{"id":"CLSA-2026-1786093276","summary":"Fix CVE(s): CVE-2026-25749, CVE-2026-34982, CVE-2026-41411","details":"   * SECURITY UPDATE: Heap buffer overflow in get_tagfname() in src/tag.c: the user-settable 'helpfile' option value is copied into a fixed MAXPATHL+1-sized heap buffer with an unbounded STRCPY() when help-file tags are resolved, so a 'helpfile' path longer than MAXPATHL writes past the end of the buffer\n     - debian/patches/CVE-2026-25749.patch: replace the unbounded STRCPY(buf, p_hf) in get_tagfname() with a bounded vim_strncpy() that also leaves room for the \"tags\" tail appended by the following STRCPY(gettail(buf), \"tags\"), so the 'helpfile' value can no longer be copied past the end of the caller's MAXPATHL-sized buffer\n     - CVE-2026-25749\n   * SECURITY UPDATE: Modeline sandbox bypass allowing arbitrary OS command execution when a crafted file is opened: the 'complete', 'guitabtooltip' and 'printheader' options are missing the P_MLE flag, so a modeline can set them to expressions that are evaluated outside the 'modelineexpr' guard\n     - debian/patches/CVE-2026-34982.patch: add the P_MLE flag to the 'complete', 'guitabtooltip' and 'printheader' entries of the option table in src/option.c so a modeline can no longer set them while 'modelineexpr' is off; the upstream mapset() hunk is dropped as mapset() does not exist in 8.1.0875\n     - CVE-2026-34982\n   * SECURITY UPDATE: Command injection during tag resolution in expand_tag_fname() in src/tag.c: the filename field read from a tags file is passed to ExpandOne() for wildcard and environment-variable expansion, so a crafted tags file containing backtick syntax makes vim execute the embedded command through the shell with the user's privileges\n     - debian/patches/CVE-2026-41411.patch: guard the wildcard expansion in expand_tag_fname() with vim_strchr(fname, '`') == NULL so a tags-file filename field containing backticks is never handed to ExpandOne() and can no longer reach the shell\n     -
