    (CVE-2023-50495)

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.

The remote Redhat Enterprise Linux 7 host has one or more packages installed that are affected by multiple vulnerabilities that have been acknowledged by the vendor but will not be patched.

  - ncurses: Stack-based buffer overflow caused by format string vulnerability in fmt_entry function     (CVE-2017-10685)

  - In ncurses 6.0, there is a stack-based buffer overflow in the fmt_entry function. A crafted input will     lead to a remote arbitrary code execution attack. (CVE-2017-10684)

  - In ncurses 6.0, there is an attempted 0xffffffffffffffff access in the append_acs function of     tinfo/parse_entry.c. It could lead to a remote denial of service attack if the terminfo library code is     used to process untrusted terminfo data. (CVE-2017-11112)

  - In ncurses 6.0, there is a NULL Pointer Dereference in the _nc_parse_entry function of     tinfo/parse_entry.c. It could lead to a remote denial of service attack if the terminfo library code is     used to process untrusted terminfo data. (CVE-2017-11113)

  - 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)

  - 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 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 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 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 _nc_safe_strcat function in strings.c in ncurses 6.0 that will     lead to a remote denial of service attack. (CVE-2017-13734)

  - Rejected reason: DO NOT USE THIS CANDIDATE NUMBER. ConsultIDs: none. Reason: This candidate was withdrawn     by its CNA. Further investigation showed that it was not a security issue. Notes: none (CVE-2018-10754)

  - 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)

  - In ncurses, possibly a 6.x version, there is a NULL pointer dereference at the function _nc_name_match     that will lead to a denial of service attack. NOTE: the original report stated version 6.1, but the issue     did not reproduce for that version according to the maintainer or a reliable third-party (CVE-2018-19217)

  - Buffer Overflow vulnerability in one_one_mapping function in progs/dump_entry.c:1373 in ncurses 6.1 allows     remote attackers to cause a denial of service via crafted command. (CVE-2020-19185)

  - Buffer Overflow vulnerability in _nc_find_entry in tinfo/comp_hash.c:70 in ncurses 6.1 allows remote     attackers to cause a denial of service via crafted command. (CVE-2020-19190)

  - An issue was discovered in ncurses through v6.2-1. _nc_captoinfo in captoinfo.c has a heap-based buffer     overflow. (CVE-2021-39537)

  - ncurses before 6.4 20230408, when used by a setuid application, allows local users to trigger security-     relevant memory corruption via malformed data in a terminfo database file that is found in $HOME/.terminfo     or reached via the TERMINFO or TERM environment variable. (CVE-2023-29491)

  - NCurse v6.4-20230418 was discovered to contain a segmentation fault via the component _nc_wrap_entry().
    (CVE-2023-50495)
