Security Bulletin
This security bulletin contains information about 7 vulnerabilities.
EUVDB-ID: #VU64067
Risk: Low
CVSSv3.1: 5.8 [CVSS:3.1/AV:L/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H/E:U/RL:O/RC:C]
CVE-ID: CVE-2022-28737
CWE-ID:
CWE-787 - Out-of-bounds write
Exploit availability: No
Description The vulnerability allows a local user to bypass implemented security restrictions.
The vulnerability exists due to a boundary error in the handle_image() function when shim tries to load and execute crafted EFI executables. A local privileged user can trigger an out-of-bounds write error and bypass secure boot protection mechanism.
MitigationUpdate the affected package shim to the latest version.

EUVDB-ID: #VU86241
Risk: Medium
CVSSv3.1: 4.6 [CVSS:3.1/AV:N/AC:H/PR:N/UI:R/S:U/C:N/I:N/A:H/E:U/RL:O/RC:C]
CVE-ID: CVE-2023-40546
CWE-ID:
CWE-476 - NULL Pointer Dereference
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to a NULL pointer dereference error within the mirror_one_esl() function in mok.c while creating a new ESL variable. A remote attacker can pass specially crafted data to the application and perform a denial of service (DoS) attack.
MitigationUpdate the affected package shim to the latest version.

EUVDB-ID: #VU86236
Risk: High
CVSSv3.1: 7.1 [CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H/E:U/RL:O/RC:C]
CVE-ID: CVE-2023-40547
CWE-ID:
CWE-345 - Insufficient Verification of Data Authenticity
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to compromise the affected system.
The vulnerability exists due to missing verification of data authenticity when parsing HTTP responses. A remote attacker can perform a man-in-the-middle (MitM) attack and use a specific malicious HTTP request, leading to a completely controlled out-of-bounds write primitive and complete system compromise.
This flaw is only exploitable during the early boot phase, an attacker needs to perform a Man-in-the-Middle or compromise the boot server to be able to exploit this vulnerability successfully.
MitigationUpdate the affected package shim to the latest version.

Risk: Medium
CVSSv3.1: 6.5 [CVSS:3.1/AV:N/AC:H/PR:N/UI:R/S:U/C:H/I:H/A:H/E:U/RL:O/RC:C]
CVE-ID: CVE-2023-40548
CWE-ID:
CWE-190 - Integer overflow
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to integer overflow within the verify_sbat_section on 32-bits systems. A remote attacker can pass a specially crafted PE binary to the application, trigger an integer overflow and execute arbitrary code on the target system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
MitigationUpdate the affected package shim to the latest version.

CVE-ID: CVE-2023-40549
CWE-ID:
CWE-125 - Out-of-bounds read
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to a boundary condition within the verify_buffer_authenticode() function when parsing PE binary. A remote attacker can pass a specially crafted PE binary to the loader, trigger an out-of-bounds read error and perform a denial of service (DoS) attack.
