CVE-2025-4575— OpenSSL 安全漏洞

The x509 application adds trusted use instead of rejected use

Issue summary: Use of -addreject option with the openssl x509 application adds a trusted use instead of a rejected use for a certificate. Impact summary: If a user intends to make a trusted certificate rejected for a particular use it will be instead marked as trusted for that use. A copy & paste error during minor refactoring of the code introduced this issue in the OpenSSL 3.5 version. If, for example, a trusted CA certificate should be trusted only for the purpose of authenticating TLS servers but not for CMS signature verification and the CMS signature verification is intended to be marked as rejected with the -addreject option, the resulting CA certificate will be trusted for CMS signature verification purpose instead. Only users which use the trusted certificate format who use the openssl x509 command line application to add rejected uses are affected by this issue. The issues affecting only the command line application are considered to be Low severity. The FIPS modules in 3.5, 3.4, 3.3, 3.2, 3.1 and 3.0 are not affected by this issue. OpenSSL 3.4, 3.3, 3.2, 3.1, 3.0, 1.1.1 and 1.0.2 are also not affected by this issue.

OpenSSL 安全漏洞

OpenSSL是OpenSSL团队的一个开源的能够实现安全套接层（SSLv2/v3）和安全传输层（TLSv1）协议的通用加密库。该产品支持多种加密算法，包括对称密码、哈希算法、安全散列算法等。 OpenSSL存在安全漏洞，该漏洞源于openssl x509命令中-addreject选项错误标记证书用途，可能导致信任错误。
