data/ibus-libzhuyin-1.9.1/src/ZYString.h:38:14: [4] (format) printf:
If format strings can be influenced by an attacker, they can be exploited
(CWE-134). Use a constant for the format specification.

Environment variables are untrustable input if they can be set by an
attacker. They can have any content and length, and the same variable can
be set more than once (CWE-807, CWE-20). Check environment variables
carefully before using them.

around to create a race condition, control its ancestors, or change its
contents? (CWE-362).
