Overview
Affected versions of this package are vulnerable to Infinite loop due to an unbounded loop in the GPT partition scan process when the FF_LBA64 configuration is set to 1. An attacker can cause the system to hang or become unresponsive by providing a crafted GPT header with a large GPTH_PtNum value, resulting in extremely long or infinite mount-time scans.
