CVE-2026-112061— librtmp (RTMPDump) through 2.6 Heap Out-of-Bounds Read via AMFProp_Decode

Quick assessment

Affected
RTMPDump librtmp
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.

librtmp（即 RTMPDump）2.6 及更早版本中存在一个堆越界读取漏洞，该漏洞位于 AMFProp_Decode 函数中。该函数在检查剩余字节数是否不少于四个之前，就会读取 AMF0 严格数组（strict-array）的元素计数。攻击者控制的恶意 RTMP 服务器或中间人可发送一个以严格数组类型字节结尾、但尾部不足四个字节的 AMF0 消息体，从而导致客户端崩溃。
