EulerOS Virtualization for ARM 64 3.0.2.0 : dbus (EulerOS-SA-2020-1982)

medium Nessus Plugin ID 140352

Synopsis

The remote EulerOS Virtualization for ARM 64 host is missing a security update.

Description

According to the version of the dbus packages installed, the EulerOS Virtualization for ARM 64 installation on the remote host is affected by the following vulnerability :

- An uncontrolled resource consumption vulnerability was discovered in D-Bus. The DBusServer leaks file descriptors when a message exceeds the per-message file descriptor limit. This flaw allows a local attacker with access to the D-Bus system bus or another system service's private AF_UNIX socket, to make the system service reach its file descriptor limit, denying service to subsequent D-Bus clients. As a result, the system may become unusable for other users, and some services may stop working. The highest threat from this vulnerability is to system availability.(CVE-2020-12049)

Note that Tenable Network Security has extracted the preceding description block directly from the EulerOS security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Solution

Update the affected dbus package.
