Name of the Vulnerable Software and Affected Versions ncurses versions prior to 6.1-20191012

Description The issue is related to a heap-based buffer over-read in the fmt entry function in tinfo/comp hash.c of the terminfo library. This could allow a remote attacker to disclose protected information and cause a denial of service.
