Synopsis

The remote Oracle Linux host is missing one or more security updates.

Description

The remote Oracle Linux 9 host has packages installed that are affected by multiple vulnerabilities as referenced in the ELSA-2023-2487 advisory.

 - A flaw was found in CryptoPro Secure Disk bootloaders before 2022-06-01. An attacker may use this bootloader to bypass or tamper with Secure Boot protections. In order to load and execute arbitrary code in the pre-boot stage, an attacker simply needs to replace the existing signed bootloader currently in use with this bootloader. Access to the EFI System Partition is required for booting using external media.
 (CVE-2022-34301)

 - A flaw was found in New Horizon Datasys bootloaders before 2022-06-01. An attacker may use this bootloader to bypass or tamper with Secure Boot protections.

Access to the EFI System Partition is required for booting using external media.
 (CVE-2022-34302)

 - When creating an OPERATOR user account on the BMC, the redfish plugin saved the auto-generated password to /etc/fwupd/redfish.conf without proper restriction, allowing any user on the system to read the same configuration file. (CVE-2022-3287)

 - A flaw was found in Eurosoft bootloaders before 2022-06-01. An attacker may use this bootloader to bypass or tamper with Secure Boot protections.
