CVE-2023-3446

一、漏洞信息
 漏洞编号：[CVE-2023-3446](https://nvd.nist.gov/vuln/detail/CVE-2023-3446)
 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：5.3 Medium
  Vector：CVSS：3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L
 漏洞简述：
  Issue summary: Checking excessively long DH keys or parameters may be very slow.Impact summary: Applications that use the functions DH_check(), DH_check_ex()or EVP_PKEY_param_check() to check a DH key or DH parameters may experience longdelays. Where the key or parameters that are being checked have been obtainedfrom an untrusted source this may lead to a Denial of Service.The function DH_check() performs various checks on DH parameters. One of thosechecks confirms that the modulus ( p  parameter) is not too large. Trying to usea very large modulus is slow and OpenSSL will not normally use a modulus whichis over 10,000 bits in length.However the DH_check() function checks numerous aspects of the key or parametersthat have been supplied. Some of those checks use the supplied modulus valueeven if it has already been found to be too large.An application that calls DH_check() and supplies a key or parameters obtainedfrom an untrusted source could be vulernable to a Denial of Service attack.The function DH_check() is itself called by a number of other OpenSSL functions.An application calling any of those other functions may similarly be affected.The other functions affected by this are DH_check_ex() andEVP_PKEY_param_check().Also vulnerable are the OpenSSL dhparam and pkeyparam command line applicationswhen using the  -check  option.The OpenSSL SSL/TLS implementation is not affected by this issue.The OpenSSL 3.0 and 3.1 FIPS providers are not affected by this issue.

二、漏洞分析结构反馈
 影响性分析说明：
  攻击者能利用openssl DH算法的漏洞对网络服务进行拒绝服务攻击服务端如果使用了DH_check、DH_check_ex、EVP_PKEY_param_check接口来对DH参数进行检查，当客户端传过来的DH为非法参数时，此时会消耗大量的计算资源，导致拒绝服务攻击openEuler-24.03-LTS-Next openEuler-24.03-LTS-SP1 openEuler-24.03-LTS基线版本已修复
