Is Symantec DLP vulnerable to CVE-2026-8458

Products

• Data Loss Prevention Core Package

Issue/Introduction

libcurl might in some circumstances reuse the wrong connection when asked to do Negotiate-authenticated ones, even when they are set to use different 'services'. libcurl features a pool of recent connections so that subsequent requests can reuse an existing connection to avoid overhead. When reusing a connection a range of criteria must be met. Due to a logical error in the code, a request that was issued by an application could wrongfully reuse an existing connection to the same server that was authenticated using different services.

Resolution

DLP does not use Negotiate (Kerberos/SPNEGO) authentication. CURLAUTH_NEGOTIATE, CURLOPT_SERVICE_NAME, and CURLOPT_PROXY_SERVICE_NAME are never set anywhere in the codebase.
