Description
This security bulletin contains information about 15 secuirty vulnerabilities.
1) Heap-based buffer overflow (CVE-ID: CVE-2022-2522)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error within the ins_compl_infercase_gettext() function in insexpand.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.
2) Heap-based buffer overflow (CVE-ID: CVE-2022-2580)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error within the eval_string() function in typval.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.
3) Heap-based buffer overflow (CVE-ID: CVE-2022-2598)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to a boundary error within the diff_write_buffer() function in diff.c. A remote attacker can trick the victim to open a specially crafted file, trigger a heap-based buffer overflow and crash the application.
4) Out-of-bounds read (CVE-ID: CVE-2022-2816)
The vulnerability allows a remote attacker to gain access to potentially sensitive information.
The vulnerability exists due to a boundary condition within the check_vim9_unlet() function in vim9cmds.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) Use-after-free (CVE-ID: CVE-2022-2817)
The vulnerability allows a remote attacker to compromise vulnerable system.
The vulnerability exists due to a use-after-free error when processing files in testing.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.
6) Heap-based buffer overflow (CVE-ID: CVE-2022-2819)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error in vim9cmds.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.
7) Use-after-free (CVE-ID: CVE-2022-2862)
The vulnerability allows a remote attacker to compromise vulnerable system.
The vulnerability exists due to a use-after-free error in vim9compile.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.
8) NULL pointer dereference (CVE-ID: CVE-2022-2874)
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 vim9compile.c. A remote attacker can trick the victim top open a specially crafted file and crash the application.
9) Use-after-free (CVE-ID: CVE-2022-2889)
