CVE-2020-15195 (GCVE-0-2020-15195)

Vulnerability from cvelistv5

Published

2020-09-25 18:40

Modified

2024-08-04 13:08

Severity ?

8.5 (High) - CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:C/C:H/I:H/A:H

CWE

CWE-119 - {"":"Improper Restriction of Operations within the Bounds of a Memory Buffer"}
CWE-122 - {"":"Heap-based Buffer Overflow"}

Summary

In Tensorflow before versions 1.15.4, 2.0.3, 2.1.2, 2.2.1 and 2.3.1, the implementation of `SparseFillEmptyRowsGrad` uses a double indexing pattern. It is possible for `reverse_index_map(i)` to be an index outside of bounds of `grad_values`, thus resulting in a heap buffer overflow. The issue is patched in commit 390611e0d45c5793c7066110af37c8514e6a6c54, and is released in TensorFlow versions 1.15.4, 2.0.3, 2.1.2, 2.2.1, or 2.3.1.
