+Subject: [PATCH 10/11] gtlspassword: Forbid very long TLS passwords
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+The public API `g_tls_password_set_value_full()` (and the vfunc it
+invokes) can only accept a `gssize` length. Ensure that nul-terminated
+strings passed to `g_tls_password_set_value()` can’t exceed that length.
+Use `g_memdup2()` to avoid an overflow if they’re longer than
+`G_MAXUINT` similarly.
+
+Signed-off-by: Philip Withnall <pwithnall@endlessos.org>
+Helps: #2319
