Summary

Red Hat Security Advisory: edk2 security update

Notes

Topic

An update for edk2 is now available for Red Hat Enterprise Linux 8.6 Extended Update Support. Red Hat Product Security has rated this update as having a security impact of Moderate. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section.

Details

EDK (Embedded Development Kit) is a project to enable UEFI support for Virtual Machines. This package contains a sample 64-bit UEFI firmware for QEMU and KVM. Security Fix(es): * edk2: Function GetEfiGlobalVariable2() return value not checked in DxeImageVerificationHandler() (CVE-2019-14560) * openssl: Excessive time spent checking DH keys and parameters (CVE-2023-3446) For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section.

Firstly, while the potential for a Denial of Service (DoS) attack exists, it requires specific conditions to be met, notably the use of DH_check(), DH_check_ex(), or EVP_PKEY_param_check() functions with DH keys or parameters obtained from untrusted sources. Secondly, the issue primarily affects the efficiency of key and parameter checks, rather than directly compromising the security or integrity of cryptographic operations. Given these considerations and the absence of widespread exploitation or significant consequences beyond performance degradation, the overall impact of this vulnerability is deemed low rather than moderate.",
