Looks like this is also duplicate of previously assigned:
Name: CVE-2008-4409
Status: Candidate
URL: http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2008-4409
Final-Decision:
Interim-Decision:
Modified:
Proposed:
Assigned: 20081003
Category:
Reference: MLIST:[oss-security] 20081002 libxml2 "ampproblem" DoS
Reference: URL:http://openwall.com/lists/oss-security/2008/10/02/4
Reference: CONFIRM:http://bugzilla.gnome.org/show_bug.cgi?id=554660
libxml2 2.7.0 and 2.7.1 does not properly handle "predefined entities
definitions" in entities, which allows context-dependent attackers to
cause a denial of service (memory consumption and application crash),
as demonstrated by use of xmllint on a certain XML document, a
different vulnerability than CVE-2003-1564 and CVE-2008-3281.
CVE-2008-4409 is public on NVD site, CVE-2008-4422 in Gentoo BZ and
here... CVE-2008-4422 should probably be rejected.
