Advisory Details: 

This Security Advisory addresses multiple vulnerabilities announced in OpenSSL
Security Advisory [26 Jan 2017]. Blue Coat products that include a vulnerable
version of OpenSSL and make use of the affected functionality are vulnerable.

CVE-2017-3730 is a NULL pointer dereference flaw in the SSL client
implementation. A remote attacker can send crafted DHE or ECDHE key
exchange parameters to an SSL client and cause an application crash,
resulting in denial of service.

CVE-2017-3731 is an out-of-bounds read flaw in the SSL client and server
implementations on 32-bit platforms. A remote attacker can send crafted
packets and cause an application crash, resulting in denial of service.

CVE-2017-3732 is a flaw in the 64-bit Montgomery squaring implementation
used in the RSA, DSA, and DHE algorithms. A remote attacker can exploit the
vulnerability to obtain private key information.

Blue Coat products that use a native installation of OpenSSL but do not install
or maintain that implementation are not vulnerable to any of these CVEs.
However, the underlying platform or application that installs and maintains
OpenSSL may be vulnerable. Blue Coat urges our customers to update the
versions of OpenSSL that are natively installed for Client Connector for OS X,
Proxy Client for OS X, and Reporter 9.x for Linux.

Some Blue Coat products do not enable or use all functionality within OpenSSL.
The products listed below do not utilize the functionality described in the
CVEs below and are thus not known to be vulnerable to them. However, fixes for
these CVEs will be included in the patches that are provided.

Android Mobile Agent: CVE-2017-3731
ASG: CVE-2017-3731
