Summary
Red Hat Security Advisory: targetcli security update

Notes

Topic
An update for targetcli is now available for Red Hat Enterprise Linux 7. Red Hat Product Security has rated this update as having a security impact of Moderate. 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.
Details
The targetcli package contains an administration shell for configuring Internet Small Computer System Interface (iSCSI), Fibre Channel over Ethernet (FCoE), and other SCSI targets, using the Target Core Mod/Linux-IO (TCM/LIO) kernel target subsystem. FCoE users also need to install and use the fcoe-utils package. The following packages have been upgraded to a later upstream version: targetcli (2.1.53). (BZ#1853645) Security Fix(es): * targetcli: weak permissions for /etc/target and backup files (CVE-2020-13867) For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section.
