FFmpeg <= 8.0.1 Multiple Vulnerabilities

high Nessus Plugin ID 307356

Synopsis

The version of FFmpeg installed on the remote host is affected by multiple vulnerabilities.

Description

The version of FFmpeg installed on the remote host is 8.0.1 or earlier. It is, therefore, affected by multiple vulnerabilities:

- An out-of-bounds read in the read_global_param() function (libavcodec/av1dec.c) of FFmpeg v8.0.1 allows attackers to cause a Denial of Service (DoS) via a crafted input. (CVE-2026-30997)

- An improper resource deallocation and closure vulnerability in the tools/zmqsend.c component of FFmpeg v8.0.1 allows attackers to cause a Denial of Service (DoS) via supplying a crafted input file.
(CVE-2026-30998)

- A heap buffer overflow in the av_bprint_finalize() function of FFmpeg v8.0.1 allows attackers to cause a Denial of Service (DoS) via a crafted input. (CVE-2026-30999)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

See vendor advisory.
