CVE-2019-3843 is fixed in 18 products on 1 platform, first by libnss-myhostname 237-3ubuntu10.38, released February 5, 2020. It is not reported as exploited. Patch Radar priority: High. - Web page: https://patchblox.com/security/cve/CVE-2019-3843 - Priority: High - CVSS: 7.8 (Moderate) - EPSS: 0.0094 - CISA KEV: not listed - Exploited (vendor report): no - Publicly disclosed: no - Published: Apr 26, 2019 ## Description The systemd packages contain systemd, a system and service manager for Linux, compatible with the SysV and LSB init scripts. It provides aggressive parallelism capabilities, uses socket and D-Bus activation for starting services, offers on-demand starting of daemons, and keeps track of processes using Linux cgroups. In addition, it supports snapshotting and restoring of the system state, maintains mount and automount points, and implements an elaborate transactional dependency-based service control logic. It can also work as a drop-in replacement for sysvinit. Security Fix(es): * systemd: services with DynamicUser can create SUID/SGID binaries (CVE-2019-3843) * systemd: services with DynamicUser can get new privileges and create SGID binaries (CVE-2019-3844) 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.
