Fix CVE(s): CVE-2026-73073
Type: advisorySources: OSV
* SECURITY UPDATE: arbitrary Ex command execution during C omni-completion: escaping only "/" and "\\" in the typeref/typename tag field was not enough. With no "/" in the payload an unclosed "[" makes :vimgrep's pattern skipping fail, after which the command parser treats a following "|" as a command separator, so a crafted tags entry still runs arbitrary Ex/OS commands when C omni-completion is invoked on a hostile .c file. - debian/patches/CVE-2026-73073.patch: match the type field literally with \V ... \m around escape(typename, '/\') when building the :vimgrep pattern in s:StructMembers(), in runtime/autoload/ccomplete.vim; matches upstream patch 9.2.0845. - CVE-2026-73073
