CVE-2024-47835

一、漏洞信息
 漏洞编号：[CVE-2024-47835](https://nvd.nist.gov/vuln/detail/CVE-2024-47835)
 漏洞归属组件：[gstreamer1-plugins-base](https://gitee.com/src-openeuler/gstreamer1-plugins-base)
 漏洞归属的版本：1.16.2,1.18.4,1.19.3,1.20.3,1.22.5,1.24.0
 CVSS V3.0分值：
  BaseScore：0.0 None
  Vector：CVSS：3.0/
 漏洞简述：
  GStreamer is a library for constructing graphs of media-handling components. A null pointer dereference vulnerability has been detected in the parse_lrc function within gstsubparse.c. The parse_lrc function calls strchr() to find the character  ]  in the string line. The pointer returned by this call is then passed to g_strdup(). However, if the string line does not contain the character  ] , strchr() returns NULL, and a call to g_strdup(start + 1) leads to a null pointer dereference. This vulnerability is fixed in 1.24.10.
