  "title": "GNU Tar through 1.35 allows file overwrite via directory traversal in crafted TAR archives, with a certain two-step process. First, the victim must extract an archive that contains a ../ symlink to a critical directory. Second, the victim must extract an archive that contains a critical file, specified via a relative pathname that begins with the symlink name and ends with that critical file\u0027s name. Here, the extraction follows the symlink and overwrites the critical file. This bypasses the protection mechanism of \u0022Member name contains \u0027..\u0027\u0022 that would occur for a single TAR archive that attempted to specify the critical file via a ../ approach. For example, the first archive can contain \u0022x -\u003E ../../../../../home/victim/.ssh\u0022 and the second archive can contain x/authorized_keys. This can affect server applications that automatically extract any number of user-supplied TAR archives, and were relying on the blocking of traversal. This can also affect software installation processes in wh",
