Debian DSA-1896-1 : opensaml, shibboleth-sp - several vulnerabilities

high Nessus Plugin ID 44761

Language:

Synopsis

The remote Debian host is missing a security-related update.

Description

Several vulnerabilities have been discovered in the opensaml and shibboleth-sp packages, as used by Shibboleth 1.x :

 - Chris Ries discovered that decoding a crafted URL leads to a crash (and potentially, arbitrary code execution).
 - Ian Young discovered that embedded NUL characters in certificate names were not correctly handled, exposing configurations using PKIX trust validation to impersonation attacks.

 - Incorrect processing of SAML metadata ignored key usage constraints.

Solution

Upgrade the Shibboleth 1.x packages.

For the old stable distribution (etch), these problems have been fixed in version 1.3f.dfsg1-2+etch1 of the shibboleth-sp packages, and version 1.1a-2+etch1 of the opensaml packages.


For the stable distribution (lenny), these problems have been fixed in version 1.3.1.dfsg1-3+lenny1 of the shibboleth-sp packages, and version 1.1.1-2+lenny1 of the opensaml packages.

This update requires restarting the affected services (mainly Apache) to become effective.
