Name of the Vulnerable Software and Affected Versions: FortiWeb versions 6.3.0 through 6.3.7 FortiWeb versions prior to 6.2.4

Description: A stack-based buffer overflow issue may allow a remote, unauthenticated attacker to crash the httpd daemon thread by sending a request with a crafted cookie header.

Recommendations: For FortiWeb versions 6.3.0 through 6.3.7, update to a version outside of this range to resolve the issue.
