Stefan Esser has reported a vulnerability in cURL/libcURL, which has an unknown impact.
The vulnerability is caused due to an off-by-one error when parsing an URL that is longer than 256 bytes. By using a specially crafted URL, a two-byte overflow is reportedly possible. This may be exploited to corrupt memory allocation structures. The vulnerability is reportedly exploitable only via a direct request to cURL and not via a redirect.
The vulnerability has been reported in version 7.15.0 and prior.
NOTE: The actual impact of this vulnerability depends on the application (e.g. PHP) that uses the cURL library.
