Overview
Affected versions of this package are vulnerable to Out-of-bounds Write through the HLINK_BUMP process when handling file entries with the FLAG_HLINKED flag set while the hard-link preservation option is inactive. An attacker can corrupt adjacent heap or stack memory by crafting file entries that trigger access past the end of the allocated structure.
