EulerOS 2.0 SP3 : ncurses (EulerOS-SA-2019-2634)

medium Nessus Plugin ID 132169

Synopsis

The remote EulerOS host is missing multiple security updates.

Description

According to the versions of the ncurses packages installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :

 - 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)

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.

Solution
