+Subject: [PATCH] patch 9.2.0845: [security]: arbitrary Ex command execution
+ during C omni-completion
+
+Problem:  [security]: arbitrary Ex command execution during C
+          omni-completion (Threonine)
+Solution: Match tags typeref literally to block Ex command injection
+          (Yasuhiro Matsumoto).
+
+Escaping only "/" and "\" left the typeref able to break out of the
+:vimgrep pattern without a "/": an unclosed "[" makes vimgrep's pattern
+skipping fail, and the parser then treats a following "|" as a command
+separator, so the tag value runs as Ex commands during C omni-completion.
+Match the field literally with \V so no regex metacharacter can affect
+pattern parsing.
