Description
This security bulletin contains information about 10 secuirty vulnerabilities.
1) Use of out-of-range pointer offset (CVE-ID: CVE-2022-0554)
The vulnerability allows a remote attacker to crash the application.
The vulnerability exists due to a boundary error when reading files. A remote attacker can trick the victim to open a specially crafted file and crash the application.
2) Heap-based buffer overflow (CVE-ID: CVE-2022-0572)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error when repeatedly using :retab. A remote attacker can trick the victim to open a specially crafted file, trigger 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.
3) Use of out-of-range pointer offset (CVE-ID: CVE-2022-0685)
The vulnerability allows a remote attacker to crash the application.
The vulnerability exists due to improper input validation when processing special multi-byte characters. A remote attacker can trick the victim to open a specially crafted file and crash the application.
4) Heap-based buffer overflow (CVE-ID: CVE-2022-0714)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error. A remote attacker can trick the victim to open a specially crafted file, trigger 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.
5) Buffer overflow (CVE-ID: CVE-2022-0729)
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. 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.
6) Heap-based buffer overflow (CVE-ID: CVE-2022-0943)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error. 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.
7) Heap-based buffer overflow (CVE-ID: CVE-2022-1616)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error. 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.
8) Heap-based buffer overflow (CVE-ID: CVE-2022-1619)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error when processing data in the cmdline_erase_chars() function in ex_getln.c. A remote attacker can trick the victim to open a specially crafted file, trigger 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.
9) NULL pointer dereference (CVE-ID: CVE-2022-1620)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to a NULL pointer dereference error within the vim_regexec_string() function in regexp.c. A remote attacker can trick the victim to open a specially crafted file, trigger NULL pointer dereference error and crash the application.
10) Heap-based buffer overflow (CVE-ID: CVE-2022-1621)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error. 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.
