Freshness: upstream tracker timestamp is available; use API updated time as primary recency signal.
CVE-2012-3456 medium priority: Ubuntu including 1 source packages (calligra), 6 status rows across 6 suites (hardy, lucid, natty, oneiric, precise, upstream): DNE 4, needs-triage 1, released 1.
Heap-based buffer overflow in the read function in filters/words/msword-odf/wv2/src/styles.cpp in the Microsoft import filter in Calligra 2.4.3 and earlier allows remote attackers to cause a denial of service (application crash) and possibly execute arbitrary code via a crafted ODF style in an ODF document. NOTE: this is the same vulnerability as CVE-2012-3455, but it was SPLIT by the CNA even though Calligra and KOffice share the same codebase.
