🛡️ OESA-2026-3287 — ffmpeg
Description
ffmpeg security update
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):
Buffer Overflow vulnerability exists in FFmpeg 4.1 via apng_do_inverse_blend in libavcodec/pngenc.c, which could let a remote malicious user cause a Denial of Service(CVE-2020-21041)
A heap-based Buffer Overflow vulnerabililty exists in FFmpeg 4.2 in filter_frame at libavfilter/vf_bitplanenoise.c, which might lead to memory corruption and other potential consequences.(CVE-2020-22023)
Buffer Overflow vulnerability in FFmpeg 4.2 at the lagfun_frame16 function in libavfilter/vf_lagfun.c, which could let a remote malicious user cause Denial of Service.(CVE-2020-22024)
Buffer Overflow vulnerability exists in FFmpeg 4.2 in filter_vertically_8 at libavfilter/vf_avgblur.c, which could cause a remote Denial of Service.(CVE-2020-22028)
A Heap-based Buffer Overflow vulnerability exists in FFmpeg 4.2 at libavfilter/vf_w3fdif.c in filter16_complex_low, which might lead to memory corruption and other potential consequences.(CVE-2020-22031)
A heap-based Buffer Overflow vulnerability exists FFmpeg 4.2 at libavfilter/vf_edgedetect.c in gaussian_blur, which might lead to memory corruption and other potential consequences.(CVE-2020-22032)
A heap-based Buffer Overflow vulnerability exists in FFmpeg 4.2 in get_block_row at libavfilter/vf_bm3d.c, which might lead to memory corruption and other potential consequences.(CVE-2020-22035)
A heap-based Buffer Overflow vulnerability exists in FFmpeg 4.2 in filter_intra at libavfilter/vf_bwdif.c, which might lead to memory corruption and other potential consequences.(CVE-2020-22036)
A Denial of Service vulnerability exists in FFmpeg 4.2 idue to a memory leak in the v_frame_alloc function in frame.c.(CVE-2020-22040)
A Denial of Service vulnerability exists in FFmpeg 4.2 due to a memory leak in the av_buffersrc_add_frame_flags function in buffersrc.(CVE-2020-22041)
A Denial of Service vulnerability exists in FFmpeg 4.2 due to a memory leak in the ff_frame_pool_get function in framepool.c.(CVE-2020-22048)
A Denial of Service vulnerability exists in FFmpeg 4.2 due to a memory leak in the config_input function in af_acrossover.c.(CVE-2020-22056)
decode_frame in libavcodec/exr.c in FFmpeg 4.3.1 has an out-of-bounds write because of errors in calculations of when to perform memset zero operations.(CVE-2020-35965)
A heap-buffer-overflow write exists in jpeg2000dec FFmpeg which allows an attacker to potentially gain remote code execution or cause denial of service via the channel definition cdef atom of JPEG2000.(CVE-2025-9951)
How this vulnerability can be exploited
This issue can be reached over the network, attack complexity is low, an attacker needs no privileges on the target. A user must be tricked into taking some action. The scope is unchanged, so the impact stays within the vulnerable component. Rated impact: confidentiality high, integrity high, availability high.
