Description
This security bulletin contains information about 16 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-2022-2264)
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.
3) Heap-based buffer overflow (CVE-ID: CVE-2022-2284)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.

4) 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.
5) 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.
6) 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.
