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

This page contains facts from public vulnerability sources. Check the original advisory before updating.

librtmp (RTMPDump) through 2.6 contains a heap out-of-bounds read vulnerability in AMFProp_Decode that reads an AMF0 strict-array element count before checking that four bytes remain. A malicious RTMP server or man in the middle can send an AMF0 body ending with a strict-array type byte and fewer than four trailing bytes to crash the client.
