Vulnerability Insight:
The grub2 packages provide version 2 of the Grand Unified Boot Loader
(GRUB), a highly configurable and customizable boot loader with modular
architecture. The packages support a variety of kernel formats, file
systems, computer architectures, and hardware devices.

The shim package contains a first-stage UEFI boot loader that handles
chaining to a trusted full boot loader under secure boot environments.

The fwupdate packages provide a service that allows session software to
update device firmware.

Security Fix(es):

* grub2: Crafted grub.cfg file can lead to arbitrary code execution during
boot process (CVE-2020-10713)

* grub2: grub_malloc does not validate allocation size allowing for
arithmetic overflow and subsequent heap-based buffer overflow
(CVE-2020-14308)

* grub2: Integer overflow in grub_squash_read_symlink may lead to
heap-based buffer overflow (CVE-2020-14309)

* grub2: Integer overflow read_section_as_string may lead to heap-based
buffer overflow (CVE-2020-14310)

* grub2: Integer overflow in grub_ext2_read_link leads to heap-based buffer
overflow (CVE-2020-14311)

* grub2: Fail kernel validation without shim protocol (CVE-2020-15705)

* grub2: Use-after-free redefining a function whilst the same function is
already executing (CVE-2020-15706)

* grub2: Integer overflow in initrd size handling (CVE-2020-15707)

For more details about the security issue(s), including the impact, a CVSS

Users of grub2 are advised to upgrade to these updated packages, which fix
these bugs.
