In OpenSSL 1.1.0 before 1.1.0c, applications parsing invalid CMS structures can crash with a NULL pointer dereference. This is caused by a bug in the handling of the ASN.1 CHOICE type in OpenSSL 1.1.0 which can result in a NULL value being passed to the structure callback if an attempt is made to free certain invalid encodings. Only CHOICE structures using a callback which do not handle NULL value are affected.
結論預警: CVE-2016-7053 綜合評估為中等風險(64.4/100):CVSS 技術影響為高級,利用機率偏高(EPSS 21.68%,百分位 97%) 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。
