Source-reported description

The fullest retained description is shown with its source. Distribution packaging descriptions may include downstream details.

UPX is a compressor for several different executable formats. Programs receive a stub that makes them self-runnable. When run, decompression either happens in memory in-place if possible, or to a temporary file, the latter of which does not support setuid programs, or the proper name in argv[0].
