cURL/libcURL CVE-2018-1000120 Buffer Overflow Vulnerability

cURL/libcURL is prone to a buffer-overflow vulnerability because it fails to adequately bounds-check user-supplied data before copying it into an insufficiently sized buffer.

Attackers can exploit this issue to cause denial-of-service conditions. Due to the nature of this issue, arbitrary code execution may be possible, but this has not been confirmed.

cURL/libcURL 7.12.3 through 7.58.0 are vulnerable.
