CVE-2026-112060

librtmp (RTMPDump) through 2.6 Heap Out-of-Bounds Write via AMF3_Decode

6.1 Medium

librtmp in RTMPDump through 2.6 contains an out-of-bounds read and heap out-of-bounds write vulnerability because AMF3_Decode ignores AMF3 property decode failures. Malicious RTMP servers or man-in-the-middle attackers can send oversized AMF3 string lengths, and with the token option DecodeTEA corrupts heap memory and leaks heap bytes.
