CVE-2023-6237

一、漏洞信息
 漏洞编号：[CVE-2023-6237](https://nvd.nist.gov/vuln/detail/CVE-2023-6237)
 漏洞归属组件：[compat-openssl11](https://gitee.com/src-openeuler/compat-openssl11)
 漏洞归属的版本：1.1.1m
 CVSS V3.0分值：
  BaseScore：5.9 Medium
  Vector：CVSS：3.0/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:N/A:H
 漏洞简述：
  Issue summary: Checking excessively long invalid RSA public keys may takea long time.Impact summary: Applications that use the function EVP_PKEY_public_check()to check RSA public keys may experience long delays. Where the key thatis being checked has been obtained from an untrusted source this may leadto a Denial of Service.When function EVP_PKEY_public_check() is called on RSA public keys,a computation is done to confirm that the RSA modulus, n, is composite.For valid RSA keys, n is a product of two or more large primes and thiscomputation completes quickly. However, if n is an overly large prime,then this computation would take a long time.An application that calls EVP_PKEY_public_check() and supplies an RSA keyobtained from an untrusted source could be vulnerable to a Denial of Serviceattack.The function EVP_PKEY_public_check() is not called from other OpenSSLfunctions however it is called from the OpenSSL pkey command lineapplication. For that reason that application is also vulnerable if usedwith the  -pubin  and  -check  options on untrusted data.The OpenSSL SSL/TLS implementation is not affected by this issue.The OpenSSL 3.0 and 3.1 FIPS providers are affected by this issue.

二、漏洞分析结构反馈
 影响性分析说明：
  在OpenSSL中发现了一个缺陷。当在RSA公共键中调用EVP_PKEY_PUBLIC_CHECK（）函数时，进行了计算以确认RSA模量N是复合的。对于有效的RSA键，N是两个或多个大型素数的产物，此计算很快完成。但是，如果n是一个很大的素数，则此计算需要很长时间。调用evp_pkey_public_check（）并提供从不受信任源获得的RSA密钥的应用程序可能容易受到拒绝服务攻击的影响。该漏洞只影响openssl3.0的版本
