An authenticated attacker could     exploit this by mounting a gluster volume and sending a     string longer that the fixed buffer size to cause crash     or potential code execution.(CVE-2018-10907)

  - 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.(CVE-2018-10913)

  - 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.(CVE-2018-10914)

  - It was found that the 'mknod' call derived from     mknod(2) 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.(CVE-2018-10923)

According to the versions of the glusterfs packages installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :

  - A flaw was found in RPC request using gfs2_create_req     in glusterfs server. An authenticated attacker could     use this flaw to create arbitrary files and execute     arbitrary code on glusterfs server     nodes.(CVE-2018-10929)

  - A flaw was found in RPC request using gfs3_lookup_req     in glusterfs server. An authenticated attacker could     use this flaw to leak information and execute remote     denial of service by crashing gluster brick     process.(CVE-2018-10927)

  - A flaw was found in RPC request using gfs3_mknod_req     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.(CVE-2018-10926)

  - A flaw was found in RPC request using gfs3_rename_req     in glusterfs server. An authenticated attacker could     use this flaw to write to a destination outside the     gluster volume.(CVE-2018-10930)

  - A flaw was found in RPC request using gfs3_symlink_req     in glusterfs server which allows symlink destinations     to point to file paths outside of the gluster volume.
    An authenticated attacker could use this flaw to create     arbitrary symlinks pointing anywhere on the server and     execute arbitrary code on glusterfs server     nodes.(CVE-2018-10928)

  - 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. Attacker can use this flaw     to create files and execute arbitrary code. To exploit     this attacker would require sufficient access to modify     the extended attributes of files on a gluster     volume.(CVE-2018-10904)

Red Hat would like to thank Michael Hanselmann (hansmi.ch) for reporting CVE-2018-10904, CVE-2018-10907, CVE-2018-10923, CVE-2018-10926, CVE-2018-10927, CVE-2018-10928, CVE-2018-10929, CVE-2018-10930, CVE-2018-10911, CVE-2018-10914, CVE-2018-14652, CVE-2018-14653, CVE-2018-14654, CVE-2018-14659, CVE-2018-14660, CVE-2018-14661, and CVE-2018-10913. The CVE-2018-10873 issue was discovered by Frediano Ziglio (Red Hat).

Bug Fix(es) :

* When upgrading Red Hat Virtualization Host (RHVH), imgbased fails to run garbage collection on previous layers, so new logical volumes are removed, and the boot entry points to a logical volume that was removed.

If the RHVH upgrade finishes successfully, the hypervisor boots successfully, even if garbage collection fails. (BZ#1632058)

* During the upgrade process, when lvremove runs garbage collection, it prompts for user confirmation, causing the upgrade process to fail.
Now the process uses 'lvremove --force' when trying to remove logical volumes and does not fail even if garbage collection fails, and as a result, the upgrade process finishes successfully. (BZ#1632585)

Multiple security vulnerabilities were discovered in GlusterFS, a clustered file system. Buffer overflows and path traversal issues may lead to information disclosure, denial of service or the execution of arbitrary code.

To resolve the security vulnerabilities the following limitations were made in GlusterFS :

  - open,read,write on special files like char and block are     no longer permitted

  - io-stat xlator can dump stat info only to /run/gluster     directory

For Debian 8 'Jessie', these problems have been fixed in version 3.5.2-2+deb8u4.

We recommend that you upgrade your glusterfs packages.
