漏洞描述信息
在Fluent Bit 3.1.9中发现了一个问题。当OpenTelemetry输入插件正在运行并监听某个IP地址和端口时,可以通过发送一个包含Content-Length: 0的包来使服务器崩溃。当Content-Length为0时,不正确的处理方式允许具有访问该端点权限的用户执行远程拒绝服务攻击。崩溃的原因是在将0(来自Content-Length)传递给函数cfl_sds_len时发生了一个空指针解引用,该函数试图将一个空指针转换为struct cfl_sds。这与opentelemetry_prot.c文件中的process_payload_traces_proto_ng()函数有关。

漏洞描述信息
An issue was discovered in Fluent Bit 3.1.9. When the OpenTelemetry input plugin is running and listening on an IP address and port, one can send a packet with Content-Length: 0 and it crashes the server. Improper handling of the case when Content-Length is 0 allows a user (with access to the endpoint) to perform a remote Denial of service attack. The crash happens because of a NULL pointer dereference when 0 (from the Content-Length) is passed to the function cfl_sds_len, which in turn tries to cast a NULL pointer into struct cfl_sds. This is related to process_payload_traces_proto_ng() at opentelemetry_prot.c.
