CVE: CVE-2019-3843
CVSS3评分: 4.5
概述:
This issue did not affect the versions of systemd as shipped with Kylin Enterprise Linux 7 as they did not include support for DynamicUser property. 描述:
It was discovered that a systemd service that uses DynamicUser property can create a SUID/SGID binary that would be allowed to run as the transient service UID/GID even after the service is terminated. A local attacker may use this flaw to access resources that will be owned by a potentially different service in the future, when the UID/GID will be recycled. 系统版本:
KYLIN 3.3.x
