"Description": "This update upgrades shim to version 15.8-alt1. \nSecurity Fix(es):\n\n * BDU:2023-06578: Уязвимость компонента fs/ntfs.c загрузчика операционных систем Grub2, позволяющая нарушителю получить несанкционированный доступ к защищаемой информации\n\n * BDU:2023-06822: Уязвимость компонента fs/ntfs.c загрузчика операционных систем Grub2, позволяющая нарушителю выполнить произвольный код\n\n * BDU:2024-00725: Уязвимость UEFI-загрузчика shim, существующая из-за непринятия мер по нейтрализации специальных элементов, позволяющая нарушителю выполнить произвольный код\n\n * CVE-2023-40546: A flaw was found in Shim when an error happened while creating a new ESL variable. If Shim fails to create the new variable, it tries to print an error message to the user; however, the number of parameters used by the logging function doesn't match the format string used by it, leading to a crash under certain circumstances.\n\n * CVE-2023-40547: A remote code execution vulnerability was found in Shim. The Shim boot support trusts attacker-controlled values when parsing an HTTP response. This flaw allows an attacker to craft 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.\n\n * CVE-2023-40548: A buffer overflow was found in Shim in the 32-bit system. The overflow happens due to an addition operation involving a user-controlled value parsed from the PE binary being used by Shim. This value is further used for memory allocation operations, leading to a heap-based buffer overflow. This flaw causes memory corruption and can lead to a crash or data integrity issues during the boot phase.\n\n * CVE-2023-40549: An out-of-bounds read flaw was found in Shim due to the lack of proper boundary verification during the load of a PE binary. This flaw allows an attacker to load a crafted PE binary, triggering the issue and crashing Shim, resulting in a denial of service.\n\n * CVE-2023-40550: An out-of-bounds read flaw was found in Shim when it tried to validate the SBAT information. This issue may expose sensitive data during the system's boot phase.\n\n * CVE-2023-40551: A flaw was found in the MZ binary format in Shim. An out-of-bounds read may occur, leading to a crash or possible exposure of sensitive data during the system's boot phase.\n\n * CVE-2023-4692: An out-of-bounds write flaw was found in grub2's NTFS filesystem driver. This issue may allow an attacker to present a specially crafted NTFS filesystem image, leading to grub's heap metadata corruption. In some circumstances, the attack may also corrupt the UEFI firmware heap metadata. As a result, arbitrary code execution and secure boot protection bypass may be achieved.\n\n * CVE-2023-4693: An out-of-bounds read flaw was found on grub2's NTFS filesystem driver. This issue may allow a physically present attacker to present a specially crafted NTFS file system image to read arbitrary memory locations. A successful attack allows sensitive data cached in memory or EFI variable values to be leaked, presenting a high Confidentiality risk.",
