Description Sam Fowler 2018-09-25 05:33:35 UTC 
Gluster versions 3.12.14 and 4.1.4 included incomplete fixes for the vulnerabilities, CVE-2018-10927, CVE-2018-10928, CVE-2018-10929, CVE-2018-10930 and CVE-2018-10926. All five vulnerabilities remain exploitable via symlinks pointing to relative paths. A remote authenticated attacker could exploit one of these vulnerabilities to force a server to resolve target paths and achieve a maximum impact of arbitrary code execution.
