Description
This security bulletin contains information about 7 secuirty vulnerabilities.
1) Out-of-bounds write (CVE-ID: CVE-2022-2210)
The vulnerability allows a remote attacker to compromise vulnerable system.
The vulnerability exists due to a boundary error when processing untrusted input in diff.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.
2) 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.
3) 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.
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) 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.
7) Heap-based buffer overflow (CVE-ID: CVE-2022-2343)
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.
