| Package | Affected versions | Patched versions |
|---|---|---|
| php | = 5.3.7= 5.3.8 |
The is_a function in PHP 5.3.7 and 5.3.8 triggers a call to the __autoload function, which makes it easier for remote attackers to execute arbitrary code by providing a crafted URL and leveraging potentially unsafe behavior in certain PEAR packages and custom autoloaders.
