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."

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.

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.

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.

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.

The rm_rf_children function in util.c in the systemd-logind login manager in systemd before 44, when logging out, allows local users to delete arbitrary files via a symlink attack on unspecified files, related to "particular records related with user session."

Stack-based buffer overflow in the RtlQueryRegistryValues function in win32k.sys in Microsoft Windows XP SP2 and SP3, Windows Server 2003 SP2, Windows Vista SP1 and SP2, Windows Server 2008 Gold, SP2, and R2, and Windows 7 allows local users to gain privileges, and bypass the User Account Control (UAC) feature, via a crafted REG_BINARY value for a SystemDefaultEUDCFont registry key, aka "Driver Improper Interaction with Windows Kernel Vulnerability."

Direct static code injection vulnerability in sysinfo.cgi in sysinfo 1.21 and possibly other versions before 2.25 allows remote attackers to execute arbitrary commands via a leading ; (semicolon) in the name parameter in a systemdoc action, which is injected into phpinfo.php.
