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.<br>Security Fix(es):<br><li> systemd: uncontrolled allocation on the stack in function unitnamepathescape leads to crash (CVE-2021-33910)</li> 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.
