一、漏洞信息

漏洞编号：[CVE-2021-3446](https://nvd.nist.gov/vuln/detail/CVE-2021-3446)

漏洞归属组件：libtpms

漏洞归属的版本：0.7.3

CVSS V3.0分值：

BaseScore：5.5 Medium

Vector：CVSS：3.0/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N

漏洞简述：

A flaw was found in libtpms in versions before 0.8.2. The commonly used integration of libtpms with OpenSSL contained a vulnerability related to the returned IV (initialization vector) when certain symmetric ciphers were used. Instead of returning the last IV it returned the initial IV to the caller, thus weakening the subsequent encryption and decryption steps. The highest threat from this vulnerability is to data confidentiality.
