Base vector

AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H

Name of the Vulnerable Software and Affected Versions ncurses version 6.0

Description The issue is related to a NULL Pointer Dereference in the nc parse entry function of tinfo/parse entry.c. This could potentially lead to a remote denial of service attack if the terminfo library code is used to process untrusted terminfo data.

Recommendations For ncurses version 6.0, consider updating to a newer version that addresses this issue, as using untrusted terminfo data could lead to a denial of service attack. As a temporary workaround, restrict the use of the terminfo library to trusted data only.
