Summary

Red Hat Security Advisory: shim bug fix update

Notes

Topic

An update for shim is now available for Red Hat Enterprise Linux 9. Red Hat Product Security has rated this update as having a security impact of Important. 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

The shim package contains a first-stage UEFI boot loader that handles chaining to a trusted full boot loader under secure boot environments. Security Fix(es): * shim: RCE in http boot support may lead to Secure Boot bypass (CVE-2023-40547) * shim: Interger overflow leads to heap buffer overflow in verify_sbat_section on 32-bits systems (CVE-2023-40548) * shim: Out-of-bounds read printing error messages (CVE-2023-40546) * shim: Out-of-bounds read in verify_buffer_authenticode() malformed PE file (CVE-2023-40549) * shim: Out-of-bound read in verify_buffer_sbat() (CVE-2023-40550) * shim: out of bounds read when parsing MZ binaries (CVE-2023-40551) 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.

Summary

Red Hat Security Advisory: shim security update

Notes

Topic

An update for shim is now available for Red Hat Enterprise Linux 9.0 Extended Update Support. Red Hat Product Security has rated this update as having a security impact of Important. 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

The shim package contains a first stage UEFI boot loader that handles chaining to a trusted full boot loader under secure boot environments. Security Fix(es): * shim: RCE in http boot support may lead to Secure Boot bypass (CVE-2023-40547) * shim: Interger overflow leads to heap buffer overflow in verify_sbat_section on 32-bits systems (CVE-2023-40548) * shim: Out-of-bounds read printing error messages (CVE-2023-40546) * shim: Out-of-bounds read in verify_buffer_authenticode() malformed PE file (CVE-2023-40549) * shim: Out-of-bound read in verify_buffer_sbat() (CVE-2023-40550) * shim: out of bounds read when parsing MZ binaries (CVE-2023-40551) 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.

Therefore GRUB2 MUST be updated to the latest\nversion: grub2-2.02-0.87.el7_9.14 BEFORE or SIMULTANEOUSLY with this shim in order for Secure Boot to continue to work.

Notes

Title of the patch

Security update for shim

Description of the patch

This update for shim fixes the following issues: - Update shim-install to set the TPM2 SRK algorithm (bsc#1213945) - Limit the requirement of fde-tpm-helper-macros to the distro with suse_version 1600 and above (bsc#1219460) Update to version 15.8: Security issues fixed: - mok: fix LogError() invocation (bsc#1215099,CVE-2023-40546) - avoid incorrectly trusting HTTP headers (bsc#1215098,CVE-2023-40547) - Fix integer overflow on SBAT section size on 32-bit system (bsc#1215100,CVE-2023-40548) - Authenticode: verify that the signature header is in bounds (bsc#1215101,CVE-2023-40549) - pe: Fix an out-of-bound read in verify_buffer_sbat() (bsc#1215102,CVE-2023-40550) - pe-relocate: Fix bounds check for MZ binaries (bsc#1215103,CVE-2023-40551) The NX flag is disable which is same as the default value of shim-15.8, hence, not need to enable it by this patch now. - Generate dbx during build so we don't include binary files in sources - Don't require grub so shim can still be used with systemd-boot - Update shim-install to fix boot failure of ext4 root file system on RAID10 (bsc#1205855) - Adopt the macros from fde-tpm-helper-macros to update the signature in the sealed key after a bootloader upgrade - Update shim-install to amend full disk encryption support - Adopt TPM 2.0 Key File for grub2 TPM 2.0 protector - Use the long name to specify the grub2 key protector - cryptodisk: support TPM authorized policies - Do not use tpm_record_pcrs unless the command is in command.lst - Removed POST_PROCESS_PE_FLAGS=-N from the build command in shim.spec to enable the NX compatibility flag when using post-process-pe after discussed with grub2 experts in mail. It's useful for further development and testing. (bsc#1205588)

It\u0027s useful for further development\n  and testing. (bsc#1205588)\n",

It\u0027s useful for further development\n  and testing. (bsc#1205588)\n",
