+Subject: [PATCH] socks: return error if hostname too long for remote resolve
+
+Prior to this change the state machine attempted to change the remote
+resolve to a local resolve if the hostname was longer than 255
+characters. Unfortunately that did not work as intended and caused a
+security issue.
+
+Upstream-Status: Backport [https://github.com/curl/curl/commit/fb4415d8aee6c1045be932a34fe6107c2f5ed147]

+CVE: CVE-2023-38545
