CVSS 3.0
7.5 highCVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:HCVE-2018-20615
High (7.5). EPSS 4.5% chance of exploitation in the next 30 days.
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.
