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.

The version of Tencent Linux installed on the remote TencentOS Server 4 host is prior to tested version. It is, therefore, affected by multiple vulnerabilities as referenced in the TSSA-2026:0178 advisory.

    Package updates are available for TencentOS Server 4 that fix the following vulnerabilities:

    CVE-2026-28422:
    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.

    CVE-2026-28421:
    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.

    CVE-2026-28420:
    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.

    CVE-2026-28419:
    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.

    CVE-2026-28418:
    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.

    CVE-2026-28417:
    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.

    CVE-2026-26269:
    Vim is an open source, command line text editor. Prior to 9.1.2148, a stack buffer overflow vulnerability     exists in Vim's NetBeans integration when processing the specialKeys command, affecting Vim builds that     enable and use the NetBeans feature. The Stack buffer overflow exists in special_keys() (in     src/netbeans.c). The while (*tok) loop writes two bytes per iteration into a 64-byte stack buffer (keybuf)     with no bounds check. A malicious NetBeans server can overflow keybuf with a single specialKeys command.
    The issue has been fixed as of Vim patch v9.1.2148.

    CVE-2026-25749:
    Vim is an open source, command line text editor. Prior to version 9.1.2132, a heap buffer overflow     vulnerability exists in Vim's tag file resolution logic when processing the 'helpfile' option. The     vulnerability is located in the get_tagfname() function in src/tag.c. When processing help file tags, Vim     copies the user-controlled 'helpfile' option value into a fixed-size heap buffer of MAXPATHL + 1 bytes     (typically 4097 bytes) using an unsafe STRCPY() operation without any bounds checking. This issue has been     patched in version 9.1.2132.
