CVE-2010-2094

Multiple format string vulnerabilities in the phar extension in PHP 5.3 before 5.3.2 allow context-dependent attackers to obtain sensitive information (memory contents) and possibly execute arbitrary code via a crafted phar:// URI that is not properly handled by the (1) phar_stream_flush, (2) phar_wrapper_unlink, (3) phar_parse_url, or (4) phar_wrapper_open_url functions in ext/phar/stream.c; and the (5) phar_wrapper_open_dir function in ext/phar/dirstream.c, which triggers errors in the php_stream_wrapper_log_error function.
