Synopsis

The Rocky Linux host is missing one or more security updates.

Description

The Rocky Linux 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the CIQ crlsa-2021_1608 advisory.

* python-cryptography: bleichenbacher timing oracle attack against RSA decryption (CVE-2020-25659)

* python-cryptography: certain sequences of update() calls when symmetrically encrypting very large payloads could result in an integer overflow and lead to buffer overflows (CVE-2020-36242)

Tenable has extracted the preceding description block directly from the CIQ security advisory.

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