Rocky Linux 8 : nodejs:10 (RLSA-2020:2848)
high Nessus Plugin ID 184927
Synopsis
The remote Rocky Linux host is missing one or more security updates.Description
The remote Rocky Linux 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the RLSA-2020:2848 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)
- 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.
Solution
Update the affected nodejs-nodemon and / or nodejs-packaging packages.See Also
