Description

This security bulletin contains information about 5 vulnerabilities.


1) Division by zero (CVE-ID: CVE-2019-16168)

CWE-ID: CWE-369 - Divide By Zero

CVSSv4: 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


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)

CWE-ID: CWE-190 - Integer overflow

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Green


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)

CWE-ID: CWE-416 - Use After Free

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Amber


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)

CWE-ID: CWE-264 - Permissions, Privileges, and Access Controls

CVSSv4: CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:N/VI:L/VA:N/SC:N/SI:N/SA:N/E:U/U:Clear


The vulnerability allows a local user to bypass certain security restrictions.

The vulnerability exists due an error in alter.c and build.c files in SQLite that allows a local user to rename a virtual table into a shadow table. A local user with permissions to create virtual tables can renamed them and gain unauthorized access to the fronted application.


5) NULL pointer dereference (CVE-ID: CVE-2020-13632)

CWE-ID: CWE-476 - NULL Pointer Dereference

CVSSv4: CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear


The vulnerability allows a local user to perform a denial of service (DoS) attack.

The vulnerability exists due to a NULL pointer dereference error in ext/fts3/fts3_snippet.c in SQLite. A local user can trigger denial of service conditions via a crafted matchinfo() query.
