一、漏洞信息
 漏洞编号：[CVE-2024-33601](https://nvd.nist.gov/vuln/detail/CVE-2024-33601)
 漏洞归属组件：[glibc](https://gitee.com/src-openeuler/glibc)
 漏洞归属的版本：2.28,2.31,2.34,2.35,2.36,2.38
 CVSS V2.0分值：
  BaseScore：0.0 Low
  Vector：CVSS：2.0/
 漏洞简述：
  nscd: netgroup cache may terminate daemon on memory allocation failureThe Name Service Cache Daemon s (nscd) netgroup cache uses xmalloc orxrealloc and these functions may terminate the process due to a memoryallocation failure resulting in a denial of service to the clients.  Theflaw was introduced in glibc 2.15 when the cache was added to nscd.This vulnerability is only present in the nscd binary.

二、漏洞分析结构反馈
 影响性分析说明：
          nscd:网络组缓存可能会在内存分配失败时终止守护进程Name Service Cache Daemon(nscd)的网络组缓存使用xmalloc或xrealloc，这些函数可能会由于内存分配失败而终止进程，从而导致对客户端的拒绝服务。该漏洞是在glibc 2.15中向nscd添加缓存时引入的。此漏洞仅存在于nscd二进制文件中；
