[Frank-Z7]

Description

Dear developers,

We found the following heap buffer overflow bug on openjpeg, please confirm.

This bug is triggered when we use opj_decompress with the -t option and its argument set to 1.

The latest version v2.5.2 also has this vulnerability.

Version

# ./bin/opj_decompress -h
This is the opj_decompress utility from the OpenJPEG project.
It decompresses JPEG 2000 codestreams to various image formats.
It has been compiled against openjp2 library v2.5.2.

Reproduction

git clone https://github.com/uclouvain/openjpeg.git
cd openjpeg
cmake . -DCMAKE_BUILD_TYPE=Debug \
-DCMAKE_C_COMPILER=clang \
-DCMAKE_CXX_COMPILER=clang++ \
-DCMAKE_C_FLAGS="-fsanitize=address" \
-DCMAKE_CXX_FLAGS="-fsanitize=address"
make -j20

./bin/opj_decompress -i poc2openjpeg -o tmp.pnm -t 1

ASAN Log

./bin/opj_decompress -i poc2openjpeg -o tmp.pnm -t 1
