Description
This security bulletin contains information about 15 secuirty vulnerabilities.
1) NULL pointer dereference (CVE-ID: CVE-2022-1725)
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 (DoS) attack.
2) 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.
3) Heap-based buffer overflow (CVE-ID: CVE-2022-1886)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error in register.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) Out-of-bounds write (CVE-ID: CVE-2022-2000)
The vulnerability allows a remote attacker to compromise vulnerable system.
The vulnerability exists due to a boundary error when processing untrusted input in ex_docmd.c. 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-2022-2042)
The vulnerability allows a remote attacker to compromise vulnerable system.
The vulnerability exists due to a use-after-free error in spell.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.
7) Integer overflow (CVE-ID: CVE-2023-46246)
The vulnerability allows a remote attacker to crash the application.
The vulnerability exists due to integer overflow. A remote attacker can trick the victim to open a specially crafted file and perform a denial of service (DoS) attack.
8) Use-after-free (CVE-ID: CVE-2023-48231)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to a use-after-free error when closing the window. A remote attacker can trick the victim to open a specially crafted file and crash the application.
9) Integer overflow (CVE-ID: CVE-2023-48232)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to integer overflow when calculating the line offset for overlong lines and smooth scrolling is enabled and the cpo-settings include the 'n' flag. A remote attacker can trick the victim to open a specially crafted file, trigger an integer overflow and crash the application.10) Integer overflow (CVE-ID: CVE-2023-48233)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to integer overflow if the count after the :s command is larger than what fits into a (signed) long variable. A remote attacker can trick the victim to open a specially crafted file, trigger an integer overflow and crash the application.11) Integer overflow (CVE-ID: CVE-2023-48234)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to integer overflow when using the z= command. A remote attacker can trick the victim to open a specially crafted file, trigger an integer overflow and crash the application.12) Integer overflow (CVE-ID: CVE-2023-48235)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to integer overflow when parsing relative ex addresses. A remote attacker can trick the victim to open a specially crafted file, trigger an integer overflow and crash the application.13) Integer overflow (CVE-ID: CVE-2023-48236)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to integer overflow when using the z= command. A remote attacker can trick the victim to open a specially crafted file, trigger an integer overflow and crash the application.
14) Integer overflow (CVE-ID: CVE-2023-48237)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to integer overflow when shifting lines in operator pending mode. A remote attacker can trick the victim to open a specially crafted file, trigger an integer overflow and crash the application.
15) Use-after-free (CVE-ID: CVE-2023-48706)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to a use-after-free error within the ex_substitute() function in src/charset.c when executing the ":s" command. A remote attacker can trick the victim to open a specially crafted file, trigger a use-after-free error and crash the application.
