RHSA-2018:2608: Important: Red Hat Gluster Storage security, bug fix, and enhancement update
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.<br>Security Fix(es):<br><li> glusterfs: Unsanitized file names in debug/io-stats translator can allow remote attackers to execute arbitrary code (CVE-2018-10904)</li> <li> glusterfs: Stack-based buffer overflow in server-rpc-fops.c allows remote attackers to execute arbitrary code (CVE-2018-10907)</li> <li> glusterfs: I/O to arbitrary devices on storage server (CVE-2018-10923)</li> <li> glusterfs: Device files can be created in arbitrary locations (CVE-2018-10926)</li> <li> glusterfs: File status information leak and denial of service (CVE-2018-10927)</li> <li> glusterfs: Improper resolution of symlinks allows for privilege escalation (CVE-2018-10928)</li> <li> glusterfs: Arbitrary file creation on storage server allows for execution of arbitrary code (CVE-2018-10929)</li> <li> glusterfs: Files can be renamed outside volume (CVE-2018-10930)</li> <li> glusterfs: Improper deserialization in dict.c:dictunserialize() can allow attackers to read arbitrary memory (CVE-2018-10911)</li> <li> glusterfs: remote denial of service of gluster volumes via posixgetfilecontents function in posix-helpers.c (CVE-2018-10914)</li> <li> glusterfs: Information Exposure in posixgetfilecontents function in posix-helpers.c (CVE-2018-10913)</li> For more details about the security issue(s), including the impact, a CVSS score, and other related information, refer to the CVE page(s) listed in the References section.<br>Red Hat would like to thank Michael Hanselmann (hansmi.ch) for reporting these issues.<br>Additional changes:<br>These updated Red Hat Gluster Storage packages include numerous bug fixes and enhancements.
