What it is

Reported

A Local Privilege Escalation (LPE) vulnerability was found in libblockdev.

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.… Source description excerpt; complete tracked detail loads below.
