Summary
ffmpeg security update
Details

FFmpeg is a complete and free Internet live audio and video broadcasting solution for Linux/Unix. It also includes a digital VCR. It can encode in real time in many formats including MPEG1 audio and video, MPEG4, h263, ac3, asf, avi, real, mjpeg, and flash.

Security Fix(es):

A heap-use-after-free in the mpeg_mux_write_packet function in libavformat/mpegenc.c of FFmpeg 4.2 allows to cause a denial of service (DOS) via a crafted avi file.(CVE-2020-21697)

Buffer Overflow vulnerability in FFmpeg 4.2 at convolution_y_10bit in libavfilter/vf_vmafmotion.c, which could let a remote malicious user cause a Denial of Service.(CVE-2020-22019)

Buffer Overflow vulnerability in FFmpeg 4.2 in the build_diff_map function in libavfilter/vf_fieldmatch.c, which could let a remote malicious user cause a Denial of Service.(CVE-2020-22020)

Buffer Overflow vulnerability in FFmpeg 4.2 at filter_edges function in libavfilter/vf_yadif.c, which could let a remote malicious user cause a Denial of Service.(CVE-2020-22021)

Buffer Overflow vulnerability exists in FFmpeg 4.2 in the config_input function at libavfilter/af_tremolo.c, which could let a remote malicious user cause a Denial of Service.(CVE-2020-22026)

A Denial of Service vulnerability exists in FFmpeg 4.2 due to a memory leak in avcodec_alloc_context3 at options.c.(CVE-2020-22037)

A Denial of Service vulnerability exists in FFmpeg 4.2 due to a memory leak in the ff_v4l2_m2m_create_context function in v4l2_m2m.c.(CVE-2020-22038)

A Denial of Service vulnerability exists in FFmpeg 4.2 due to a memory leak in the inavi_add_ientry function.(CVE-2020-22039)

A Denial of Service vulnerability exists in FFmpeg 4.2 due to a memory leak at the fifo_alloc_common function in libavutil/fifo.c.(CVE-2020-22043)

A Denial of Service vulnerability exists in FFmpeg 4.2 due to a memory leak in the filter_frame function in vf_tile.c.(CVE-2020-22051)

Integer Overflow vulnerability in function filter16_roberts in libavfilter/vf_convolution.c in Ffmpeg 4.2.1, allows attackers to cause a Denial of Service or other unspecified impacts.(CVE-2021-38090)

A reachable assertion in FFmpeg git-master commit N-113007-g8d24a28d06 allows attackers to cause a Denial of Service (DoS) via opening a crafted AAC file.(CVE-2025-22919)

Drag nodes to arrange them. Double-click a related vulnerability to open it, or a source to visit its link. The Physics button on the left tunes the layout and the simulation; the legend at the bottom left hides or shows nodes by kind and by sighting type.

Forecast uses a logistic model when the trend is rising, or an exponential decay model when the trend is falling. Fitted via linearized least squares.

Sightings

Author Source Type Date Other

Nomenclature

  • Seen: The vulnerability was mentioned, discussed, or observed by the user.
  • Confirmed: The vulnerability has been validated from an analyst's perspective.
  • Published Proof of Concept: A public proof of concept is available for this vulnerability.
  • Exploited: The vulnerability was observed as exploited by the user who reported the sighting.
  • Patched: The vulnerability was observed as successfully patched by the user who reported the sighting.
  • Not exploited: The vulnerability was not observed as exploited by the user who reported the sighting.
  • Not confirmed: The user expressed doubt about the validity of the vulnerability.
  • Not patched: The vulnerability was not observed as successfully patched by the user who reported the sighting.

How durations are calculated

Following the VTEM framework (Black Hat USA 2015), time to patch starts when the vendor or a coordinator was informed, total time to patch at discovery, and disclosure to patch at public disclosure; vendor response time runs from the report to its acknowledgement. Time to exploit and time unpatched start at the earliest discovery or report, falling back to public disclosure. Unpatched time ends at the first recorded patch, or the calculation time when no patch is recorded. Exploitation to patch shows the interval between those two events; a published proof of concept is a public exploit, not exploitation.

Each result shows its source dates. A negative interval means the end event came first; when date-only inputs leave the order open, the result says so. Date-only inputs are approximate. The earliest evidence wins: KEV report dates and sightings are labelled as such. Records describing another vulnerability are listed but never calculated from, and a PoC alone does not establish exploitation. Missing patch evidence does not prove that no patch exists. Filters below change the event list only.
