Description

This security bulletin contains information about 6 secuirty vulnerabilities.


1) Out-of-bounds read (CVE-ID: CVE-2022-1851)

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

The vulnerability exists due to illegal memory access and leads to an out-of-bounds read vulnerability in the gchar_cursor() function. A local attacker can trick the victim into opening a specially crafted file, leading to a system crash or code execution.


2) Use-after-free (CVE-ID: CVE-2022-1898)

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

The vulnerability exists due to Illegal memory access and leads to a use-after-free vulnerability in the find_pattern_in_path() function. A local attacker can trick the victim into opening a specially crafted file, leading to a system crash or code execution.


3) Heap-based buffer overflow (CVE-ID: CVE-2022-1942)

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

The vulnerability exists due to a boundary error in buffer.c. A remote attacker can trick the victim to open a specially crafted file, trigger a 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) Out-of-bounds write (CVE-ID: CVE-2022-1897)

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

The vulnerability exists due to Illegal memory access and leads to an out-of-bounds write vulnerability in the vim_regsub_both() function. A local attacker can trick the victim into opening a specially crafted file, leading to a system crash or code execution.


5) Use-after-free (CVE-ID: CVE-2022-1968)

The vulnerability allows a remote attacker to compromise vulnerable system.

The vulnerability exists due to a use-after-free error in search.c. 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) Stack-based buffer overflow (CVE-ID: CVE-2022-1771)

The vulnerability allows a remote attacker to perform a denial of service attack.

The vulnerability exists due to a boundary error when providing certain input. A remote attacker can trigger stack-based buffer overflow and perform a denial of service attack.
