Vim is an open source, command line text editor. Prior to version 9.2.0450, a heap buffer overflow exists in read_compound() in src/spellfile.c when loading a crafted spell file (.spl) with UTF-8 encoding active. An attacker-controlled length field in the spell file's compound section overflows a 32-bit signed integer multiplication, causing a small buffer to be allocated for a write loop that runs many iterations, overflowing the heap. Because the 'spelllang' option can be set from a modeline, a text file modeline can trigger spell file loading if a malicious .spl file has been planted on the runtimepath. This issue has been patched in version 9.2.0450.

The remote openSUSE 16 host has packages installed that are affected by multiple vulnerabilities as referenced in the openSUSE-SU-2026:20828-1 advisory.

    This update for vim fixes the following issues

    - CVE-2026-39881: command injection in NetBeans interface can lead to arbitrary file reads and writes     (bsc#1261833).

    - CVE-2026-45130: Prior to version 9.2.0450, a heap buffer overflow exists in read_compound() in     src/spellfile.c when       loading a crafted spell file (.spl) with UTF-8 encoding active (bsc#1264708).
    - CVE-2026-46483: command injection via ` tar#Vimuntar()` in `runtime/autoload/tar.vim` when decompressing     `.tgz`       archives on Unix-like systems (bsc#1265360).

The remote Ubuntu 14.04 LTS / 16.04 LTS / 18.04 LTS / 20.04 LTS / 22.04 LTS / 24.04 LTS / 25.10 / 26.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-8304-1 advisory.

    Joshua Rogers discovered that Vim incorrectly handled certain URL schemes in the netrw plugin. An attacker     could possibly use this issue to execute arbitrary commands. (CVE-2026-42307)

    It was discovered that Vim incorrectly handled command-line completion for the :find command. An attacker     could possibly use this issue to execute arbitrary commands. (CVE-2026-44656)

    Daniel Cervera discovered that Vim incorrectly handled loading spell files. An attacker could possibly use     this issue to cause a denial of service, or to execute arbitrary code. (CVE-2026-45130)

The version of Vim installed on the remote host is prior to 9.2.0450. It is, therefore, affected by a vulnerability as referenced in the GHSA-q4jv-r9gj-6cwv advisory.

  - An integer overflow in the `read_compound()` function within `src/spellfile.c` produces a heap buffer     overflow when processing malicious spell files (`.spl`) with UTF-8 encoding enabled. The     attacker-controlled `sectionlen` field of an `SN_COMPOUND` section triggers a 32-bit signed integer     wraparound during buffer size calculation, allocating a 27-byte buffer that receives approximately     1 billion bytes. Activation occurs through modeline settings in unrelated text files. (CVE-2026-45130)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.
