Description

This security bulletin contains information about 1 vulnerability.


1) Buffer Over-read (CVE-ID: CVE-2019-19240)

CWE-ID: CWE-126 - Buffer over-read

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N/E:U/U:Green


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.
