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.
