Blue Coat products using Mozilla Network Security Services (NSS) for certificate validation are vulnerable to certificate validation flaw when validating RSA X.509 certificates. A remote attacker may exploit this vulnerability using a specially crafted X.509 certificate to spoof a legitimate certificate.
The following products are vulnerable:
Content Analysis System
CAS 1.1.x prior to 188.8.131.52 and 1.2.x prior to 184.108.40.206 are vulnerable. CAS 1.3 is not vulnerable.
Director 6.1 prior to 220.127.116.11 is vulnerable. Director uses NSS for update image downloads and connections to Blue Coat.
MC 1.x prior to 18.104.22.168 is vulnerable. MC 1.3, 1.4, 1.5, 1.6, 1.7, and 1.8 are not vulnerable. MC uses NSS for Java, SSH, and LDAPS connections.
SA 6.6 prior to 6.6.10, 7.0, and 7.1 prior to 7.1.5 are vulnerable. SA 7.2 is not vulnerable.
All versions of XOS are vulnerable. XOS uses NSS only for LDAPS connections, however LDAP is not enabled by default.

CVE-2014-1568 - 7.5 (HIGH) (AV:N/AC:L/Au:N/C:P/I:P/A:P)
The Mozilla Network Security Services (NSS) library incorrectly parses PKCS#1 v1.5 padded signatures. This flaw allows an attacker to forge a digital certificate when an RSA key with a low public exponent is used. This vulnerability is a variant of the Bleichenbacher flaw.
Blue Coat products that use the NSS library for signature validation of a client or server certificate are vulnerable. Certificates are validated most often during the SSL/TLS session establishment. Certificates may also be validated as part of certificate based authentication using other protocols.
