Description
This security bulletin contains information about 11 secuirty vulnerabilities.
1) Out-of-bounds read (CVE-ID: CVE-2022-1720)
The vulnerability allows a remote attacker to gain access to potentially sensitive information.
The vulnerability exists due to a boundary condition in normal.c. A remote attacker can create a specially crafted file, trick the victim into opening it, trigger out-of-bounds read error and read contents of memory on the system.
2) NULL pointer dereference (CVE-ID: CVE-2022-2208)
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 diff.c. A remote attacker can perform a denial of service (DoS) attack.
3) Heap-based buffer overflow (CVE-ID: CVE-2022-2207)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error in edit.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.
4) Out-of-bounds read (CVE-ID: CVE-2022-2183)
The vulnerability allows a remote attacker to gain access to potentially sensitive information.
The vulnerability exists due to a boundary condition in indent.c. A remote attacker can create a specially crafted file, trick the victim into opening it, trigger out-of-bounds read error and read contents of memory on the system.
5) Heap-based buffer overflow (CVE-ID: CVE-2022-2284)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error in utfc_ptr2len() function at mbyte.c:2113. A remote attacker can trick the victim into opening a specially crafted file, trigger a heap-based buffer overflow and execute arbitrary code on the target system.
6) Integer overflow (CVE-ID: CVE-2022-2285)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to integer overflow in del_typebuf() function at getchar.c:1204. A remote attacker can pass specially crafted data to the application, trigger integer overflow and execute arbitrary code on the target system.
7) Stack-based buffer overflow (CVE-ID: CVE-2022-2304)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error in spell_dump_compl() function at spell.c:4038. A remote unauthenticated attacker can trick the victim into opening a specially crafted file to trigger stack-based buffer overflow and execute arbitrary code on the target system.
8) Use-after-free (CVE-ID: CVE-2022-2345)
The vulnerability allows a remote attacker to compromise vulnerable system.
The vulnerability exists due to a use-after-free error in function skipwhite at charset.c:1428. A remote attacker can trick the victim to open a specially crafted file and compromise vulnerable system.
9) Heap-based buffer overflow (CVE-ID: CVE-2022-2344)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error in ins_compl_add() function at insexpand.c:751. A remote attacker can trick the victim into opening a specially crafted data, 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) Use-after-free (CVE-ID: CVE-2022-2042)
The vulnerability allows a remote attacker to compromise vulnerable system.
The vulnerability exists due to a use-after-free error in spell.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.
11) Out-of-bounds write (CVE-ID: CVE-2022-2000)
The vulnerability allows a remote attacker to compromise vulnerable system.
The vulnerability exists due to a boundary error when processing untrusted input in ex_docmd.c. A remote attacker can create a specially crafted file, trick the victim into opening it using the affected software, trigger out-of-bounds write and execute arbitrary code on the target system.
