Name of the Vulnerable Software and Affected Versions: systemd versions prior to 247 Description: The issue is related to inadequate blocking of local privilege escalation for some Sudo configurations, specifically when the "systemctl status" command may be executed. This is due to systemd not...

The vulnerability of the initialization and service management subsystems in Linux’s systemd, related to resource management errors, allows attackers to gain access to confidential data, compromise its integrity, and cause service failures.

The vulnerability of the initialization and service management subsystems in Linux’s systemd is related to resource management errors. Exploiting this vulnerability can allow an attacker to access confidential data, compromise its integrity, and even cause service failures using the shutdown...

The vulnerability of the systemd_run function on the vdsm control server of the virtual infrastructure management tool Ovirt allows a attacker to execute arbitrary code.

The vulnerability of the systemdrun function in the VDS management tool of the Ovirt virtual infrastructure involves a lack of measures taken to clean data at the management level. Exploiting this vulnerability allows an attacker operating remotely to execute arbitrary code...

The vulnerability of the Linux systemd initialization process, related to the access to memory after it is freed, allows a perpetrator to gain access to confidential data, compromise its integrity, and cause service failures.

The vulnerability of the Linux systemd initialization process is related to an error in the handling of the queue after it is freed from memory. Asynchronous Polkit requests are executed when processing dbus messages. Exploiting this vulnerability allows an attacker to gain access to confidential...

Privilege Escalation

systemd is vulnerable to privilege escalation. The vulnerability exists as services with DynamicUser can create SUID/SGID binaries...

DEBIAN-CVE-2020-1712

A heap use-after-free vulnerability was found in systemd before version v245-rc1, where asynchronous Polkit queries are performed while handling dbus messages. A local unprivileged attacker can abuse this flaw to crash systemd services or potentially execute code and elevate their privileges, by...

CVE-2012-1101

systemd 37-1 does not properly handle non-existent services, which causes a denial of service failure of login procedure...

systemd: line splitting via fgets() allows for state injection during daemon-reexec

It was discovered that systemd is vulnerable to a state injection attack when deserializing the state of a service. Properties longer than LINEMAX are not correctly parsed and an attacker may abuse this flaw in particularly configured services to inject, change, or corrupt the service state...

systemd: use-after-free when asynchronous polkit queries are performed

A heap use-after-free vulnerability was found in systemd, where asynchronous Polkit queries are performed while handling dbus messages. A local unprivileged attacker can abuse this flaw to crash systemd services or potentially execute code and elevate their privileges, by sending specially crafte...

CVE-2019-20386

An issue was discovered in buttonopen in login/logind-button.c in systemd before 243. When executing the udevadm trigger command, a memory leak may occur...

UBUNTU-CVE-2019-15718

In systemd 240, busopensystemwatchbindwithdescription in shared/bus-util.c as used by systemd-resolved to connect to the system D-Bus instance, calls sdbussettrusted, which disables access controls for incoming D-Bus messages. An unprivileged user can exploit this by executing D-Bus methods that...

NewStart CGSL MAIN 5.04 : systemd Vulnerability (NS-SA-2019-0014)

The remote NewStart CGSL host, running version MAIN 5.04, has systemd packages installed that are affected by a vulnerability: - A race condition was found in systemd. This could result in automount requests not being serviced and processes using them could hang, causing denial of service...

CVE-2019-3843

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...

CVE-2019-3842

In systemd before v242-rc4, it was discovered that pamsystemd does not properly sanitize the environment before using the XDGSEAT variable. It is possible for an attacker, in some particular configurations, to set a XDGSEAT environment variable which allows for commands to be checked against polk...

USN-3938-1 systemd vulnerability

Jann Horn discovered that pamsystemd created logind sessions using some parameters from the environment. A local attacker could exploit this in order to spoof the active session and gain additional PolicyKit privileges...

DEBIAN-CVE-2019-6454

An issue was discovered in sd-bus in systemd 239. busprocessobject in libsystemd/sd-bus/bus-objects.c allocates a variable-length stack buffer for temporarily storing the object path of incoming D-Bus messages. An unprivileged local user can exploit this by sending a specially crafted message to...

systemd: Insufficient input validation in bus_process_object() resulting in PID 1 crash

It was discovered that systemd allocates a buffer large enough to store the path field of a dbus message without performing enough checks. A local attacker may trigger this flaw by sending a dbus message to systemd with a large path making systemd crash or possibly elevating his privileges...

USN-3891-1 systemd vulnerability

It was discovered that systemd incorrectly handled certain D-Bus messages. A local unprivileged attacker could exploit this in order to crash the init process, resulting in a system denial-of-service kernel panic...

PT-2022-4312 · Systemd +7 · Systemd +7

Name of the Vulnerable Software and Affected Versions: systemd affected versions not specified Description: A use-after-free issue was found in systemd due to the on stream io function and dns stream complete function in 'resolved-dns-stream.c' not incrementing the reference counting for the...

The vulnerability of the systemd daemon in the Astra Linux operating system allows a hacker to circumvent the restrictions imposed by a given security policy.

The vulnerability of the systemd-based Astra Linux operating system is related to the absence of mandate-based integrity control during operations involving systemd. Exploiting this vulnerability allows an attacker to circumvent the restrictions imposed by the specified security policies...
