Directory traversal vulnerability in Info-ZIP UnZip 5.42 and earlier allows attackers to overwrite arbitrary files during archive extraction via a .. (dot dot) in an extracted filename.

Info-ZIP UnZip 5.42 and earlier allows attackers to overwrite arbitrary files during archive extraction via filenames in the archive that begin with the '/' (slash) character.

Buffer overflow in UnZip 5.50 and earlier allows user-assisted attackers to execute arbitrary code via a long filename command line argument. NOTE: since the overflow occurs in a non-setuid program, there are not many scenarios under which it poses a vulnerability, unless unzip is passed long arguments when it is invoked from other programs.
