Description
libphdi through 20260902 contains a heap out-of-bounds read vulnerability in libphdi_data_files_get_extent_data_file_path that uses the directory prefix length instead of the basename length. Attackers can supply a crafted Parallels disk image descriptor with a long directory prefix and short basename to crash the process or expose adjacent heap memory.
