CVE-2020-14310 is fixed in 54 products on 1 platform, first by RHSA-2020:3216, released July 29, 2020. It is not reported as exploited. Patch Radar priority: Routine. - Web page: https://patchblox.com/security/cve/CVE-2020-14310 - Priority: Routine - CVSS: 6.0 (Moderate) - EPSS: 0.0046 - CISA KEV: not listed - Exploited (vendor report): no - Publicly disclosed: no - Published: Jul 29, 2020 ## Description 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 fwupd 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 score, acknowledgments, and other related information, refer to the CVE
