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
The WAP interface in Trihedral VTScada (formerly VTS) 8.x through 11.x before 11.2.02 allows remote attackers to cause a denial of service (out-of-bounds read and application crash) via unspecified vectors.
