Description
This security bulletin contains information about 9 secuirty vulnerabilities.
1) NULL pointer dereference (CVE-ID: CVE-2022-0696)
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 Vim when switching tabpage while in the cmdline window. A remote attacker can perform a denial of service (DoS) attack.
2) Stack-based buffer overflow (CVE-ID: CVE-2022-0629)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error when using many composing characters in error message. 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) 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.
4) 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.
5) 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.
6) 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.
7) 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.
8) 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.
9) Use of out-of-range pointer offset (CVE-ID: CVE-2022-0685)
The vulnerability allows a remote attacker to crash the application.
The vulnerability exists due to improper input validation when processing special multi-byte characters. A remote attacker can trick the victim to open a specially crafted file and crash the application.
