The remote AlmaLinux 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the ALSA-2022:6964 advisory.
Node.js made calls to EntropySource() in SecretKeyGenTraits::DoKeyGen() in src/crypto/crypto_keygen.cc.
However, it does not check the return value, it assumes EntropySource() always succeeds, but it can (and sometimes will) fail. Thank you, Ben Noordhuis for reporting (and fixing!) this vulnerability. Impacts:
(CVE-2022-35255)
The llhttp parser in the http module in Node.js v18.7.0 does not correctly handle header fields that are not terminated with CLRF. This may result in HTTP Request Smuggling. Thank you, VVX7 for reporting this vulnerability. Impacts: (CVE-2022-35256)
Note that Nessus has not tested for these issues but has instead relied only on the application’s self-reported version number.
