KB5042132: .NET 8.0 Security Update (August 2024)
KB5042132 is a High security update for .NET 8.0, released 2024-08-13. It closes 2 CVEs with a maximum CVSS of 7.5. It is the 21st largest of the 49 updates Microsoft shipped that month, by CVEs closed.
Update summary
Fixes 2 CVEs. Most severe CVSS 7.5 (High). EPSS exploit probability up to 2.7%. Among the top half of tracked Microsoft updates by EPSS exploit probability.
A newer security update for Microsoft Visual Studio 2022 version 17.10 has shipped since this one: KB5045993 (2024-10-08). For cumulative update families the newer package includes these fixes, so installing that one is usually the shorter path. Verify against your own update rings before you skip this package.
KB5042132 patches two vulnerabilities (CVE-2024-38167 and CVE-2024-38168) in Visual Studio 2022 versions 17.10 and 17.8 and the underlying .NET 8.0 runtime. The exposed population is developer workstations and build servers running these specific toolchains, not general end users. The High severity rating (CVSS 7.5) is offset by a low EPSS of 3 percent, with no CISA KEV listing or ransomware links, so this is a plan-and-schedule item rather than an emergency.
Do this: Push KB5042132 to developer machines and build agents running Visual Studio 2022 17.10, 17.8, or .NET 8.0 through your normal patch cycle this week.
