Description
This security bulletin contains information about 8 secuirty vulnerabilities.
1) Use-after-free (CVE-ID: CVE-2022-3256)
The vulnerability allows a remote attacker to compromise vulnerable system.
The vulnerability exists due to a use-after-free error within the movemark() function in mark.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.
2) Stack-based buffer overflow (CVE-ID: CVE-2022-3324)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error when handling files within the win_redr_ruler(0 function in drawscreen.c. A remote attacker can trick the victim to open a specially crafted file, trigger a stack-based buffer overflow and execute arbitrary code on the target system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
3) Use-after-free (CVE-ID: CVE-2022-3352)
The vulnerability allows a remote attacker to compromise vulnerable system.
The
vulnerability exists due to a use-after-free error when handling files
within the did_set_string_option() function in optionstr.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.
4) Use-after-free (CVE-ID: CVE-2022-3235)
The vulnerability allows a remote attacker to compromise vulnerable system.
The vulnerability exists due to a use-after-free error within the getcmdline_int() function in ex_getln.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.
5) Heap-based buffer overflow (CVE-ID: CVE-2022-3234)
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 at mbyte.c. A remote attacker can trick the victim to open a specially crafted fule, 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.
6) Buffer overflow (CVE-ID: CVE-2022-3296)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error when processing files within the ex_finally() function in ex_eval.c. 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.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
7) Use-after-free (CVE-ID: CVE-2022-3297)
The vulnerability allows a remote attacker to compromise vulnerable system.
The vulnerability exists due to a use-after-free error within the process_next_cpt_value() function in insexpand.c when processing files. A remote attacker can trick the victim to open a specially crafted flie, 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.
8) NULL pointer dereference (CVE-ID: CVE-2022-3278)
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 eval.c. A remote attacker can perform a denial of service (DoS) attack.
