Description
This security bulletin contains information about 13 secuirty vulnerabilities.
1) 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.
2) 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.
3) 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.
4) 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.
5) 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.
6) Stack-based buffer overflow (CVE-ID: CVE-2022-3324)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
