EulerOS 2.0 SP9 : dbus (EulerOS-SA-2021-2266)

high Nessus Plugin ID 152342

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 :

 - A use-after-free flaw was found in D-Bus Development branch <= 1.13.16, dbus-1.12.x stable branch <= 1.12.18, and dbus-1.10.x and older branches <= 1.10.30 when a system has multiple usernames sharing the same UID. When a set of policy rules references these usernames, D-Bus may free some memory in the heap, which is still used by data structures necessary for the other usernames sharing the UID, possibly leading to a crash or other undefined behaviors(CVE-2020-35512)

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.
