Buffer Overflow vulnerability in postprocess_terminfo function in tinfo/parse_entry.c:997 in ncurses 6.1 allows remote attackers to cause a denial of service via crafted command.

The remote Redhat Enterprise Linux 8 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: Heap buffer overflow in _nc_find_entry in tinfo/comp_hash.c:70 (CVE-2020-19190)

  - ncurses: heap-based buffer overflow in _nc_captoinfo() in captoinfo.c (CVE-2021-39537)

  - 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)

Note that Nessus has not tested for these issues but has instead relied on the package manager's report that the package is installed.

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

    (CVE-2023-3618)

  - When curl retrieves an HTTP response, it stores the incoming headers so that they can be accessed later     via the libcurl headers API. However, curl did not have a limit in how many or how large headers it would     accept in a response, allowing a malicious server to stream an endless series of headers and eventually     cause curl to run out of heap memory. (CVE-2023-38039)

  - This flaw makes curl overflow a heap based buffer in the SOCKS5 proxy handshake. When curl is asked to     pass along the host name to the SOCKS5 proxy to allow that to resolve the address instead of it getting     done by curl itself, the maximum length that host name can be is 255 bytes. If the host name is detected     to be longer, curl switches to local name resolving and instead passes on the resolved address only. Due     to this bug, the local variable that means let the host resolve the name could get the wrong value     during a slow SOCKS5 handshake, and contrary to the intention, copy the too long host name to the target     buffer instead of copying just the resolved address there. The target buffer being a heap based buffer,     and the host name coming from the URL that curl has been told to operate with. (CVE-2023-38545)

  - CVE-2023-38545 is a heap-based buffer overflow vulnerability in the SOCKS5 proxy handshake in libcurl and     curl.  When curl is given a hostname to pass along to a SOCKS5 proxy that is greater than 255 bytes in     length, it will switch to local name resolution in order to resolve the address before passing it on to     the SOCKS5 proxy. However, due to a bug introduced in 2020, this local name resolution could fail due to a     slow SOCKS5 handshake, causing curl to pass on the hostname greater than 255 bytes in length into the     target buffer, leading to a heap overflow.  The advisory for CVE-2023-38545 gives an example exploitation     scenario of a malicious HTTPS server redirecting to a specially crafted URL. While it might seem that an     attacker would need to influence the slowness of the SOCKS5 handshake, the advisory states that server     latency is likely slow enough to trigger this bug. (CVE-2023-38545)

  - This flaw allows an attacker to insert cookies at will into a running program using libcurl, if the     specific series of conditions are met. libcurl performs transfers. In its API, an application creates     easy handles that are the individual handles for single transfers. libcurl provides a function call that     duplicates en easy handle called     [curl_easy_duphandle](https://curl.se/libcurl/c/curl_easy_duphandle.html). If a transfer has cookies     enabled when the handle is duplicated, the cookie-enable state is also cloned - but without cloning the     actual cookies. If the source handle did not read any cookies from a specific file on disk, the cloned     version of the handle would instead store the file name as `none` (using the four ASCII letters, no     quotes). Subsequent use of the cloned handle that does not explicitly set a source to load cookies from     would then inadvertently load cookies from a file named `none` - if such a file exists and is readable in     the current directory of the program using libcurl. And if using the correct file format of course.
    (CVE-2023-38546)

  - CVE-2023-38546 is a cookie injection vulnerability in the curl_easy_duphandle(), a function in libcurl     that duplicates easy handles.  When duplicating an easy handle, if cookies are enabled, the duplicated     easy handle will not duplicate the cookies themselves, but would instead set the filename to none.'     Therefore, when the duplicated easy handle is subsequently used, if a source was not set for the cookies,     libcurl would attempt to load them from the file named none' on the disk.  This vulnerability is rated     low, as the various conditions required for exploitation are unlikely.  (CVE-2023-38546)
