SCA: security update for openpgp (GHSA-8qff-qr5q-5pr8)

high Tenable Cloud Security Plugin ID 427728

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

- OpenPGP.js is a JavaScript implementation of the OpenPGP protocol. Startinf in version 5.0.1 and prior to
versions 5.11.3 and 6.1.1, a maliciously modified message can be passed to either `openpgp.verify` or
`openpgp.decrypt`, causing these functions to return a valid signature verification result while returning
data that was not actually signed. This flaw allows signature verifications of inline (non-detached)
signed messages (using `openpgp.verify`) and signed-and-encrypted messages (using `openpgp.decrypt` with
`verificationKeys`) to be spoofed, since both functions return extracted data that may not match the data
that was originally signed. Detached signature verifications are not affected, as no signed data is
returned in that case. In order to spoof a message, the attacker needs a single valid message signature
(inline or detached) as well as the plaintext data that was legitimately signed, and can then construct an
inline-signed message or signed-and-encrypted message with any data of the attacker's choice, which will
appear as legitimately signed by affected versions of OpenPGP.js. In other words, any inline-signed
message can be modified to return any other data (while still indicating that the signature was valid),
and the same is true for signed+encrypted messages if the attacker can obtain a valid signature and
encrypt a new message (of the attacker's choice) together with that signature. The issue has been patched
in versions 5.11.3 and 6.1.1. Some workarounds are available. When verifying inline-signed messages,
extract the message and signature(s) from the message returned by `openpgp.readMessage`, and verify
the(/each) signature as a detached signature by passing the signature and a new message containing only
the data (created using `openpgp.createMessage`) to `openpgp.verify`. When decrypting and verifying
signed+encrypted messages, decrypt and verify the message in two steps, by first calling `openpgp.decrypt`
without `verificationKeys`, and then passing the returned signature(s) and a new message containing the
decrypted data (created using `openpgp.createMessage`) to `openpgp.verify`. (CVE-2025-47934)
