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.
2) Integer overflow (CVE-ID: CVE-2020-13434)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to integer overflow within the sqlite3_str_vappendf() function in printf.c. A remote attacker can pass specially crafted data to the application, trigger integer overflow and crash the application.
3) Use-after-free (CVE-ID: CVE-2020-13630)
The vulnerability allows a remote attacker to compromise vulnerable system.
The vulnerability exists due to a use-after-free error within the fts3EvalNextRow() function in ext/fts3/fts3.c. A remote attacker can pass specially crafted data to application, trigger a use-after-free error and execute arbitrary code on the target system.
Successful exploitation of the vulnerability may allow an attacker to compromise vulnerable system.
4) Permissions, Privileges, and Access Controls (CVE-ID: CVE-2020-13631)
The vulnerability allows a local user to bypass certain security restrictions.
