Package maintainers are required to ascertain if the flaw indeed affects their package, before starting the update process. unshield through 1.6.2 contains a heap out-of-bounds read vulnerability in unshield_get_file_table() that allows attackers to read past heap allocations via unchecked cabinet header offsets. Attackers can supply a crafted InstallShield cabinet with out-of-range file_table_offset or large file counts to crash the unshield tool or library consumers.
