Published: 2020-01-23 13:10:23
CVE Author: NIST National Vulnerability Database

CVSS Base Vector:
AV:N/AC:M/Au:N/C:P/I:N/A:P

Summary:
The remote host is missing an update for the Huawei EulerOS 'ncurses' Linux Distribution Package(s) announced via the EulerOS-SA-2019-2634 advisory.

Detection Method:
Checks if a vulnerable Linux Distribution Package version is present on the target host.

Technical Details:
In ncurses 6.1, there is a NULL pointer dereference at function _nc_parse_entry in parse_entry.c that will lead to a denial of service attack. The product proceeds to the dereference code path even after a 'dubious character `*' in name or alias field' detection.(CVE-2018-19211) 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) There is an illegal address access in the _nc_safe_strcat function in strings.c in ncurses 6.0 that will lead to a remote denial of service attack.(CVE-2017-13734) There is an illegal address access in the _nc_save_str function in alloc_entry.c in ncurses 6.0. It will lead to a remote denial of service attack.(CVE-2017-13729) There is an illegal address access in the fmt_entry function in progs/dump_entry.c in ncurses 6.0 that might lead to a remote denial of service attack.(CVE-2017-13733) There is an illegal address access in the function _nc_read_entry_source() in progs/tic.c in ncurses 6.0 that might lead to a remote denial of service attack.(CVE-2017-13730) There is an illegal address access in the function dump_uses() in progs/dump_entry.c in ncurses 6.0 that might lead to a remote denial of service attack.(CVE-2017-13732) There is an illegal address access in the function postprocess_termcap() in parse_entry.c in ncurses 6.0 that will lead to a remote denial of service attack.(CVE-2017-13731) There is an infinite loop in the next_char function in comp_scan.c in ncurses 6.0, related to libtic. A crafted input will lead to a remote denial of service attack.(CVE-2017-13728)

Affected Versions:
'ncurses' Linux Distribution Package(s) on Huawei EulerOS V2.0SP3.

Recommendations:
Please install the updated Linux Distribution Package(s).

Solution Type:
Vendor Patch

Detection Type:
Linux Distribution Package

Vulnerability management is the process in which vulnerabilities in IT are identified and the risks of these vulnerabilities are evaluated. This evaluation leads to correcting the vulnerabilities and removing the risk or a formal risk acceptance by the management of an organization. The term vulnerability management is often confused with vulnerability scanning. Despite the fact both are related, there is an important difference between the two. Vulnerability scanning consists of using a computer program to identify vulnerabilities in networks, computer infrastructure or applications. Vulnerability management is the process surrounding vulnerability scanning, also taking into account other aspects such as risk acceptance, remediation etc. Source: "Implementing a Vulnerability Management Process".
