CVE-2026-112060
Description
A flaw was found in rtmpdump. A malicious Real-Time Messaging Protocol (RTMP) server or an attacker intercepting network communications can exploit this issue by transmitting crafted Action Message Format (AMF3) data with oversized string lengths. Because the library fails to properly handle decoding errors, this triggers out-of-bounds memory reads and writes. Consequently, an attacker can cause a Denial of Service (DoS) through application crashes or expose sensitive memory contents.
Statement

Availability
Technical Impact: DoS: Crash, Exit, or Restart
Attempting to access out-of-range, invalid, or unauthorized memory could cause the product to crash.
