EulerOS Virtualization for ARM 64 3.0.2.0 : glusterfs (EulerOS-SA-2020-1525)

high Nessus Plugin ID 136228

Synopsis

The remote EulerOS Virtualization for ARM 64 host is missing multiple security updates.

Description

According to the versions of the glusterfs packages installed, the EulerOS Virtualization for ARM 64 installation on the remote host is affected by the following vulnerabilities :

 - 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 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_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)

 - 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)

 - 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)

 - It was found that glusterfs server is vulnerable to multiple stack based buffer overflows due to functions in server-rpc-fopc.c allocating fixed size buffers using 'alloca(3)'. 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)

Note that Tenable Network Security has extracted the preceding description block directly from the EulerOS security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Solution

Update the affected glusterfs packages.
