Fixes the following vulnerabilities:
- 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.

- 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.
