Description
This security bulletin contains information about 12 secuirty vulnerabilities.
1) Use of out-of-range pointer offset (CVE-ID: CVE-2022-0554)
The vulnerability allows a remote attacker to crash the application.
The vulnerability exists due to a boundary error when reading files. A remote attacker can trick the victim to open a specially crafted file and crash the application.
2) Heap-based buffer overflow (CVE-ID: CVE-2022-0714)
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 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.
3) Buffer overflow (CVE-ID: CVE-2022-0729)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error when processing files. A remote attacker can create a specially crafted file, 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) 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.
5) 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.
6) 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.
7) 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.
8) 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.
9) 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.
10) 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.
11) 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.
12) 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.
