EulerOS 2.0 SP5 : dbus (EulerOS-SA-2020-2242)

medium Nessus Plugin ID 142096

Synopsis

The remote EulerOS host is missing a security update.

Description

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

 - 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.(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.
