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.

FAQ: Is Azure Linux the only Microsoft product that includes this open-source library and is therefore potentially affected by this vulnerability?
One of the main benefits to our customers who choose to use the Azure Linux distro is the commitment to keep it up to date with the most recent and most secure versions of the open source libraries with which the distro is composed. Microsoft is committed to transparency in this work which i

CVE-2019-3843 systemd: services with DynamicUser can create SUID/SGID binaries
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.
Discussion:
A compromised or malicious service that uses DynamicUser property could leave on the filesystem a SUID/SGID binary that would allow other users to execute programs with the privileges of the transient user/group created by systemd. If the same UID/GID is reused by another service in the future, the SUID/SGID binary can be used to access the ne
