Am I affected?
Debian, Ubuntu or Red Hat sometimes backport a fix without changing the upstream version number: such a version reads « to verify », never « affected ».With a domain, we read the version its public headers and pages expose. A distribution build can carry the fix under an older number.
Description
A vulnerability has been identified in CP-8000 MASTER MODULE WITH I/O -25/+70°C (All versions < CPC80 V16.30), CP-8000 MASTER MODULE WITH I/O -40/+70°C (All versions < CPC80 V16.30), CP-8021 MASTER MODULE (All versions < CPC80 V16.30), CP-8022 MASTER MODULE WITH GPRS (All versions < CPC80 V16.30). When using the HTTPS server under specific conditions, affected devices do not properly free resources. This could allow an unauthenticated remote attacker to put the device into a denial of service condition.
