CVE: CVE-2019-3844
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 get new privileges through the execution of SUID binaries, which would allow to create binaries owned by the service transient group with the setgid bit set. A local attacker may use this flaw to access resources that will be owned by a potentially different service in the future, when the GID will be recycled. 系统版本:
KYLIN 3.3.x
