Fedora 39 : firecracker / rust-aes-gcm (2023-17bdd59177)

medium Nessus Plugin ID 185319

Language:

Synopsis

The remote Fedora host is missing one or more security updates.

Description

The remote Fedora 39 host has packages installed that are affected by a vulnerability as referenced in the FEDORA-2023-17bdd59177 advisory.

 - aes-gcm is a pure Rust implementation of the AES-GCM. Starting in version 0.10.0 and prior to version 0.10.3, in the AES GCM implementation of decrypt_in_place_detached, the decrypted ciphertext (i.e. the correct plaintext) is exposed even if tag verification fails. If a program using the `aes-gcm` crate's `decrypt_in_place*` APIs accesses the buffer after decryption failure, it will contain a decryption of an unauthenticated input. Depending on the specific nature of the program this may enable Chosen Ciphertext Attacks (CCAs) which can cause a catastrophic breakage of the cipher including full plaintext recovery.
 Version 0.10.3 contains a fix for this issue. (CVE-2023-42811)

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

Solution

Update the affected firecracker and / or rust-aes-gcm packages.
