According to the versions of the ncurses packages installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :
There is a heap-based buffer over-read in the
_nc_find_entry function in tinfo/comp_hash.c in the terminfo library in ncurses before 6.1-20191012.(CVE-2019-17594)
There is a heap-based buffer over-read in the fmt_entry function in tinfo/comp_hash.c in the terminfo library in ncurses before 6.1-20191012.(CVE-2019-17595)
Note that Tenable Network Security has extracted the preceding description block directly from the EulerOS security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
