From 960f9a9243282da838da655d03bb34261e300498 Mon Sep 17 00:00:00 2001 From: Quentin Schulz Date: Mon, 2 Jan 2023 15:39:34 +0100 Subject: cairo: fix CVE patches assigned wrong CVE number CVE-2019-6461 and CVE-2019-6462 are fixed, but the reporting is incorrect as the patch for CVE-2019-6461 is actually for CVE-2019-6462 and vice-versa. This swaps both files and edit the CVE field to report the correct identifier.
