Description

This security bulletin contains information about 12 secuirty vulnerabilities.


1) Out-of-bounds read (CVE-ID: CVE-2022-2257)

The vulnerability allows a remote attacker to gain access to potentially sensitive information.

The vulnerability exists due to a boundary condition in msg_outtrans_special() function at message.c:1716. 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) 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.


3) 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.


4) Out-of-bounds read (CVE-ID: CVE-2022-2286)

The vulnerability allows a remote attacker to gain access to potentially sensitive information.

The vulnerability exists due to a boundary condition in ins_bytes() function at change.c:968. 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) Out-of-bounds read (CVE-ID: CVE-2022-2287)

The vulnerability allows a remote attacker to gain access to potentially sensitive information.

The vulnerability exists due to a boundary condition in suggest_trie_walk() function abusing array byts in line spellsuggest.c:1925. 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.


6) Out-of-bounds write (CVE-ID: CVE-2022-2288)

The vulnerability allows a remote attacker to execute arbitrary code on the system.

The vulnerability exists due to a boundary error in parse_command_modifiers() function at ex_docmd.c:3123. 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.


7) Use-after-free (CVE-ID: CVE-2022-2289)

The vulnerability allows a remote attacker to compromise vulnerable system.

The vulnerability exists due to a use-after-free error in ex_diffgetput() function at diff.c:2790. A remote attacker can trick the victim into opening a specially crafted file and compromise vulnerable system.


8) Heap-based buffer overflow (CVE-ID: CVE-2022-2264)

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 into opening a specially crafted data, trigger a heap-based buffer overflow and execute arbitrary code on the target system.


9) 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.


10) 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.


11) 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.


12) Heap-based buffer overflow (CVE-ID: CVE-2022-2343)
