Description

This flaw allows a malicious HTTP server to set "super cookies" in curl that

are then passed back to more origins than what is otherwise allowed or

possible. This allows a site to set cookies that then would get sent to

different and unrelated sites and domains.

It could do this by exploiting a mixed case flaw in curl's function that

verifies a given cookie domain against the Public Suffix List (PSL). For

example a cookie could be set with `domain=co.UK` when the URL used a lower

case hostname `curl.co.uk`, even though `co.uk` is listed as a PSL domain.

Solution(s)

  • oracle-linux-upgrade-curl
  • oracle-linux-upgrade-curl-minimal
  • oracle-linux-upgrade-libcurl
  • oracle-linux-upgrade-libcurl-devel
  • oracle-linux-upgrade-libcurl-minimal
