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
In Wind River VxWorks 6.9 and 7, a specific crafted packet may lead to an out-of-bounds read during an IKE initial exchange scenario.
