Off-by-one error in the XML signature feature in Apache XML Security for C++ 1.6.0, as used in Shibboleth before 2.4.3 and possibly other products, allows remote attackers to cause a denial of service (crash) via a signature using a large RSA key, which triggers a buffer overflow.

The Shibboleth authentication module 5.x before 5.x-3.4 and 6.x before 6.x-3.2, a module for Drupal, does not properly remove statically granted privileges after a logout or other session change, which allows physically proximate attackers to gain privileges by using an unattended web browser.

Multiple cross-site scripting (XSS) vulnerabilities in the Identity Provider (IdP) 1.3.x before 1.3.4 and 2.x before 2.1.5, and the Service Provider 1.3.x before 1.3.5 and 2.x before 2.3, in Internet2 Middleware Initiative Shibboleth allow remote attackers to inject arbitrary web script or HTML via URLs that are encountered in redirections, and appear in automatically generated forms.

Buffer overflow in OpenSAML before 1.1.3 as used in Internet2 Shibboleth Service Provider software 1.3.x before 1.3.4, and XMLTooling before 1.2.2 as used in Internet2 Shibboleth Service Provider software 2.x before 2.2.1, allows remote attackers to cause a denial of service and possibly execute arbitrary code via a malformed encoded URL.

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.

OpenSAML 2.x before 2.2.1 and XMLTooling 1.x before 1.2.1, as used by Internet2 Shibboleth Service Provider 2.x before 2.2.1, do not follow the KeyDescriptor element's Use attribute, which allows remote attackers to use a certificate for both signing and encryption when it is designated for just one purpose, potentially weakening the intended security application of the certificate.
