If format strings can be influenced by an attacker, they can be exploited,
and note that sprintf variations do not always \0-terminate (CWE-134). Use
a constant for the format specification.

Statically-sized arrays can be improperly restricted, leading to potential
overflows or other issues (CWE-119!/CWE-120). Perform bounds checking, use
functions that limit length, or ensure that the size is larger than the
maximum possible length.

data/libparse-exuberantctags-perl-1.02/readtags.c:450:16: [2] (misc) fopen:

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