Description

This security bulletin contains information about 6 secuirty vulnerabilities.


1) Heap-based buffer overflow (CVE-ID: CVE-2022-0572)

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

The vulnerability exists due to a boundary error when repeatedly using :retab. A remote attacker can trick the victim to open a specially crafted file, 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.


2) Stack-based buffer overflow (CVE-ID: CVE-2022-0408)

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

The vulnerability exists due to a boundary error when looking for spell suggestions. A remote unauthenticated attacker can trick the victim to open a specially crafted file, trigger a stack-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) Use-after-free (CVE-ID: CVE-2022-0413)

The vulnerability allows a remote attacker to compromise vulnerable system.

The vulnerability exists due to a use-after-free error when using freed memory when substitute with function call . A remote attacker can trick the victim to open a specially crafted file, 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.


4) Out-of-bounds read (CVE-ID: CVE-2022-0393)

The vulnerability allows a remote attacker to crash the application.

The vulnerability exists due to a boundary condition when recording and using Select mode . A remote attacker can create a specially crafted file, trick the victim into opening it, trigger out-of-bounds read error and crash the application.


5) Heap-based buffer overflow (CVE-ID: CVE-2022-0417)

The vulnerability allows a remote attacker to crash the application.

The vulnerability exists due to a boundary error. A remote attacker can trick the victim to open a specially crafted file and crash the application.


6) Use-after-free (CVE-ID: CVE-2022-0443)

The vulnerability allows a remote attacker to compromise vulnerable system.

The vulnerability exists due to a use-after-free error when using freed memory with :lopen and :bwipe . A remote attacker can trick the victim to open a specially crafted file, 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.
