A flaw was found in the opj2_decompress program in openjpeg2 2.4.0 in the
way it handles an input directory with a large number of files. When it
fails to allocate a buffer to store the filenames of the input directory,
it calls free() on an uninitialized pointer, leading to a segmentation
fault and a denial of service.
Bugs
Notes
| Author | Note |
|---|---|
| mdeslaur | this only affects the opj_decompress tool in the liopenjp2-tools universe package |
| ccdm94 | this issue does not affect package openjpeg (versions 1.x) as the code that causes the uninitialized pointer to be freed was introduced by PR https://github.com/uclouvain/openjpeg/pull/740. The code does contain memory leak problems, but since nothing is freed, the vulnerability in this case does not exist. |
