Description
The vulnerability allows a remote attacker to gain access to potentially sensitive information.
The vulnerability exists in the "websRedirect" function due to a boundary condition in processing redirected HTTP requests when supplied with a very large Host header. This can cause a copy of the Host header to fail, leaving that buffer uninitialized. A remote attacker can trigger out-of-bounds read error and read contents of memory on the system.
Remediation
Install updates from vendor's website.
