Summary
Red Hat Security Advisory: edk2 security, bug fix, and enhancement update
Notes
Topic
An update for edk2 is now available for Red Hat Enterprise Linux 9.
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: Possible DoS translating ASN.1 object identifiers (CVE-2023-2650)
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.
