TLS session reuse can lead to host certificate verification bypass in node version < 12.18.0 and < 14.4.0.

An update of the nodejs package has been released.

The remote Rocky Linux 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the RLSA-2020:2852 advisory.

  - In nghttp2 before version 1.41.0, the overly large HTTP/2 SETTINGS frame payload causes denial of service.
    The proof of concept attack involves a malicious client constructing a SETTINGS frame with a length of     14,400 bytes (2400 individual settings entries) over and over again. The attack causes the CPU to spike at     100%. nghttp2 v1.41.0 fixes this vulnerability. There is a workaround to this vulnerability. Implement     nghttp2_on_frame_recv_callback callback, and if received frame is SETTINGS frame and the number of     settings entries are large (e.g., > 32), then drop the connection. (CVE-2020-11080)

  - minimist before 1.2.2 could be tricked into adding or modifying properties of Object.prototype using a     constructor or __proto__ payload. (CVE-2020-7598)

  - TLS session reuse can lead to host certificate verification bypass in node version < 12.18.0 and < 14.4.0.
    (CVE-2020-8172)

  - napi_get_value_string_*() allows various kinds of memory corruption in node < 10.21.0, 12.18.0, and <     14.4.0. (CVE-2020-8174)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Node.js reports :

Updates are now available for all supported Node.js release lines for the following issues. TLS session reuse can lead to host certificate verification bypass (High) (CVE-2020-8172) The 'session' event could be emitted before the 'secureConnect' event. It should not be, because the connection may fail to be authorized. If it was saved an authorized connection could be established later with the session ticket. Note that the https agent caches sessions, so is vulnerable to this.

The 'session' event will now only be emitted after the 'secureConnect' event, and only for authorized connections. HTTP/2 Large Settings Frame DoS (Low) (CVE-2020-11080) Receiving unreasonably large HTTP/2 SETTINGS frames can consume 100% CPU to process all the settings, blocking all other activities until complete.

The HTTP/2 session frame is limited to 32 settings by default. This can be configured if necessary using the maxSettings option.
napi_get_value_string_*() allows various kinds of memory corruption (High) (CVE-2020-8174) Calling napi_get_value_string_latin1(), napi_get_value_string_utf8(), or napi_get_value_string_utf16() with a non-NULL buf, and a bufsize of 0 will cause the entire string value to be written to buf, probably overrunning the length of the buffer.

A exploit has not been reported and it may be difficult but the following is suggested :

- All users of LTS Node.js versions should update to the versions announced in this security post. This will address the issue for any non pre-built add-on.

- Maintainers who support EOL Node.js versions and/or build against a version of Node.js that did not support N-API internally should update to use the new versions of node-addon-api 1.x and 2.x that will be released soon after this announcement. ICU-20958 Prevent SEGV_MAPERR in append (High) (CVE-2020-10531) An issue was discovered in International Components for Unicode (ICU) for C/C++ through 66.1. An integer overflow, leading to a heap-based buffer overflow, exists in the UnicodeString::doAppend() function in common/unistr.cpp.

Fix was applied to 10.x in an abundance of caution, even though there is no known way to trigger the overflow in 10.x.
