The remote Windows host is missing security update 5041571. It is, therefore, affected by multiple vulnerabilities

  - An elevation of privilege vulnerability exists in Windows based systems supporting Virtualization Based     Security (VBS) including a subset of Azure Virtual Machine SKUS. This can allow an attacker with     administrator privileges to replace current versions of Windows system files with outdated versions. By     exploiting this vulnerability, an attacker could reintroduce previously mitigated vulnerabilities,     circumvent some features of VBS, and exfiltrate data protected by VBS. (CVE-2024-21302)

  - A buffer overflow was found in grub_font_construct_glyph(). A malicious crafted pf2 font can lead to an     overflow when calculating the max_glyph_size value, allocating a smaller than needed buffer for the glyph,     this further leads to a buffer overflow and a heap based out-of-bounds write. An attacker may use this     vulnerability to circumvent the secure boot mechanism. (CVE-2022-2601)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

An attacker may use this     vulnerability to circumvent the secure boot mechanism. (CVE-2022-2601)

  - 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.
    (CVE-2023-40547)

  - When rendering certain unicode sequences, grub2's font code doesn't proper validate if the informed     glyph's width and height is constrained within bitmap size. As consequence an attacker can craft an input     which will lead to a out-of-bounds write into grub2's heap, leading to memory corruption and availability     issues. Although complex, arbitrary code execution could not be discarded. (CVE-2022-3775)
