CVSS: 7.4EPSS: 0%CPEs: 3EXPL: 0CVE-2023-40548 – Shim: interger overflow leads to heap buffer overflow in verify_sbat_section on 32-bits systems
https://notcve.org/view.php?id=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. Se encontró un desbordamiento de búfer en Shim en el sistema de 32 bits. • https://access.redhat.com/errata/RHSA-2024:1834 https://access.redhat.com/errata/RHSA-2024:1835 https://access.redhat.com/errata/RHSA-2024:1873 https://access.redhat.com/errata/RHSA-2024:1876 https://access.redhat.com/errata/RHSA-2024:1883 https://access.redhat.com/errata/RHSA-2024:1902 https://access.redhat.com/errata/RHSA-2024:1903 https://access.redhat.com/errata/RHSA-2024:1959 https://access.redhat.com/errata/RHSA-2024:2086 https://access.redhat.com/security/cve&# • CWE-190: Integer Overflow or Wraparound CWE-787: Out-of-bounds Write •
