Name of the Vulnerable Software and Affected Versions curl versions prior to 7.84.0
Description A malicious server can serve excessive amounts of Set-Cookie: headers in a HTTP response to curl. This can cause subsequent HTTP requests to become larger than the internal threshold of 1048576 bytes, resulting in an error. The denial state might remain for as long as the same cookies are kept and haven't expired. Due to cookie matching rules, a server can set cookies that also match for other servers on the same second level domain, making it possible for a "sister server" to effectively cause a denial of service for a sibling site.
Recommendations For versions prior to 7.84.0, update to curl version 7.84.0 to resolve the issue. As a temporary workaround, consider restricting the use of the Set-Cookie: header or clearing excessive cookies to minimize the risk of exploitation.
