Security Bulletin: WML CE: TensorFlow: In SQLite before 3.32.3, select.c mishandles query-flattener optimization

Security Bulletin


In SQLite before 3.32.3, select.c mishandles query-flattener optimization, leading to a multiSelectOrderBy heap overflow because of misuse of transitive properties for constant propagation. TensorFlow in WML CE uses SQLite as its embedded SQL database engine.

Vulnerability Details

CVEID:   CVE-2020-15358
DESCRIPTION:   SQLite is vulnerable to a heap-based buffer overflow, caused by improper bounds checking by the mishandling of query-flattener optimization in select.c. By sending a specially-crafted request, a remote attacker could overflow a buffer and execute arbitrary code on the system.
CVSS Base score: 9.8
CVSS Temporal Score: See: for the current score.
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H)

Affected Products and Versions

Affected Product(s)Version(s)
IBM Watson Machine Learning Community Edition1.6.2

TensorFlow has been rebuild to include SQLite 3.32.3.

Workarounds and Mitigations

Tensorflow must be updated.

For the GPU enabled version:

  conda update tensorflow-gpu

For the non GPU enabled version:
