| VCID-1qhk-r5sq-zqhm | Path traversal in SharpZipLib SharpZipLib (or #ziplib) is a Zip, GZip, Tar and BZip2 library. A check was added if the destination file is under a destination directory. However, it is not enforced that `_baseDirectory` ends with slash. If the `_baseDirectory` is not slash terminated like `/home/user/dir` it is possible to create a file with a name thats begins as the destination directory one level up from the directory, i.e. `/home/user/dir.sh`. Because of the file name and destination directory constraints, the arbitrary file creation impact is limited and depends on the use case. fixed this vulnerability. |
