Oracle Linux 9 : skopeo (ELSA-2024-2239)

high Nessus Plugin ID 195076

Synopsis

The remote Oracle Linux host is missing a security update.

Description

The remote Oracle Linux 9 host has packages installed that are affected by a vulnerability as referenced in the ELSA-2024-2239 advisory.

- Before Go 1.20, the RSA based TLS key exchanges used the math/big library, which is not constant time. RSA blinding was applied to prevent timing attacks, but analysis shows this may not have been fully effective.
In particular it appears as if the removal of PKCS#1 padding may leak timing information, which in turn could be used to recover session key bits. In Go 1.20, the crypto/tls library switched to a fully constant time RSA implementation, which we do not believe exhibits any timing side channels. (CVE-2023-45287)

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 skopeo and / or skopeo-tests packages.
