CVE-2024-8006

一、漏洞信息
 漏洞编号：[CVE-2024-8006](https://nvd.nist.gov/vuln/detail/CVE-2024-8006)
 漏洞归属组件：[libpcap](https://gitee.com/src-openeuler/libpcap)
 漏洞归属的版本：1.10.1,1.10.3,1.10.4,1.9.1
 CVSS V3.0分值：
  BaseScore：4.4 Medium
  Vector：CVSS：3.0/AV:L/AC:L/PR:H/UI:N/S:U/C:N/I:N/A:H
 漏洞简述：
  Remote packet capture support is disabled by default in libpcap.  When a user builds libpcap with remote packet capture support enabled, one of the functions that become available is pcap_findalldevs_ex().  One of the function arguments can be a filesystem path, which normally means a directory with input data files.  When the specified path cannot be used as a directory, the function receives NULL from opendir(), but does not check the return value and passes the NULL value to readdir(), which causes a NULL pointer derefence.

二、漏洞分析结构反馈
 影响性分析说明：
      CVE-2024-8006为libpcap Remote packet capture远程抓包功能的CVE，OpenEuler默认编译libpcap软件包不开启该功能，当用户编译libpcap软件包时启用远程抓包功能时涉及该漏洞，pcap_findalldevs_ex()函数中对文件系统路径的处理不当，当指定路径不能作为目录使用时，函数未检查opendir()的返回值并直接将NULL值传递给readdir()，从而导致空指针解引用。
