Description

Updated udisks2 & libblockdev packages fix security vulnerabilities

A Local Privilege Escalation (LPE) vulnerability was found in

libblockdev. Generally, the "allow_active" setting in Polkit permits a

physically present user to take certain actions based on the session

type. Due to the way libblockdev interacts with the udisks daemon, an

"allow_active" user on a system may be able escalate to full root

privileges on the target host. Normally, udisks mounts user-provided

filesystem images with security flags like nosuid and nodev to prevent

privilege escalation. However, a local attacker can create a specially

crafted XFS image containing a SUID-root shell, then trick udisks into

resizing it. This mounts their malicious filesystem with root

privileges, allowing them to execute their SUID-root shell and gain

complete control of the system.
