Topic

Updated glusterfs packages that fix multiple security issues, several bugs, and adds various enhancements are now available for Red Hat Gluster Storage 3.4 on Red Hat Enterprise Linux 6.

Red Hat Product Security has rated this update as having a security impact of Important. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section.

Description

GlusterFS is a key building block of Red Hat Gluster Storage. It is based on a stackable user-space design and can deliver exceptional performance for diverse workloads. GlusterFS aggregates various storage servers over network interconnections into one large, parallel network file system.

Security Fix(es):

• glusterfs: Unsanitized file names in debug/io-stats translator can allow remote attackers to execute arbitrary code (CVE-2018-10904)
• glusterfs: Stack-based buffer overflow in server-rpc-fops.c allows remote attackers to execute arbitrary code (CVE-2018-10907)
• glusterfs: I/O to arbitrary devices on storage server (CVE-2018-10923)
• glusterfs: Device files can be created in arbitrary locations (CVE-2018-10926)
• glusterfs: File status information leak and denial of service (CVE-2018-10927)
• glusterfs: Improper resolution of symlinks allows for privilege escalation (CVE-2018-10928)
• glusterfs: Arbitrary file creation on storage server allows for execution of arbitrary code (CVE-2018-10929)
• glusterfs: Files can be renamed outside volume (CVE-2018-10930)
• glusterfs: Improper deserialization in dict.c:dict_unserialize() can allow attackers to read arbitrary memory (CVE-2018-10911)
• glusterfs: remote denial of service of gluster volumes via posix_get_file_contents function in posix-helpers.c (CVE-2018-10914)
• glusterfs: Information Exposure in posix_get_file_contents function in posix-helpers.c (CVE-2018-10913)
