CVE-2024-22857

一、漏洞信息
 漏洞编号：[CVE-2024-22857](https://nvd.nist.gov/vuln/detail/CVE-2024-22857)
 漏洞归属组件：[zlog](https://gitee.com/src-openeuler/zlog)
 漏洞归属的版本：1.2.15
 CVSS V3.0分值：
  BaseScore：9.8 Critical
  Vector：CVSS：3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H
 漏洞简述：
  Heap based buffer flow in zlog v1.1.0 to v1.2.17 in zlog_rule_new().The size of record_name is MAXLEN_PATH(1024) + 1 but file_path may have data upto MAXLEN_CFG_LINE(MAXLEN_PATH*4) + 1. So a check was missing in zlog_rule_new() while copying the record_name from file_path + 1 which caused the buffer overflow. An attacker can exploit this vulnerability to overwrite the zlog_record_fn record_func function pointer to get arbitrary code execution or potentially cause remote code execution (RCE).
