PEAR ArchiveTar version 1.4.3 and earlier contains a CWE-502, CWE-915 vulnerability in the ArchiveTar class. There are several file operations with
$v_header['filename']as parameter (such as fileexists, isfile, isdir, etc). When extract is called without a specific prefix path, we can trigger unserialization by crafting a tar file withphar://[path_to_malicious_phar_file]as path. Object injection can be used to trigger destruct in the loaded PHP classes, e.g. the ArchiveTar class itself. With Archive_Tar object injection, arbitrary file deletion can occur because@unlink($this->_temp_tarname)is called. If another class with useful gadget is loaded, it may possible to cause remote code execution that can result in files being deleted or possibly modified. This vulnerability appears to have been fixed in 1.4.4. - References
