Description Josh Bressers 2005-04-28 15:33:53 UTC
A directory traversal bug exists in multiple versions of gzip. When
compressing a file, gzip saves its original name but not its path inside
the compressed file. When using gunzip's "-N" option, the original name
found inside the compressed file will be used as the name to save the
decompressed file with. "gunzip -N" doesn't check if the original name inside
the compressed file has any "/" characters in it. This makes it possible to
create a malicious compressed file that when decompressed with "gunzip -N"
will create a file at an arbitrary location in the file system.
