Description
This security bulletin contains information about 8 secuirty vulnerabilities.
1) 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.
2) 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.
3) 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.
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) 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.
6) 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.
7) 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.
8) 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.
