CVE-2020-13776 3 Fedoraproject, Netapp, Systemd Project 4 Fedora, Active Iq Unified Manager, Solidfire \& Hci Management Node and 1 more 2022-01-31 6.2 MEDIUM 6.7 MEDIUM
systemd through v245 mishandles numerical usernames such as ones composed of decimal digits or 0x followed by hex digits, as demonstrated by use of root privileges when privileges of the 0x0 user account were intended. NOTE: this issue exists because of an incomplete fix for CVE-2017-1000082.
CVE-2018-16888 4 Canonical, Netapp, Redhat and 1 more 5 Ubuntu Linux, Active Iq Performance Analytics Services, Element Software and 2 more 2022-01-31 1.9 LOW 4.7 MEDIUM
It was discovered systemd does not correctly check the content of PIDFile files before using it to kill processes. When a service is run from an unprivileged user (e.g. User field set in the service file), a local attacker who is able to write to the PIDFile of the mentioned service may use this flaw to trick systemd into killing other services and/or privileged processes. Versions before v237 are vulnerable.
CVE-2018-15688 4 Canonical, Debian, Redhat and 1 more 9 Ubuntu Linux, Debian Linux, Enterprise Linux Desktop and 6 more 2022-01-31 5.8 MEDIUM 8.8 HIGH
A buffer overflow vulnerability in the dhcp6 client of systemd allows a malicious dhcp6 server to overwrite heap memory in systemd-networkd. Affected releases are systemd: versions up to and including 239.
CVE-2018-15687 2 Canonical, Systemd Project 2 Ubuntu Linux, Systemd 2022-01-31 6.9 MEDIUM 7.0 HIGH
A race condition in chown_one() of systemd allows an attacker to cause systemd to set arbitrary permissions on arbitrary files. Affected releases are systemd versions up to and including 239.
CVE-2018-15686 4 Canonical, Debian, Oracle and 1 more 4 Ubuntu Linux, Debian Linux, Communications Cloud Native Core Network Function Cloud Native Environment and 1 more 2022-01-31 7.2 HIGH 7.8 HIGH
A vulnerability in unit_deserialize of systemd allows an attacker to supply arbitrary state across systemd re-execution via NotifyAccess. This can be used to improperly influence systemd execution and possibly lead to root privilege escalation. Affected releases are systemd versions up to and including 239.
CVE-2018-1049 4 Canonical, Debian, Redhat and 1 more 11 Ubuntu Linux, Debian Linux, Enterprise Linux and 8 more 2022-01-31 4.3 MEDIUM 5.9 MEDIUM
In systemd prior to 234 a race condition exists between .mount and .automount units such that automount requests from kernel may not be serviced by systemd resulting in kernel holding the mountpoint and any processes that try to use said mount will hang. A race condition like this may lead to denial of service, until mount points are unmounted.
CVE-2018-6954 3 Canonical, Opensuse, Systemd Project 3 Ubuntu Linux, Leap, Systemd 2022-01-31 7.2 HIGH 7.8 HIGH
systemd-tmpfiles in systemd through 237 mishandles symlinks present in non-terminal path components, which allows local users to obtain ownership of arbitrary files via vectors involving creation of a directory and a file under that directory, and later replacing that directory with a symlink. This occurs even if the fs.protected_symlinks sysctl is turned on.
CVE-2017-18078 3 Debian, Opensuse, Systemd Project 3 Debian Linux, Leap, Systemd 2022-01-31 4.6 MEDIUM 7.8 HIGH
systemd-tmpfiles in systemd before 237 attempts to support ownership/permission changes on hardlinked files even if the fs.protected_hardlinks sysctl is turned off, which allows local users to bypass intended access restrictions via vectors involving a hard link to a file for which the user lacks write access, as demonstrated by changing the ownership of the /etc/passwd file.
CVE-2017-1000082 1 Systemd Project 1 Systemd 2022-01-31 10.0 HIGH 9.8 CRITICAL
systemd v233 and earlier fails to safely parse usernames starting with a numeric digit (e.g. "0day"), running the service in question with root privileges rather than the user intended.
CVE-2017-9445 1 Systemd Project 1 Systemd 2022-01-31 5.0 MEDIUM 7.5 HIGH
In systemd through 233, certain sizes passed to dns_packet_new in systemd-resolved can cause it to allocate a buffer that's too small. A malicious DNS server can exploit this via a response with a specially crafted TCP payload to trick systemd-resolved into allocating a buffer that's too small, and subsequently write arbitrary data beyond the end of it.
CVE-2017-9217 1 Systemd Project 1 Systemd 2022-01-31 5.0 MEDIUM 7.5 HIGH
systemd-resolved through 233 allows remote attackers to cause a denial of service (daemon crash) via a crafted DNS response with an empty question section.
CVE-2013-4394 2 Debian, Systemd Project 2 Debian Linux, Systemd 2022-01-31 5.9 MEDIUM N/A
The SetX11Keyboard function in systemd, when PolicyKit Local Authority (PKLA) is used to change the group permissions on the X Keyboard Extension (XKB) layouts description, allows local users in the group to modify the Xorg X11 Server configuration file and possibly gain privileges via vectors involving "special and control characters."
CVE-2013-4393 1 Systemd Project 1 Systemd 2022-01-31 2.1 LOW N/A
journald in systemd, when the origin of native messages is set to file, allows local users to cause a denial of service (logging service blocking) via a crafted file descriptor.
CVE-2013-4392 1 Systemd Project 1 Systemd 2022-01-31 3.3 LOW N/A
systemd, when updating file permissions, allows local users to change the permissions and SELinux security contexts for arbitrary files via a symlink attack on unspecified files.
CVE-2013-4391 2 Debian, Systemd Project 2 Debian Linux, Systemd 2022-01-31 7.5 HIGH N/A
Integer overflow in the valid_user_field function in journal/journald-native.c in systemd allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via a large journal data field, which triggers a heap-based buffer overflow.
CVE-2013-4327 3 Canonical, Debian, Systemd Project 3 Ubuntu Linux, Debian Linux, Systemd 2022-01-31 6.9 MEDIUM N/A
systemd does not properly use D-Bus for communication with a polkit authority, which allows local users to bypass intended access restrictions by leveraging a PolkitUnixProcess PolkitSubject race condition via a (1) setuid process or (2) pkexec process, a related issue to CVE-2013-4288.
CVE-2019-20386 5 Canonical, Fedoraproject, Netapp and 2 more 7 Ubuntu Linux, Fedora, Active Iq Unified Manager and 4 more 2022-01-28 2.1 LOW 2.4 LOW
An issue was discovered in button_open in login/logind-button.c in systemd before 243. When executing the udevadm trigger command, a memory leak may occur.
CVE-2012-0871 2 Opensuse, Systemd Project 2 Opensuse, Systemd 2022-01-28 6.3 MEDIUM N/A
The session_link_x11_socket function in login/logind-session.c in systemd-logind in systemd, possibly 37 and earlier, allows local users to create or overwrite arbitrary files via a symlink attack on the X11 user directory in /run/user/.
CVE-2012-1101 1 Systemd Project 1 Systemd 2022-01-28 2.1 LOW 5.5 MEDIUM
systemd 37-1 does not properly handle non-existent services, which causes a denial of service (failure of login procedure).
CVE-2015-7510 1 Systemd Project 1 Systemd 2022-01-28 7.5 HIGH 9.8 CRITICAL
Stack-based buffer overflow in the getpwnam and getgrnam functions of the NSS module nss-mymachines in systemd.
