一、漏洞信息
 漏洞编号：[CVE-2024-50382](https://nvd.nist.gov/vuln/detail/CVE-2024-50382)
 漏洞归属组件：[botan2](https://gitee.com/src-openeuler/botan2)
 漏洞归属的版本：2.19.1,2.19.3
 CVSS V3.0分值：
  BaseScore：5.9 Medium
  Vector：CVSS：3.0/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:N/A:N
 漏洞简述：
  Botan before 3.6.0, when certain LLVM versions are used, has compiler-induced secret-dependent control flow in lib/utils/ghash/ghash.cpp in GHASH in AES-GCM. There is a branch instead of an XOR with carry. This was observed for Clang in LLVM 15 on RISC-V.
