Ubuntu 23.10 USN-6535-1 moderate: curl handling cookie threats

ubuntu

December 6, 2023

Several security issues were fixed in curl.

Summary

Several security issues were fixed in curl.

Software Description:

- curl: HTTP, HTTPS, and FTP client and client libraries

Details:

Harry Sintonen discovered that curl incorrectly handled mixed case cookie

domains. A remote attacker could possibly use this issue to set cookies

that get sent to different and unrelated sites and domains.

(CVE-2023-46218)

Maksymilian Arciemowicz discovered that curl incorrectly handled long file

names when saving HSTS data. This could result in curl losing HSTS data,

and subsequent requests to a site would be done without it, contrary to

expectations. This issue only affected Ubuntu 23.04 and Ubuntu 23.10.

(CVE-2023-46219)
