CVE-2018-15671

An issue was discovered in the HDF HDF5 1.10.2 library. Excessive stack
consumption has been detected in the function H5P__get_cb() in H5Pint.c during
an attempted parse of a crafted HDF file. This results in denial of service.

QA REPRODUCER:

h5dump stackoverflow_H5P__get_cb

will only terminate after running long

(endless recursion exhausting stack)
Comment 3 Egbert Eich 2022-05-05 10:41:57 UTC 
No upstream fix is available, yet.
Comment 4 Egbert Eich 2022-09-05 12:37:47 UTC 
This is not really a vulnerability.
- This problem happens only with a hand-crafted file.
- The stack will grow in size until the program is terminated, however no illegal or   
  'out-of-bound' accesses can be detected.
- Problem can be mitigated by setting an appropriate ulimit when processing hdf5 
  files from uncertain origin.
Comment 5 Gabriele Sonnu 2022-09-07 11:18:35 UTC 
SUSE will not provide a fix for this issue since the risk to our customers posed by this is negligible.
