EulerOS Virtualization 3.0.6.0 : dbus (EulerOS-SA-2023-2208)

high Nessus Plugin ID 177182

Synopsis

The remote EulerOS Virtualization host is missing multiple security updates.

Description

According to the versions of the dbus packages installed, the EulerOS Virtualization installation on the remote host is affected by the following vulnerabilities :

 - 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)

 - An issue was discovered in D-Bus before 1.12.24, 1.13.x and 1.14.x before 1.14.4, and 1.15.x before 1.15.2. An authenticated attacker can cause dbus-daemon and other programs that use libdbus to crash when receiving a message with certain invalid type signatures. (CVE-2022-42010)

 - An issue was discovered in D-Bus before 1.12.24, 1.13.x and 1.14.x before 1.14.4, and 1.15.x before 1.15.2. An authenticated attacker can cause dbus-daemon and other programs that use libdbus to crash when receiving a message where an array length is inconsistent with the size of the element type.
 (CVE-2022-42011)

 - An issue was discovered in D-Bus before 1.12.24, 1.13.x and 1.14.x before 1.14.4, and 1.15.x before 1.15.2. An authenticated attacker can cause dbus-daemon and other programs that use libdbus to crash by sending a message with attached file descriptors in an unexpected format. (CVE-2022-42012)

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 packages.
