Security Bulletin
This security bulletin contains information about 3 vulnerabilities.
1) Division by zero
EUVDB-ID: #VU23188
Risk: Low
CVSSv4.0: 2 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N/E:P/U:Clear]
CVE-ID: CVE-2019-16168
CWE-ID:
CWE-369 - Divide By Zero
Exploit availability: Yes
DescriptionThe 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.
Update the affected packages.
