Internet2 Shibboleth Service Provider software 1.3.x before 1.3.3 and 2.x before 2.2.1, when using PKIX trust validation, does not properly handle a '\0' character in the subject or subjectAltName fields of a certificate, which allows remote man-in-the-middle attackers to spoof arbitrary SSL servers via a crafted certificate issued by a legitimate Certification Authority, a related issue to CVE-2009-2408.

Security readout for executives and security teams

This flaw affects Shibboleth Service Provider systems using PKIX certificate trust validation. A specially crafted certificate from a legitimate CA could let an attacker in a man-in-the-middle position impersonate SSL servers, undermining trusted SSO or federation connections. Exposure is most likely where legacy Shibboleth Service Provider deployments use PKIX trust validation and remain below 1.3.3 or 2.2.1. The bundle does not identify other products. Treat as high priority for any active Shibboleth SP environment, especially identity federation. The issue can weaken trust in encrypted server identity, but risk depends on legacy version presence and PKIX use. Mitigation focus: Upgrade Shibboleth SP 1.3.x to 1.3.3 or later.; Upgrade Shibboleth SP 2.x to 2.2.1 or later.; Review Shibboleth and Debian advisories for package-specific guidance..
