Description

This security bulletin contains information about 8 secuirty vulnerabilities.

1) Use-after-free (CVE-ID: CVE-2020-15389.)

The vulnerability allows a remote attacker to compromise vulnerable system.

The vulnerability exists due to a use-after-free error when processing image files. A remote attacker can pass specially crafted image to the application, trigger a use-after-free error and execute arbitrary code.

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

2) Heap-based buffer overflow (CVE-ID: CVE-2020-27814)

The vulnerability allows a remote attacker to execute arbitrary code on the target system.

The vulnerability exists due to a boundary error in lib/openjp2/mqc.c. A remote attacker can pass specially crafted image to the application, trigger heap-based buffer overflow and execute arbitrary code on the target system.

Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.

3) Buffer overflow (CVE-ID: CVE-2020-27824)

The vulnerability allows a remote attacker to execute arbitrary code on the target system.

The vulnerability exists due to a boundary error when processing graphic files in lib/openjp2/dwt.c. A remote attacker can create a specially crafted image, trick the victim into opening it, trigger memory corruption and execute arbitrary code on the target system.

Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.

4) Heap-based buffer overflow (CVE-ID: CVE-2020-27841)

The vulnerability allows a remote attacker to execute arbitrary code on the target system.

The vulnerability exists due to a boundary error. A remote attacker can pass specially crafted image to the application, trigger heap-based buffer overflow and execute arbitrary code on the target system.

Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.

5) Heap-based buffer overflow (CVE-ID: CVE-2020-27844)

The vulnerability allows a remote attacker to execute arbitrary code on the target system.

The vulnerability exists due to a boundary error in lib/openjp2/t2.c. A remote attacker can pass specially crafted image to the application, trigger heap-based buffer overflow and execute arbitrary code on the target system.

Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.

6) Heap-based buffer overflow (CVE-ID: CVE-2020-27845)

The vulnerability allows a remote attacker to execute arbitrary code on the target system.

The vulnerability exists due to a boundary error in lib/openjp2/pi.c. A remote attacker can pass specially crafted image, trigger heap-based buffer overflow and execute arbitrary code on the target system.

Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.

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

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.

8) Out-of-bounds read (CVE-ID: CVE-2020-27843)

The vulnerability allows a remote attacker to gain access to potentially sensitive information.

The vulnerability exists due to a boundary condition. A remote attacker can create a specially crafted image, trick the victim into opening it, trigger out-of-bounds read error and read contents of memory on the system.
