bzip2 Decompression File Overwrite Vulnerability

bzip2 is an open-source file compression/decompression utility for Unix and Linux variants.

bzip2 does not decompress files securely. When a file is decompressed, the program does not check to see if the file already exists, potentially allowing files to be overwritten without warning during the decompression.
