Discussion

QNX Photon MicroGUI Multiple Utility Server Flag Buffer Overflow Vulnerabilities

Reportedly QNX Photon MicroGUI is affected by multiple buffer overflow vulnerabilities in MicroGUI utilities. These issues are due to a failure of the affected applications to validate user-supplied string lengths before copying them into finite process buffers.

An attacker may leverage these issues to execute arbitrary code on the affected system within the context of the vulnerable applications; the applications are typically setuid applications.
