CVE-2026-32952: CWE-190: Integer Overflow or Wraparound in Azure go-ntlmssp
CVE-2026-32952 is a medium severity vulnerability in the Azure go-ntlmssp Go package used for NTLM/Negotiate HTTP authentication. Versions prior to 0. 1. 1 contain an integer overflow or wraparound issue (CWE-190) that can cause a slice out of bounds panic when processing a malicious NTLM challenge message. This panic can crash any Go process using ntlmssp. Negotiator as an HTTP transport, resulting in a denial of service. The issue is patched in version 0. 1. 1. No known exploits are reported in the wild.
AI Analysis
Technical Summary
The Azure go-ntlmssp package prior to version 0.1.1 suffers from an integer overflow or wraparound vulnerability (CWE-190) triggered by a malicious NTLM challenge message. This causes a slice out of bounds panic that crashes Go processes using ntlmssp.Negotiator as an HTTP transport. The vulnerability has a CVSS 3.1 base score of 5.3 (medium severity) with network attack vector, low attack complexity, no privileges or user interaction required, and impacts availability only. Version 0.1.1 includes a patch that fixes this issue. The package is used in cloud environments where the vendor manages patching.
Potential Impact
Successful exploitation results in a denial of service by crashing Go processes that use ntlmssp.Negotiator for HTTP transport. There is no impact on confidentiality or integrity. No known exploits are reported in the wild.
Mitigation Recommendations
A patch is available in version 0.1.1 of the go-ntlmssp package that addresses this vulnerability. Since this is a cloud service component, the vendor manages remediation for the hosted service. Users should upgrade to version 0.1.1 or later to mitigate the risk. Patch status is confirmed by the vendor advisory indicating the fix in version 0.1.1.
