Description
This security bulletin contains information about 12 secuirty vulnerabilities.
1) Division by zero (CVE-ID: CVE-2023-3896)
The vulnerability allows a remote attacker to crash the application.
The vulnerability exists due to division by zero error within the scroll_cursor_bot() function. A remote attacker can trick the victim to open a specially crafted file and crash the application.
2) Use-after-free (CVE-ID: CVE-2023-4733)
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.
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) 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.
6) 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.
7) Heap-based buffer overflow (CVE-ID: CVE-2023-4751)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error within the utfc_ptr2len() function in mbyte.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.
