Description

This security bulletin contains information about 7 secuirty vulnerabilities.


1) Heap-based buffer overflow (CVE-ID: CVE-2022-1733)

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

The vulnerability exists due to a boundary error in skip_string() function. 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.


2) NULL pointer dereference (CVE-ID: CVE-2022-1674)

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

The vulnerability exists due to a NULL pointer dereference error. A remote attacker can trick the victim to open a specially crafted file and perform a denial of service attack.


3) Out-of-bounds read (CVE-ID: CVE-2022-1629)

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

The vulnerability exists due to a boundary condition in find_next_quote() function. A remote attacker can create a specially crafted file, trick the victim into opening it, trigger out-of-bounds read error, perform a denial of service attack, modify memory, and execute arbitrary code.


4) Buffer overflow (CVE-ID: CVE-2022-1735)

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

The vulnerability exists due to a boundary error in utfc_ptr2len() function. 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.


5) 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.


6) Out-of-bounds write (CVE-ID: CVE-2022-1785)

The vulnerability allows a remote attacker to execute arbitrary code

The vulnerability exists due to a boundary error when processing untrusted input in vim_regsub_both() function. A remote attacker can create a specially crafted file, trick the victim into opening it using the affected software, trigger out-of-bounds write and execute arbitrary code on the target system.


7) Use-after-free (CVE-ID: CVE-2022-1796)

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

The vulnerability exists due to a use-after-free error. 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 target system.

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