Heap-based buffer overflow in the read function in filters/words/msword-odf/wv2/src/styles.cpp in the Microsoft import filter in KOffice 2.3.3 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-2012-3456, but it was SPLIT by the CNA even though Calligra and KOffice share the same codebase.
結論預警: CVE-2012-3455 綜合評估為中等風險（60.7/100）：CVSS 技術影響為高級，利用機率偏高（EPSS 5.29%，百分位 91%） 核心證據: EPSS 顯示該漏洞近期被利用的可能性處於高位。 強制指令: 被利用機率偏高—請盤點暴露面並優先安排修補。
