8748314b5b Fixed support for RAR 1.5 (algo15) and added test archive for unit testing. Rar 1.5 archive created using DOS version, which only supports uppercase characters, thus resulting in amending base class with 'UseCaseInsensitiveToVerify' toggle. 2023-02-21 21:28:38 +01:00

values in the local entry header.

d91e58f2cc Refs #248. Refs #132. Added a test case of a tar containing symlinks 
This is a source archive of the MoltenVK project from github, which is my use-case for SharpCompress.
I added a test case in the project, which should extract the tar, and validate any symlink targets with what the tar thinks it ought to be.

83f6690576 Recognise empty tar archives. 
Currently, when ArchiveFactory.Open is called on an empty tar archive, it throws due to being unable to determine the stream type. This fix allows it to recognise empty tar files by checking for whether the filename is empty, the size is empty and the entry type is defined. Add a test to try opening an empty archive.

80ceb1c375 fix: prevent extracting archived files outside of target path 
This PR is meant to fix an arbitrary file write vulnerability, that can be
achieved using a specially crafted zip archive, that holds path traversal
filenames. When the filename gets concatenated to the target extraction
directory, the final path ends up outside of the target folder.

A sample malicious zip file named Zip.Evil.zip was used,
and when running the code below, resulted in the creation of C:/Temp/evil.txt
outside of the intended target directory.

There are various possible ways to avoid this issue, some include checking
for .. (dot dot) characters in the filename, but the best solution in our
opinion is to check if the final target filename, starts with the target
folder (after both are resolved to their absolute path).

Stay secure,

912d7a8775 Lzip (#245) 
* First pass.  Writing isn't implemented on stream.  Tests are busted.

* LZipReader works...no file name :(

* LZipWriter works

* Writing tests are actually correct now.  LZipStream correctly writes trailer now.  lzip command line tool likes it.

* Add recommendation blurb

* Update notes for formats

* LZip isn't an archive format

* Attempting to fix and implement crc32

* LZip writing test passes

* Had to invert crc to check uncompressed data.
