Description

This update fixes a bug in the SSH parser, where a malformed banner could lead to evasion of SSH rules and missing log entries. In some cases it may also lead to a crash, CVE-2014-6603. Additionally, this release also addresses a new IPv6 issue that can lead to evasion.

Note that Tenable Network Security has extracted the preceding description block directly from the Fedora security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
