    Title
    librtmp (RTMPDump) through 2.6 Heap Out-of-Bounds Read via AMFProp_Decode
    Summary
    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.

    CVE-2026-112060 (GCVE-0-2026-112060)

    Vulnerability from nvd – Published: 2026-10-18 12:19 – Updated: 2026-10-18 12:19

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

    CVE-2026-112060 (GCVE-0-2026-112060)

    Vulnerability from cvelistv5 – Published: 2026-10-18 12:19 – Updated: 2026-10-18 12:19

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