Synopsis

The remote Red Hat host is missing one or more security updates for ncurses.

Description

The remote Redhat Enterprise Linux 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2021:4426 advisory.

 The ncurses (new curses) library routines are a terminal-independent method of updating character screens with reasonable optimization. The ncurses packages contain support utilities including a terminfo compiler tic, a decompiler infocmp, clear, tput, tset, and a termcap conversion tool captoinfo.

 Security Fix(es):

 * ncurses: heap-based buffer overflow in the _nc_find_entry function in tinfo/comp_hash.c (CVE-2019-17594)

 * ncurses: heap-based buffer overflow in the fmt_entry function in tinfo/comp_hash.c (CVE-2019-17595)
