6.1.6Jun 20, 2026 · 3 months agoFrom commit messages

n6.1.6

Fixed 10

avformat/dashdec, dashenc, hlsenc, and demux now respect io_open set in AVFormatContext and use correct close function for custom io.
avformat/oggparsecelt bounded extra_headers to avoid an effectively infinite loop.
avcodec/hdrdec fixed pixel count decrement in RLE decompress loop.
avcodec/hevc limited missing-ref fill to coded planes and tightened sh_num_tiles_in_slice_minus1 upper bound.
avformat issues including Wave unaligned metadata chunks, vividas misaligned access, rtpenc_aac small packets, rtpenc_xiph max payload underflow, ty rec_size check, hls url_offset and size validation, and hls TIME-OFFSET validation.
avcodec issues including diracdec mctmp buffer size and edge_emu_buffer overflow, g2meet stack size, jpeg2000dec mask computation and header variables, magicyuv MEDIAN slices and interlaced slice-height checks, h264_slice chroma-width underflow, vorbisdsp inverse coupling, and various overflow and bounds checks in cook, on2avc, truespeech, agm, rv10, and rv34 decoders.
avfilter issues including boxblur off-by-one errors, af_join buffer dedup use-after-free, and vf_drawtext pixel_mode checks and glyph memory management.
avformat/ftp now rejects CR/LF in URL path and non-printable ASCII characters to prevent command injection.

7.1.5Jun 20, 2026 · 3 months agoFrom commit messages

n7.1.5

Fixed 10

avformat/dashdec, dashenc, hlsenc: respect io_open set in AVFormatContext and use correct close function for custom io.
avformat/demux: use correct close function for custom io.
avformat/oggparsecelt and oggparsevorbis: bound extra_headers and prevent integer overflow when summing header lengths.
avformat/mov_chan: keep the layout untouched on chan/chnl box failure and don't abort on unsupported or invalid chnl boxes.
avcodec/vvc: multiple fixes including not using large array on stack, checking frame to be non-NULL, ensuring every CTU belongs to a slice, returning error if CTU size > 128, adding support for output_corrupt/showall flags, and fixing issues with inverse LMCS idx, slice map construction, subpicture overlaps, divide-by-zero in LMCS param derivation, and error handling.
avcodec/cbs_h266: stricter validation for subpicture's max width and height, fix wrong condition for chroma MTT depth in PH, tighten sh_num_tiles_in_slice_minus1 upper bound, and fix pps_exp_slice_height_in_ctus_minus1 range.
avcodec/hdrdec: fix pixel count decrement in RLE decompress loop.
avformat/mov: fix negative index given to can_seek_to_key_sample().
avformat and avcodec: multiple security and stability fixes including bounds checks in oggparsevorbis, rtpenc_aac, rtpenc_xiph, hls, soxdec, mxfdec, cook, ftp (CR/LF and IAC character injection prevention), matroskadec, iamf_parse, jpeglsdec, rtmppkt, magicyuv, h264_slice, aac/aacdec, vc2enc_dwt, fastaudio, and adpcm.
avfilter/drawtext: prevent double-free and glyph caching issues, and plug error-path leaks in measure_text/draw_text.
