Subject: [PATCH] conf: Don't format http cookies unless
 VIR_DOMAIN_DEF_FORMAT_SECURE is used

Starting with 3b076391befc3fe72deb0c244ac6c2b4c100b410
(v6.1.0-122-g3b076391be) we support http cookies. Since they may contain
somewhat sensitive information we should not format them into the XML
unless VIR_DOMAIN_DEF_FORMAT_SECURE is asserted.

(cherry picked from commit a5b064bf4b17a9884d7d361733737fb614ad8979)

CVE-2020-14301
Message-Id: <592a0b594666f580e743b6bd2b4ddccbd1e0cc7c.1592914898.git.pkrempa@redhat.com>
