Description

An out-of-bounds read issue was discovered in the HTTP/2 protocol decoder in HAProxy 1.8.x and 1.9.x through 1.9.0 which can result in a crash. The processing of the PRIORITY flag in a HEADERS frame requires 5 extra bytes, and while these bytes are skipped, the total frame length was not re-checked to make sure they were present in the frame.

Affected configurations

• haproxy haproxy (>= 1.8.0 <= 1.8.19) • haproxy haproxy 1.9.0 • opensuse leap 15.0 • canonical ubuntu linux 16.04 • canonical ubuntu linux 18.04 • canonical ubuntu linux 18.10 • redhat openshift container platform 3.11 • redhat enterprise linux 7.0 • redhat enterprise linux 7.4 • redhat enterprise linux 7.5 • redhat enterprise linux 7.6
