Under most + conditions (i.e., when the --enable-using-memchecker option is NOT + used), this would result in a small memory leak and and infinite loop + and abort when shutting down the library. The infinite loop would be + due to the "free list" package not being able to clear its resources + so the library couldn't shut down. When the "using a memory checker" + option is used, the free lists are disabled so there is just a memory + leak with no abort on library shutdown. + + The chunk index resources are now correctly cleaned up when reading + misparsed files and valgrind confirms no memory leaks. + + - Fixed an assertion in a previous fix for CVE-2016-4332 + + An assert could fail when processing corrupt files that have invalid + shared message flags (as in CVE-2016-4332). + + The assert statement in question has been replaced with pointer checks + that don't raise errors. Since the function is in cleanup code, we do + our best to close and free things, even when presented with partially + initialized structs. + + Fixes CVE-2016-4332 and HDFFV-9950 (confirmed via the cve_hdf5 repo) + - Fixed a file space allocation bug in the parallel library for chunked datasets |
