Hi Jenkins Advisory from 2014-02-14[1] mentions several security fixes, where for SECURITY-76 and SECURITY-88 CVE-2013-5573 was assigned.

Regards, Salvatore
It looks to me as though at least some of these issues definitely need CVE IDs assigned. I reported SECURITY-105, and it is my opinion that this flaw needs a separate CVE ID to CVE-2013-7285. The Jenkins patch blocks DynamicProxyConverter from the Jenkins wrapper class XStream2, without changing the XStream library at all. This implements a less-general solution than the XStream patch for CVE-2013-7285, and the patch applies to a completely separate codebase (i.e. Jenkins itself,not XStream). Therefore it is my understanding that this flaw as it affects Jenkins qualifies for a unique CVE ID. When reporting this flaw to upstream, the Jenkins engineers agreed that it qualified for a unique CVE ID, and I offered to assign a CVE ID from the Red Hat CNA. This offer was refused, but then the advisory was released without a unique CVE ID, which is puzzling indeed. Could someone from MITRE please weigh in and assign CVE IDs as appropriate for these flaws? Thanks -- David Jorm / Red Hat Security Response Team
