Description

This security bulletin contains information about 4 vulnerabilities.


1) Use-after-free (CVE-ID: CVE-2021-20227)

CWE-ID: CWE-416 - Use After Free

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


The vulnerability allows an attacker to compromise vulnerable system.

The vulnerability exists due to a use-after-free error when processing SELECT queries in "src/select.c" if a subquery with both a correlated WHERE clause and a "HAVING 0" clause is used and the parent query is an aggregate. A remote attacker can execute a specially crafted query to trigger a use-after-free error and execute arbitrary code on the system.

Successful exploitation of the vulnerability may allow an attacker to compromise vulnerable system.


2) NULL pointer dereference (CVE-ID: CVE-2020-27842)

CWE-ID: CWE-476 - NULL Pointer Dereference

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/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 a NULL pointer dereference error in openjpeg's t2 encoder in versions prior to 2.4.0. A remote attacker can pass specially crafted image to the application and perform a denial of service (DoS) attack.


3) Improper input validation (CVE-ID: CVE-2021-2240)

CWE-ID: CWE-20 - Improper input validation

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


The vulnerability allows a remote non-authenticated attacker to read and manipulate data.
