Security Bulletin
Summary
IBM Cloud Pak for Data System 1.0 includes Vim, which is affected by multiple security vulnerabilities. These vulnerabilities include command injection (CVE-2026-28417), multiple heap-based buffer overflows (CVE-2026-28418, CVE-2026-28420, CVE-2026-28421), heap-based buffer underflow (CVE-2026-28419), and stack-buffer-overflow (CVE-2026-28422). CVE-2026-28420 also involves out-of-bounds read issues. These vulnerabilities could allow attackers to execute arbitrary code, cause memory corruption, or trigger denial of service conditions. Exploitation of these vulnerabilities could lead to unauthorized access to system resources, data compromise, or service disruption.
Vulnerability Details
CVEID: CVE-2026-28417
DESCRIPTION: Vim is an open source, command line text editor. Prior to version 9.2.0073, an OS command injection vulnerability exists in the `netrw` standard plugin bundled with Vim. By inducing a user to open a crafted URL (e.g., using the `scp://` protocol handler), an attacker can execute arbitrary shell commands with the privileges of the Vim process. Version 9.2.0073 fixes the issue.
CWE: CWE-86: Improper Neutralization of Invalid Characters in Identifiers in Web Pages
CVSS Source: NVD
CVSS Base score: 7.8
CVSS Vector: (CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H)
CVEID: CVE-2026-28418
DESCRIPTION: Vim is an open source, command line text editor. Prior to version 9.2.0074, a heap-based buffer overflow out-of-bounds read exists in Vim's Emacs-style tags file parsing logic. When processing a malformed tags file, Vim can be tricked into reading up to 7 bytes beyond the allocated memory boundary. Version 9.2.0074 fixes the issue.
CWE: CWE-122: Heap-based Buffer Overflow
CVSS Source: NVD
CVSS Base score: 5.5
CVSS Vector: (CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:H)
CVEID: CVE-2026-28419
DESCRIPTION: Vim is an open source, command line text editor. Prior to version 9.2.0075, a heap-based buffer underflow exists in Vim's Emacs-style tags file parsing logic. When processing a malformed tags file where a delimiter appears at the start of a line, Vim attempts to read memory immediately preceding the allocated buffer. Version 9.2.0075 fixes the issue.
CWE: CWE-124: Buffer Underwrite ('Buffer Underflow')
CVSS Source: NVD
CVSS Base score: 6.6
CVSS Vector: (CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:L/I:L/A:H)
CVEID: CVE-2026-28420
DESCRIPTION: Vim is an open source, command line text editor. Prior to version 9.2.0076, a heap-based buffer overflow WRITE and an out-of-bounds READ exist in Vim's terminal emulator when processing maximum combining characters from Unicode supplementary planes. Version 9.2.0076 fixes the issue.
CWE: CWE-122: Heap-based Buffer Overflow
CVSS Source: NVD
CVSS Base score: 4.4
CVSS Vector: (CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:N/I:L/A:L)
CVEID: CVE-2026-28421
DESCRIPTION: Vim is an open source, command line text editor. Versions prior to 9.2.0077 have a heap-buffer-overflow and a segmentation fault (SEGV) exist in Vim's swap file recovery logic. Both are caused by unvalidated fields read from crafted pointer blocks within a swap file. Version 9.2.0077 fixes the issue.
CWE: CWE-20: Improper Input Validation
CVSS Source: NVD
CVSS Base score: 7.8
CVSS Vector: (CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H)
CVEID: CVE-2026-28422
DESCRIPTION: Vim is an open source, command line text editor. Prior to version 9.2.0078, a stack-buffer-overflow occurs in `build_stl_str_hl()` when rendering a statusline with a multi-byte fill character on a very wide terminal. Version 9.2.0078 patches the issue.
CWE: CWE-121: Stack-based Buffer Overflow
CVSS Source: security-advisories@github.com
CVSS Base score: 2.2
CVSS Vector: (CVSS:3.1/AV:L/AC:H/PR:L/UI:R/S:U/C:N/I:L/A:N)

Disclaimer
According to the Forum of Incident Response and Security Teams (FIRST), the Common Vulnerability Scoring System (CVSS) is an "industry open standard designed to convey vulnerability severity and help to determine urgency and priority of response." IBM PROVIDES THE CVSS SCORES ""AS IS"" WITHOUT WARRANTY OF ANY KIND, INCLUDING THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. CUSTOMERS ARE RESPONSIBLE FOR ASSESSING THE IMPACT OF ANY ACTUAL OR POTENTIAL SECURITY VULNERABILITY. In addition to other efforts to address potential vulnerabilities, IBM periodically updates the record of components contained in our product offerings. As part of that effort, if IBM identifies previously unidentified packages in a product/service inventory, we address relevant vulnerabilities regardless of CVE date. Inclusion of an older CVEID does not demonstrate that the referenced product has been used by IBM since that date, nor that IBM was aware of a vulnerability as of that date. We are making clients aware of relevant vulnerabilities as we become aware of them. "Affected Products and Versions" referenced in IBM Security Bulletins are intended to be only products and versions that are supported by IBM and have not passed their end-of-support or warranty date. Thus, failure to reference unsupported or extended-support products and versions in this Security Bulletin does not constitute a determination by IBM that they are unaffected by the vulnerability. Reference to one or more unsupported versions in this Security Bulletin shall not create an obligation for IBM to provide fixes for any unsupported or extended-support products or versions.
