KB5041592: Windows 11 version 21H2 Security Update (August 2024)

critical Nessus Plugin ID 205450

Language:

Synopsis

The remote Windows host is affected by multiple vulnerabilities.

Description

The remote Windows host is missing security update 5041592. 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 This can allow an attacker with administrator privileges to replace current versions of Windows system files with outdated versions.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.
