Description

This security bulletin contains information about 4 vulnerabilities.


1) Resource exhaustion (CVE-ID: CVE-2026-26171)

CWE-ID: CWE-400 - Resource exhaustion

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Green


The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to application does not properly control consumption of internal resources in .NET. A remote attacker can trigger resource exhaustion and perform a denial of service (DoS) attack.


2) Improper Neutralization of Special Elements (CVE-ID: CVE-2026-32178)

CWE-ID: CWE-138 - Improper Neutralization of Special Elements

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N/E:U/U:Green


The vulnerability allows a remote attacker to compromise the target system.

The vulnerability exists due to improper neutralization of special elements in .NET. A remote attacker can perform spoofing attack.


3) Stack-based buffer overflow (CVE-ID: CVE-2026-32203)

CWE-ID: CWE-121 - Stack-based buffer overflow

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Green


The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to a boundary error in .NET and Visual Studio. A remote unauthenticated attacker can trigger stack-based buffer overflow and cause a denial of service condition on the target system.


4) Infinite loop (CVE-ID: CVE-2026-33116)

CWE-ID: CWE-835 - Loop with Unreachable Exit Condition ('Infinite Loop')

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Green


The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to infinite loop in .NET, .NET Framework, and Visual Studio. A remote attacker can consume all available system resources and cause denial of service conditions.
