Description

This security bulletin contains information about 11 secuirty vulnerabilities.


1) Use-after-free (CVE-ID: CVE-2023-4733)

The vulnerability allows a remote attacker to crash the application.

The vulnerability exists due to a use-after-free error within the do_ecmd() function in ex_cmds.c. A remote attacker can trick the victim to open a specially crafted file and crash the application.



2) Use-after-free (CVE-ID: CVE-2023-4750)

The vulnerability allows a remote attacker to crash the application.

The vulnerability exists due to a use-after-free error within the is_qf_win() function in quickfix.c. A remote attacker can trick the victim to open a specially crafted file and crash the application.


3) Integer overflow (CVE-ID: CVE-2023-4734)

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

The vulnerability exists due to integer overflow within the f_fullcommand() function in ex_docmd.c. A remote attacker can trick the victim to open a specially crafted file, trigger integer 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 read (CVE-ID: CVE-2023-4735)

The vulnerability allows a remote attacker to gain access to potentially sensitive information.

The vulnerability exists due to a boundary condition within the do_addsub() function in ops.c. A remote attacker can create a specially crafted file, trick the victim into opening it, trigger an out-of-bounds read error and read contents of memory on the system.


5) Untrusted search path (CVE-ID: CVE-2023-4736)

The vulnerability allows a remote attacker to compromise the affected system.

The vulnerability exists due to usage of an untrusted search path when searching for perl, zig, ruby filetype plugins as well as zip and gzip autoload plugins. A remote attacker can trick the victim into downloading specially crafted files and opening one of the downloaded files using the affected software.

Successful exploitation of the vulnerability may lead to remote code execution.


6) Buffer overflow (CVE-ID: CVE-2023-4738)

The vulnerability allows a remote attacker to crash the application.

The vulnerability exists due to a boundary error within the vim_regsub_both() function in src/regexp.c. A remote attacker can create a specially crafted file, trick the victim into opening it, trigger memory corruption and crash the application.


7) Use-after-free (CVE-ID: CVE-2023-4752)

The vulnerability allows a remote attacker to crash the application.

The vulnerability exists due to a use-after-free error within the ins_compl_get_exp() function in insexpand.c. A remote attacker can trick the victim to open a specially crafted file and crash the application.



8) Heap-based buffer overflow (CVE-ID: CVE-2023-4781)

The vulnerability allows a remote attacker to crash the application.

The vulnerability exists due to a boundary error within the vim_regsub_both() function. A remote attacker can trick the victim to open a specially crafted file, trigger a heap-based buffer overflow and crash the application.


9) Heap-based buffer overflow (CVE-ID: CVE-2023-5344)

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

The vulnerability exists due to a boundary error within the trunc_string() function in message.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.


10) NULL pointer dereference (CVE-ID: CVE-2023-5441)

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 src/gui.c. A remote attacker can trick the victim to open a specially crafted file and crash the application.


11) Use-after-free (CVE-ID: CVE-2023-5535)

The vulnerability allows a remote attacker to compromise vulnerable system.

The vulnerability exists due to a use-after-free error within the editing_arg_idx() function. 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.
