+Subject: [PATCH] Check for overflow when calculating on-disk attribute data
+ size
+
+Bogus sizes in this test case causes the on-disk data size
+calculation in H5O_attr_decode() to overflow so that the
+calculated size becomes 0. This causes the read to overflow
+and h5dump to segfault.
+
+CVE: CVE-2021-37501
+
+Upstream-Status: Backport [https://github.com/HDFGroup/hdf5/commit/b16ec83d4bd79f9ffaad85de16056419f3532887]
