CVE-2026-26269

Vim is an advanced text editor that seeks to provide the power of the de-facto Unix editor 'Vi', with a more complete feature set. Vim is a highly configurable text editor built to enable efficient text editing. It is an improved version of the vi editor distributed with most UNIX systems.

Security Fix(es):

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)

• CVE-2026-26269: fix stack-based buffer overflow in NetBeans integration that could lead to a crash or arbitrary code execution via a malicious server

• SECURITY UPDATE: stack-based buffer overflow in option callback functions: illegal_char() and did_set_string_option() wrote the E539/E526/E535 option errors into the caller's 80-byte errbuf[] with unbounded sprintf(). The call site reported upstream, did_set_langmap() in src/map.c, does not exist in this version, where 'langmap' errors are reported through EMSG2() into a bounded buffer.
  • debian/patches/CVE-2024-22667.patch: introduce ERR_BUFLEN and use snprintf() bounded by it at the three sprintf() sites, in src/option.c and src/option.h; matches upstream patch 9.0.2142.
  • CVE-2024-22667
• SECURITY UPDATE: buffer overflow in 'helpfile' option handling: get_tagfname() copied the user-controlled 'helpfile' value into a MAXPATHL buffer with STRCPY() and then appended "tags" at the tail, so an over-long 'helpfile' overflowed the buffer.
  • debian/patches/CVE-2026-25749.patch: bound the copy with vim_strncpy() leaving room for the "tags" suffix, in src/tag.c; matches upstream patches 9.1.2132 and 9.1.2133.
  • CVE-2026-25749
• SECURITY UPDATE: buffer overflow in the netbeans specialKeys command: special_keys() walked the modifier prefix writing two bytes per modifier into the 64-byte keybuf[] with no bound, so a long modifier run overflowed it.
  • debian/patches/CVE-2026-26269.patch: stop the modifier loop while i + 2 < KEYBUFLEN, in src/netbeans.c; matches upstream patch 9.1.2148.
  • CVE-2026-26269
• SECURITY UPDATE: command injection via netrw URIs: the hostname and port taken from a netrw URI were interpolated unescaped into the command passed to system(), so shell metacharacters in the host or port ran arbitrary commands.
  • debian/patches/CVE-2026-28417.patch: validate the host against an RFC1123 hostname / IPv4 / IPv6 pattern at the four netrw entry points and shellescape() the host, user and port in s:MakeSshCmd(), in runtime/autoload/netrw.vim; matches upstream patches 9.2.0073, 9.2.0089 and 9.2.0553.
  • CVE-2026-28417
• SECURITY UPDATE: crash and huge allocation recovering a corrupted swap file: ml_recover() trusted pe_page_count, pe_bnum, pe_old_lnum and pe_line_count from the swap file, so bogus values caused a multi-GB mf_get() allocation or a SEGV inside readfile().
  • debian/patches/CVE-2026-28421.patch: bound pe_page_count and pe_bnum against mf_blocknr_max and validate pe_old_lnum and pe_line_count before use, in src/memline.c; matches upstream patch 9.2.0077.
  • CVE-2026-28421
• SECURITY UPDATE: command injection via newline in glob(): the newline character was missing from SHELL_SPECIAL, so it was not escaped before mch_expand_wildcards() handed the pattern to the shell and could act as a command separator.
  • debian/patches/CVE-2026-33412.patch: add '\n' to SHELL_SPECIAL, in src/os_unix.c; matches upstream patch 9.2.0202.
  • CVE-2026-33412
• SECURITY UPDATE: modeline security bypass: several options holding expressions could be set from a modeline, so opening a crafted file evaluated attacker-supplied expressions. In this version the expressions reachable this way are the 'statusline'-style %{} items of 'printheader' and 'guitabtooltip', which were evaluated in the sandbox only; the F{func} flag of 'complete' and the mapset() function named by the upstream advisory arrived in later releases and are not present in this version.
  • debian/patches/patch-8.1.1366-using-expressions-in-a-modeline-is-unsafe.patch: add the 'modelineexpr' option and the P_MLE flag, refuse P_MLE options in a modeline unless 'modelineexpr' is set, mark the expression-bearing options P_MLE, and document 'modelineexpr' and E992, in src/option.c, src/option.h and runtime/doc/options.txt; prerequisite…
