CVE-2026-112060 | BDVDB-2026-391302 Detail
RTMPDumplibrtmp
Description#
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.
Impact#
Per CVSS v3.1: confidentiality impact low, integrity impact low, availability impact high. Attack vector: network.
Weaknesses#
- CWE-787 Out-of-bounds Write
