Arch Linux Security Advisory ASA-202006-9 ========================================= Severity: Low Date : 2020-06-13 CVE-ID : CVE-2020-12049 Package : dbus Type : denial of service Remote : No Link : https://security.archlinux.org/AVG-1183 Summary ======= The package dbus before version 1.12.18-1 is vulnerable to denial of service. Resolution ========== Upgrade to 1.12.18-1. # pacman -Syu "dbus>=1.12.18-1" The problem has been fixed upstream in version 1.12.18. Workaround ========== None. Description =========== 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. Impact ====== A local attacker might be able to cause a denial of service via crafted DBUS messages.
