK_KEY" xattr allows for memory exhaustion

A flaw was found in glusterfs server which allowed repeated usage of GFMETALOCKKEY 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...

glusterfs: "features/index" translator can create arbitrary, empty files

A flaw was found in the way glusterfs server handles client requests. A remote, authenticated attacker could set arbitrary values for the GFXATTROPENTRYINKEY and GFXATTROPENTRYOUTKEY during xattrop file operation resulting in creation and deletion of arbitrary files on glusterfs server node...

glusterfs: Information Exposure in posix_get_file_contents function in posix-helpers.c

An information disclosure vulnerability was discovered in glusterfs server. An attacker could issue a xattr request via glusterfs FUSE to determine the existence of any file...

glusterfs: I/O to arbitrary devices on storage server

It was found that the "mknod" call derived from mknod2 can create files pointing to devices on a glusterfs server node. An authenticated attacker could use this to create an arbitrary device and read data from any device attached to the glusterfs server node...

glusterfs: Stack-based buffer overflow in server-rpc-fops.c allows remote attackers to execute arbitrary code

It was found that glusterfs server is vulnerable to mulitple stack based buffer overflows due to functions in server-rpc-fopc.c allocating fixed size buffers using 'alloca3'. An authenticated attacker could exploit this by mounting a gluster volume and sending a string longer that the fixed buffe...

glusterfs: remote denial of service of gluster volumes via posix_get_file_contents function in posix-helpers.c

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...

Moderate: Red Hat Security Advisory: Red Hat Virtualization security and bug fix update

Red Hat Product Security has rated this update as having a security impact of Moderate. A Common Vulnerability Scoring System CV...

glusterfs: Device files can be created in arbitrary locations

A flaw was found in RPC request using gfs3mknodreq supported by glusterfs server. An authenticated attacker could use this flaw to write files to an arbitrary location via path traversal and execute arbitrary code on a glusterfs server node...

glusterfs: Unsanitized file names in debug/io-stats translator can allow remote attackers to execute arbitrary code

It was found that glusterfs server does not properly sanitize file paths in the "trusted.io-stats-dump" extended attribute which is used by the "debug/io-stats" translator. An attacker can use this flaw to create files and execute arbitrary code. To exploit this, the attacker would require...

glusterfs: Unlimited file creation via "GF_XATTR_IOSTATS_DUMP_KEY" xattr allows for denial of service

A flaw was found in glusterfs server which allowed clients to create io-stats dumps on server node. A remote, authenticated attacker could use this flaw to create io-stats dump on a server without any limitation and utilizing all available inodes resulting in remote denial of service...

glusterfs: File status information leak and denial of service

A flaw was found in RPC request using gfs3lookupreq in glusterfs server. An authenticated attacker could use this flaw to leak information and execute remote denial of service by crashing gluster brick process...

glusterfs: features/locks translator passes an user-controlled string to snprintf without a proper format string resulting in a denial of service

It was found that usage of snprintf function in feature/locks translator of glusterfs server was vulnerable to a format string attack. A remote, authenticated attacker could use this flaw to cause remote denial of service...

glusterfs: Heap-based buffer overflow via "gf_getspec_req" RPC message

A buffer overflow on the heap was found in gfgetspecreq RPC request. A remote, authenticated attacker could use this flaw to cause denial of service and read arbitrary files on glusterfs server node...

glusterfs: Buffer overflow in "features/locks" translator allows for denial of service

A buffer overflow was found in strncpy of the plgetxattr function. An authenticated attacker could remotely overflow the buffer by sending a buffer of larger length than the size of the key resulting in remote denial of service...
