Affected
Apache Software Foundation Apache Thrift
Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.
Apache Thrift Go 绑定中存在不受控制的递归漏洞。 Go 传输层在处理缓冲区帧读取时，当该帧未提供有效载荷字节时，会继续读取下一个帧并再次调用 函数，而不是进行循环处理。这种机制在特定情况下会导致无限递归：在 中，对等端可以构造一个大小为 0（声明帧大小为 0）的帧，占据 4 个字节；在 中，对等端可以构造一个填满帧的头部块，占据 18 个字节。由于缺乏对递归深度的限制，最终会耗尽 Go 运行时栈空间，导致出现无法被 捕获的致命错误（fatal error），从而使整个进程崩溃。 此问题影响 Apac

Vulnerability Title
Apache Thrift: TFramedTransport and THeaderTransport re-enter Read once per frame that carries no payload (Go)
Source: CVE Program / CVE List V5
Vulnerability Description
Uncontrolled Recursion vulnerability in Apache Thrift go bindings.
Both Go transports satisfy a read out of a buffered frame and, when that frame yields no payload bytes, read the next frame and call `Read` again instead of looping. A peer produces such a frame for 4 bytes in `TFramedTransport` (a declared size of zero) or 18 bytes in `THeaderTransport` (a header block that fills the frame), so nothing bounds the depth. The Go stack limit is reached as a `fatal error`, which `recover()` cannot catch, so the whole process dies.
This issue affects Apache Thrift: before 0.25.0.
Users are recommended to upgrade to version 0.25.0, which fixes the issue.
