CVE-2022-43255: Memory Leak in gf_odf_new_iod odf/odf_code.c:415 · Issue #2285 · gpac/gpac

Libde265 v1.0.8 was discovered to contain a segmentation violation via apply_sao_internal<unsigned short> in sao.cc. This vulnerability allows attackers to cause a Denial of Service (DoS) via a crafted video file.

CVE-2022-43240: Heap-buffer-overflow in sse-motion.cc: ff_hevc_put_hevc_qpel_h_2_v_1_sse · Issue #335 · strukturag/libde265

Libde265 v1.0.8 was discovered to contain a heap-buffer-overflow vulnerability via put_unweighted_pred_16_fallback in fallback-motion.cc. This vulnerability allows attackers to cause a Denial of Service (DoS) via a crafted video file.

**Description**

Heap-buffer-overflow (/libde265/build/libde265/liblibde265.so+0x145b6b) in put\_unweighted\_pred\_16\_fallback(unsigned short\*, long, short const\*, long, int, int, int)

**Version**

$ ./dec265 -h
 dec265  v1.0.8
--------------
usage: dec265 \[options\] videofile.bin
The video file must be a raw bitstream, or a stream with NAL units (option -n).

options:
  -q, --quiet       do not show decoded image
  -t, --threads N   set number of worker threads (0 - no threading)
  -c, --check-hash  perform hash check
  -n, --nal         input is a stream with 4-byte length prefixed NAL units
  -f, --frames N    set number of frames to process
  -o, --output      write YUV reconstruction
  -d, --dump        dump headers
  -0, --noaccel     do not use any accelerated code (SSE)
  -v, --verbose     increase verbosity level (up to 3 times)
  -L, --no-logging  disable logging
  -B, --write-bytestream FILENAME  write raw bytestream (from NAL input)
  -m, --measure YUV compute PSNRs relative to reference YUV
  -T, --highest-TID select highest temporal sublayer to decode
      --disable-deblocking   disable deblocking filter
      --disable-sao          disable sample-adaptive offset filter
  -h, --help        show help

**Replay**

git clone https://github.com/strukturag/libde265.git
cd libde265
mkdir build
cd build
cmake ../ -DCMAKE\_CXX\_FLAGS="\-fsanitize=address"
make -j$(nproc)
