For example it is nowadays even supporting SVG files. + +Such a big parsing library can easily be haunted by security related bugs as for example [CVE-2014-2053](https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2014-2053) +and some other vulnerabilities have proven. This library takes the ID3 parsing code from getID3 and strips all other +functions. + +In cases where reading the ID3v2 tags is sufficient this library is likely to be a more secure approach, if you need any +of the advanced features of getID3 however you're likely to be unhappy with this library. diff --git a/vendor/lukasreschke/id3parser/composer.json b/vendor/lukasreschke/id3parser/composer.json new file mode 100644 index 000000000..897ca3410 --- /dev/null +++ b/vendor/lukasreschke/id3parser/composer.json @@ -0,0 +1,14 @@ +{ + "name": "lukasreschke/id3parser", + "homepage" : "https://github.com/LukasReschke/ID3Parser/", + "require" : { + "php" : ">=5.4.0" + }, + "license": "GPL", + "keywords": ["php","tags","codecs"], + "autoload" : { + "psr-4" : { + "ID3Parser\\" : "src/" + } + } +} diff --git a/vendor/lukasreschke/id3parser/src/ID3Parser.php b/vendor/lukasreschke/id3parser/src/ID3Parser.php new file mode 100644 index 000000000..f87a8b7dc --- /dev/null +++ b/vendor/lukasreschke/id3parser/src/ID3Parser.php @@ -0,0 +1,22 @@ + // +// available at http://getid3.sourceforge.net // +// or http://www.getid3.org // +// also https://github.com/JamesHeinrich/getID3 // +///////////////////////////////////////////////////////////////// + +namespace ID3Parser; + +use ID3Parser\getID3\getID3; + +class ID3Parser { + /** + * @param string $fileName + * @return array + */ + public function analyze($fileName) { + $getID3 = new getID3(); + return $getID3->analyze($fileName); + } +} diff --git a/vendor/lukasreschke/id3parser/src/getID3/Tags/getid3_id3v1.php b/vendor/lukasreschke/id3parser/src/getID3/Tags/getid3_id3v1.php new file mode 100644 index 000000000..18e850af1 --- /dev/null +++ b/vendor/lukasreschke/id3parser/src/getID3/Tags/getid3_id3v1.php @@ -0,0 +1,356 @@ + // +// available at http://getid3.sourceforge.net // +// or http://www.getid3.org // +// also https://github.com/JamesHeinrich/getID3 // +///////////////////////////////////////////////////////////////// + +namespace ID3Parser\getID3\Tags; + +use ID3Parser\getID3\getid3_handler; +use ID3Parser\getID3\getid3_lib; + +class getid3_id3v1 extends getid3_handler +{ + + public function Analyze() { + $info = &$this->getid3->info; + + if (!getid3_lib::intValueSupported($info['filesize'])) { + $info['warning'][] = 'Unable to check for ID3v1 because file is larger than '.round(PHP_INT_MAX / 1073741824).'GB'; + return false; + } + + $this->fseek(-256, SEEK_END); + $preid3v1 = $this->fread(128); + $id3v1tag = $this->fread(128); + + if (substr($id3v1tag, 0, 3) == 'TAG') { + + $info['avdataend'] = $info['filesize'] - 128; + + $ParsedID3v1['title'] = $this->cutfield(substr($id3v1tag, 3, 30)); + $ParsedID3v1['artist'] = $this->cutfield(substr($id3v1tag, 33, 30)); + $ParsedID3v1['album'] = $this->cutfield(substr($id3v1tag, 63, 30)); + $ParsedID3v1['year'] = $this->cutfield(substr($id3v1tag, 93, 4)); + $ParsedID3v1['comment'] = substr($id3v1tag, 97, 30); // can't remove nulls yet, track detection depends on them + $ParsedID3v1['genreid'] = ord(substr($id3v1tag, 127, 1)); + + // If second-last byte of comment field is null and last byte of comment field is non-null + // then this is ID3v1.1 and the comment field is 28 bytes long and the 30th byte is the track number + if (($id3v1tag{125} === "\x00") && ($id3v1tag{126} !== "\x00")) { + $ParsedID3v1['track'] = ord(substr($ParsedID3v1['comment'], 29, 1)); + $ParsedID3v1['comment'] = substr($ParsedID3v1['comment'], 0, 28); + } + $ParsedID3v1['comment'] = $this->cutfield($ParsedID3v1['comment']); + + $ParsedID3v1['genre'] = $this->LookupGenreName($ParsedID3v1['genreid']); + if (!empty($ParsedID3v1['genre'])) { + unset($ParsedID3v1['genreid']); + } + if (isset($ParsedID3v1['genre']) && (empty($ParsedID3v1['genre']) || ($ParsedID3v1['genre'] == 'Unknown'))) { + unset($ParsedID3v1['genre']); + } + + foreach ($ParsedID3v1 as $key => $value) { + $ParsedID3v1['comments'][$key][0] = $value; + } + + // ID3v1 data is supposed to be padded with NULL characters, but some taggers pad with spaces + $GoodFormatID3v1tag = $this->GenerateID3v1Tag( + $ParsedID3v1['title'], + $ParsedID3v1['artist'], + $ParsedID3v1['album'], + $ParsedID3v1['year'], + (isset($ParsedID3v1['genre']) ?
