CVE-ID : CVE-2020-12049
Package : dbus
Type : denial of service
Remote : No
Link : https://security.archlinux.org/AVG-1183
The package dbus before version 1.12.18-1 is vulnerable to denial of
service.
Upgrade to 1.12.18-1.
The problem has been fixed upstream in version 1.12.18.
None.
An issue was discovered in dbus >= 1.3.0 before 1.12.18. The DBusServer
in libdbus, as used in dbus-daemon, leaks file descriptors when a
message exceeds the per-message file descriptor limit. A local attacker
with access to the D-Bus system bus or another system service’s private
AF_UNIX socket could use this to make the system service reach its file
descriptor limit, denying service to subsequent D-Bus clients.
A local attacker might be able to cause a denial of service via crafted
DBUS messages.
