CVE-2025-9086 found in deb/debian/curl@8.14.1-2
Important
Risk: 2.12 (Low)
CVSS: 7.5
Description
- A cookie is set using the
securekeyword forhttps://target - curl is redirected to or otherwise made to speak with
http://target(same hostname, but using clear text HTTP) using the same cookie set - The same cookie name is set - but with just a slash as path (
path='/'). Since this site is not secure, the cookie should just be ignored. - A bug in the path comparison logic makes curl read outside a heap buffer boundary
The bug either causes a crash or it potentially makes the comparison come to the wrong conclusion and lets the clear-text site override the contents of the secure cookie, contrary to expectations and depending on the memory contents immediately following the single-byte allocation that holds the path.
The presumed and correct behavior would be to plainly ignore the second set of the cookie since it was already set as secure on a secure host so overriding it on an insecure host should not be okay.
