Description Andrej Nemec 2017-12-12 05:01:25 EST 
In HDF5 1.10.1, there is an out of bounds write vulnerability in the function H5G__ent_decode_vec in H5Gcache.c in libhdf5.a. For example, h5dump would crash or possibly have unspecified other impact someone opens a crafted hdf5 file.

Red Hat Product Security has rated this issue as having Low security impact. This issue is not currently planned to be addressed in future updates. For additional information, refer to the Issue Severity Classification: https://access.redhat.com/security/updates/classification/.

Whilst the package shipped with Red Hat OpenStack contains the vulnerable code, the packages that use HDF5 do not expose the vulnerable functionality.
