SECURITY UPDATE: stack buffer overflow in the infocmp -i option
debian/patches/CVE-2025-69720.patch: in analyze_string() in
progs/infocmp.c, clamp the copy length taken from strlen(cp) to
MAX_TERMINFO_LENGTH and grow buf2 by one byte for the terminating
NUL, so an over-long capability string can no longer overflow the
fixed-size stack buffer.
