EulerOS Virtualization 2.13.0 : vim (EulerOS-SA-2026-2193)

high Nessus Plugin ID 319336

Synopsis

The remote EulerOS Virtualization host is missing multiple security updates.

Description

According to the versions of the vim packages installed, the EulerOS Virtualization installation on the remote host is affected by the following vulnerabilities :

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-2026-26269)

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.(CVE-2026-25749)

Tenable has extracted the preceding description block directly from the EulerOS Virtualization vim security advisory.

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

Solution

Update the affected vim packages.
