PacketShaper 11.5.3 is a major maintenance release that resolves field support cases and contains a number of security and performance enhancements. This release replaces cryptographic algorithms DES and MD5 that are used in some functions with AES-256 and SHA-256 respectively, which provide enhanced security for both static and runtime data. In addition, v11.5.3 addresses a number of Common Vulnerabilities and Exposures (CVEs).
Customers running earlier PacketShaper 11.x versions are urged to upgrade to this latest release as soon as possible. Please consult the release notes for additional detail.
