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 nc find entry function, located in the tinfo/comp hash.c file of the terminfo library in ncurses. This could potentially allow an attacker to impact the confidentiality, integrity, and availability of protected information.

Recommendations For versions prior to 6.1-20191012, update to version 6.1-20191012 or later to resolve the issue. As a temporary workaround, consider restricting access to the vulnerable nc find entry function until a patch is available.
