Description
A flaw was found in curl. A remote malicious server can trigger a denial of service (DoS) in cookie handling by providing an overly long cookie name and value that exceeds curl's line-length limit when saved to a cookie file. Subsequent curl operations reading from this cookie file silently abort parsing upon encountering the oversized entry, causing all remaining valid cookies in the file to be ignored.
