Title: DeviceKit Storage Device Label Local Privilege Escalation Vulnerability
Severity: MODERATE
Description:
DeviceKit is a device enumeration toolkit similar to HAL.
The application is prone to a local privilege-escalation vulnerability because it fails to properly sanitize the labels of pluggable storage devices. Specifically, the '/' character was not stripped from label names prior to mount attempts.
Local attackers can exploit this issue to execute arbitrary code with the privileges of the user running the affected application. Successful exploits may aid in the compromise of affected computers.
Affected Products:
- Red Hat Fedora 11
- Red Hat Fedora 12
- freedesktop.org DeviceKit 002
