Security Bulletin: IBM App Connect Enterprise Certified Container operands may be vulnerable to arbitrary code execution due to CVE-2022-2124, CVE-2022-2125, CVE-2022-2126 and CVE-2022-2129

Summary

Vim is not used directly by IBM App Connect Enterprise Certified Container but is present in the operand images as part of the base operating system. Use of vim within IBM App Connect Enterprise Certified Container operands may be vulnerable to arbitrary code execution. This bulletin provides patch information to address the reported vulnerability CVE-2022-2124, CVE-2022-2125, CVE-2022-2126 and CVE-2022-2129 in vim.

Vulnerability Details

CVEID:CVE-2022-2125
**DESCRIPTION:**Vim is vulnerable to a heap-based buffer overflow, caused by improper bounds checking by the get_lisp_indent function in indent.c:1994. By persuading a victim to open a specially-crafted file, a remote attacker could overflow a buffer and execute arbitrary code on the system or cause a denial of service.
CVSS Base score: 7.8
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/229306 for the current score.
CVSS Vector: (CVSS:3.0/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H)

CVEID:CVE-2022-2124
**DESCRIPTION:**Vim could allow a remote attacker to execute arbitrary code on the system, caused by a buffer over-read in the current_quote function in textobject.c:1801. By persuading a victim to open a specially-crafted file, an attacker could exploit this vulnerability to execute arbitrary code on the system or cause a denial of service.
CVSS Base score: 7.8
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/229307 for the current score.
CVSS Vector: (CVSS:3.0/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H)

CVEID:CVE-2022-2126
**DESCRIPTION:**Vim could allow a remote attacker to execute arbitrary code on the system, caused by an out-of-bounds read in the suggest_trie_walk function in spellsuggest.c:1437. By persuading a victim to open a specially-crafted file, an attacker could exploit this vulnerability to execute arbitrary code on the system or cause a denial of service.
CVSS Base score: 7.8
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/229305 for the current score.
CVSS Vector: (CVSS:3.0/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H)

CVEID:CVE-2022-2129
**DESCRIPTION:**Vim could allow a remote attacker to execute arbitrary code on the system, caused by an out-of-bounds write in the vim_regsub_both function in regexp.c:1973. By persuading a victim to open a specially-crafted file, an attacker could exploit this vulnerability to execute arbitrary code on the system or cause a denial of service.
