Security Bulletin: WML CE: SQLite through 3.32.0 has an integer overflow in sqlite3_str

Security Bulletin

Summary

Tensorflow uses SQLite as its embedded SQL database engine. SQLite through 3.32.0 has an integer overflow in sqlite3_str_vappendf in printf.c so it has been updated to 3.32.3 in WML CE.

Vulnerability Details

CVEID: CVE-2020-13435
DESCRIPTION: SQLite is vulnerable to a denial of service, caused by flaw in the sqlite3ExprCodeTarget function in expr.c. By sending a specially-crafted request, a remote attacker could exploit this vulnerability to cause a segmentation fault.
CVSS Base score: 7.5
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/182406 for the current score.
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H)

CVEID: CVE-2020-13434
DESCRIPTION: SQLite is vulnerable to a stack-based buffer overflow, caused by an integer overflow in the sqlite3_str_vappendf function. 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: https://exchange.xforce.ibmcloud.com/vulnerabilities/182405 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)
