Security Bulletin

This security bulletin contains information about 5 vulnerabilities.

1) Division by zero

EUVDB-ID: #VU23188

Risk: Low

CVSSv3.1: 3.8 [CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:L/E:U/RL:O/RC:C]

CVE-ID: CVE-2019-16168

CWE-ID: CWE-369 - Divide By Zero

Exploit availability: Yes

Description

The vulnerability allows a remote attacker to perform a denial of service attack.

The vulnerability exists due to a division by zero error within the whereLoopAddBtreeIndex in sqlite3.c due to improper input validation in the sqlite_stat1 sz field. A remote attacker can pass specially crafted data to the application, trigger division by zero error and crash the vulnerable application.

Mitigation

Install updates from vendor's website.
